When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.\n\n**Prerequisites.** - The attacker must have the ability to modify non-executable files consumed by the target software.\n\n**Skills required.** - To identify and execute against an over-privileged system interface\n\n**Resources required.** Ability to communicate synchronously or asynchronously with server that publishes an over-privileged directory, program, or interface.

If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.\n\n**Prerequisites.** - The architecture under attack must publish or otherwise make available services that clients can attach to, either in an unauthenticated fashion, or having obtained an authentication token elsewhere. The service need not be 'discoverable', but in the event it isn't it must have some way of being discovered by an attacker. This might include listening on a well-known port. Ultimately, the likelihood of exploit depends on discoverability of the vulnerable service.\n\n**Skills required.** - A number of web service digging tools are available for free that help discover exposed web services and their interfaces. In the event that a web service is not listed, the attacker does not need to know much more in addition to the format of web service messages that they can sniff/monitor for.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.\n\n**Prerequisites.** - In order to feasibly execute this type of attack, some valuable data must be present in client software.\n- Additionally, this information must be unprotected, or protected in a flawed fashion, or through a mechanism that fails to resist reverse engineering, statistical, or other attack.\n\n**Skills required.** - The attacker must possess knowledge of client code structure as well as ability to reverse-engineer or decompile it or probe it in other ways. This knowledge is specific to the technology and language used for the client distribution\n\n**Resources required.** The attacker must possess access to the system or code being exploited. Such access, for this set of attacks, will likely be physical. The attacker will make use of reverse engineering technologies, perhaps for data or to extract functionality from the binary. Such tool use may be as simple as \"Strings\" or a hex editor. Removing functionality may require the use of only a hex editor, or may require aspects of the toolchain used to construct the application: for instance the Adobe Flash development environment.

An attacker modifies a known path on the target in order to reach material that is not available through intended channels. These attacks normally involve adding additional path separators (/ or \\) and/or dots (.), or encodings thereof, in various combinations in order to reach parent directories or entirely separate trees of the target's directory structure.\n\n**Prerequisites.** - The target application must accept a string as user input, fail to sanitize combinations of characters in the input that have a special meaning in the context of path navigation, and insert the user-supplied string into path navigation commands.\n\n**Skills required.** - To inject the malicious payload in a web page\n- To bypass non trivial filters in the application\n\n**Execution flow.** . ****: [Fingerprinting of the operating system] In order to perform a valid path traversal, the adversary needs to know what the underlying OS is so that the proper file seperator is used.\n. ****: [Survey application] Using manual or automated means, an adversary will survey the target application looking for all areas where user input is taken to specify a file name or path.\n. ****: [Attempt variations on input parameters] Using manual or automated means, an adversary attempts varying relative file path combinations on all found user input locations and observes the responses.\n. ****: [Access, modify, or execute arbitrary files.] An adversary injects path traversal syntax into identified vulnerable inputs to cause inappropriate reading, writing or execution of files.

This hostile service is created to deliver the correct content to the client software. For example, if the client-side application is a browser, the service will host a webpage that the browser loads.\n\n**Prerequisites.** - The targeted client software communicates with an external server.\n- The targeted client software has a buffer overflow vulnerability.\n\n**Skills required.** - To achieve a denial of service, an attacker can simply overflow a buffer by inserting a long string into an attacker-modifiable injection vector.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap requires a more in-depth knowledge and higher skill level.\n\n**Execution flow.** . ****: [Identify target client-side application] The adversary identifies a target client-side application to perform the buffer overflow on. The most common are browsers. If there is a known browser vulnerability an adversary could target that.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Create hostile service] The adversary creates a hostile service that will deliver content to the client-side application. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] Using the injection vector, the adversary delivers the content to the client-side application using the hostile service and overflows the buffer.\n\n**Mitigations.** - The client software should not install untrusted code from a non-authenticated server.\n- The client software should have the latest patches and should be audited for vulnerabilities before being used to communicate with potentially hostile servers.\n- Perform input validation for length of buffer inputs.

This is often done if there is a very large amount of information being collected or if information on earlier forms is used to pre-populate fields or determine which additional information the application needs to collect. An attacker who knows the names of the various forms in the sequence may be able to explicitly type in the name of a later form and navigate to it without first going through the previous forms. This can result in incomplete collection of information, incorrect assumptions about the information submitted by the attacker, or other problems that can impair the functioning of the application.\n\n**Prerequisites.** - The target must collect information from the user in a series of forms where each form has its own URL that the attacker can anticipate and the application must fail to detect attempts to access intermediate forms without first filling out the previous forms.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Related patterns.** - ChildOf: CAPEC-74\n\n**Underlying weaknesses.** - CWE-372 (Incomplete Internal State Distinction)\n\n## Reference: CAPEC-141 Cache Poisoning\n**CAPEC-141 Cache Poisoning (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: High\nAn attacker exploits the functionality of cache technologies to cause specific data to be cached that aids the attackers' objectives. This describes any attack whereby an attacker places incorrect or harmful material in cache. The targeted cache can be an application's cache (e.g. a web browser cache) or a public cache (e.g. a DNS or ARP cache). Until the cache is refreshed, most applications or clients will treat the corrupted cache value as valid. This can lead to a wide range of exploits including redirecting web browsers towards sites that install malware and repeatedly incorrect calculations based on the incorrect value.\n\n**Prerequisites.** - The attacker must be able to modify the value stored in a cache to match a desired value.\n- The targeted application must not be able to detect the illicit modification of the cache and must trust the cache value in its calculations.\n\n**Skills required.** - To overwrite/modify targeted cache\n\n**Execution flow.** . ****: [Identify and explore caches] Use tools to sniff traffic and scan a network in order to locate application's cache (e.g. a web browser cache) or a public cache (e.g. a DNS or ARP cache) that may have vulnerabilities. Look for poisoning point in cache table entries.\n. ****: [Cause specific data to be cached] An attacker sends bogus request to the target, and then floods responses that trick a cache to remember malicious responses, which are wrong answers of queries.\n. ****: [Redirect users to malicious website] As the attacker succeeds in exploiting the vulnerability, they are able to manipulate and interpose malicious response data to targeted victim queries.\n\n**Mitigations.** - Configuration: Disable client side caching.\n- Implementation: Listens for query replies on a network, and sends a notification via email when an entry changes.\n\n**Example instances.** - In this example, an attacker sends request to a local DNS server to look up www.example.com. The associated IP address of www.example.com is 1.3.5.7. […]\n\n## Reference: CAPEC-142 DNS Cache Poisoning\n**CAPEC-142 DNS Cache Poisoning (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nA domain name server translates a domain name (such as www.example.com) into an IP address that Internet hosts use to contact Internet resources. An adversary modifies a public DNS cache to cause certain names to resolve to incorrect addresses that the adversary specifies. The result is that client applications that rely upon the targeted cache for domain name resolution will be directed not to the actual address of the specified domain name but to some other address. Adversaries can use this to herd clients to sites that install malware on the victim's computer or to masquerade as part of a Pharming attack.\n\n**Prerequisites.** - A DNS cache must be vulnerable to some attack that allows the adversary to replace addresses in its lookup table.Client applications must trust the corrupted cashed values and utilize them for their domain name resolutions.\n\n**Skills required.** - To overwrite/modify targeted DNS cache\n\n**Resources required.** The adversary must have the resources to modify the targeted cache. In addition, in most cases the adversary will wish to host the sites to which users will be redirected, although in some cases redirecting to a third party site will accomplish the adversary's goals.\n\n**Execution flow.** . ****: [Explore resolver caches] Check DNS caches on local DNS server and client's browser with DNS cache enabled.\n. ****: [Attempt sending crafted records to DNS cache] A request is sent to the authoritative server for target website and wait for the iterative name resolver. An adversary sends bogus request to the DNS local server, and then floods responses that trick a DNS cache to remember malicious responses, which are wrong answers of DNS query.\n. ****: [Redirect users to malicious website] As the adversary succeeds in exploiting the vulnerability, the victim connects to a malicious site using a good web site's domain name.\n\n**Mitigations.** - Configuration: Make sure your DNS servers have been updated to the latest versions\n- Configuration: UNIX services like rlogin, rsh/rcp, xhost, and nfs are all susceptible to wrong information being held in a cache.

Fuzzing is a software security and functionality testing method that feeds randomly constructed input to the system and looks for an indication that a failure in response to that input has occurred. Fuzzing treats the system as a black box and is totally free from any preconceptions or assumptions about the system. Fuzzing can help an attacker discover certain assumptions made about user input in the system. Fuzzing gives an attacker a quick way of potentially uncovering some of these assumptions despite not necessarily knowing anything about the internals of the system. These assumptions can then be turned against the system by specially crafting user input that may allow an attacker to achieve their goals.\n\n**Skills required.** - There is a wide variety of fuzzing tools available.\n\n**Resources required.** Fuzzing tools.\n\n**Execution flow.** . ****: [Observe communication and inputs] The fuzzing attacker observes the target system looking for inputs and communications between modules, subsystems, or systems.\n. ****: [Generate fuzzed inputs] Given a fuzzing tool, a target input or protocol, and limits on time, complexity, and input variety, generate a list of inputs to try.

Email software has become increasingly sophisticated and feature-rich. In addition, email applications are ubiquitous and connected directly to the Web making them ideal targets to launch and propagate attacks. As the user demand for new functionality in email applications grows, they become more like browsers with complex rendering and plug in routines. As more email functionality is included and abstracted from the user, this creates opportunities for attackers. Virtually all email applications do not list email header information by default, however the email header contains valuable attacker vectors for the attacker to exploit particularly if the behavior of the email client application is known. Meta-characters are hidden from the user, but can contain scripts, enumerations, probes, and other attacks against the user's system.\n\n**Prerequisites.** - This attack targets most widely deployed feature rich email applications, including web based email programs.\n\n**Skills required.** - To distribute email\n\n**Execution flow.** . ****: [Identify and characterize metacharacter-processing vulnerabilities in email headers] An attacker creates emails with headers containing various metacharacter-based malicious payloads in order to determine whether the target application processes the malicious content and in what manner it does so.\n. ****: An attacker leverages vulnerabilities identified during the Experiment Phase to inject malicious email headers and cause the targeted email application to exhibit behavior outside of its expected constraints.\n\n**Mitigations.** - Design: Perform validation on email header data\n- Implementation: Implement email filtering solutions on mail server or on MTA, relay server.\n- Implementation: Mail servers that perform strict validation may catch these attacks, because metacharacters are not allowed in many header variables such as dns names\n\n**Consequences.** - None (None)\n\n**Example instances.** - Meta-characters are among the most valuable tools attackers have to deceive users into taking some action on their behalf.

This is an effective attack vector, because it can give an adversary physical access to network computers. It only takes a matter of seconds for someone to compromise a computer with physical access. One of the best technological tools at the disposal of a social engineer, posing as a technical support person, is a USB thumb drive. These are small, easy to conceal, and can be loaded with different payloads depending on what task needs to be done.

Email software has become increasingly sophisticated and feature-rich. In addition, email applications are ubiquitous and connected directly to the Web making them ideal targets to launch and propagate attacks. As the user demand for new functionality in email applications grows, they become more like browsers with complex rendering and plug in routines. As more email functionality is included and abstracted from the user, this creates opportunities for attackers. Virtually all email applications do not list email header information by default, however the email header contains valuable attacker vectors for the attacker to exploit particularly if the behavior of the email client application is known. Meta-characters are hidden from the user, but can contain scripts, enumerations, probes, and other attacks against the user's system.\n\n**Prerequisites.** - This attack targets most widely deployed feature rich email applications, including web based email programs.\n\n**Skills required.** - To distribute email\n\n**Execution flow.** . ****: [Identify and characterize metacharacter-processing vulnerabilities in email headers] An attacker creates emails with headers containing various metacharacter-based malicious payloads in order to determine whether the target application processes the malicious content and in what manner it does so.\n. ****: An attacker leverages vulnerabilities identified during the Experiment Phase to inject malicious email headers and cause the targeted email application to exhibit behavior outside of its expected constraints.\n\n**Mitigations.** - Design: Perform validation on email header data\n- Implementation: Implement email filtering solutions on mail server or on MTA, relay server.\n- Implementation: Mail servers that perform strict validation may catch these attacks, because metacharacters are not allowed in many header variables such as dns names\n\n**Consequences.** - None (None)\n\n**Example instances.** - Meta-characters are among the most valuable tools attackers have to deceive users into taking some action on their behalf.

This attack can return varied results depending upon the type of traceroute that is performed. Traceroute works by sending packets to a target while incrementing the Time-to-Live field in the packet header. As the packet traverses each hop along its way to the destination, its TTL expires generating an ICMP diagnostic message that identifies where the packet expired.

An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.\n\n**Prerequisites.** - The application must be navigable in a manner that associates elements (subsections) of the application with ACLs.\n- The various resources, or individual URLs, must be somehow discoverable by the attacker\n- The administrator must have forgotten to associate an ACL or has associated an inappropriately permissive ACL with a particular navigable resource.\n\n**Skills required.** - In order to discover unrestricted resources, the attacker does not need special tools or skills.

Once the adversary finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.\n\n**Prerequisites.** - The application uses environment variables.\n- An environment variable exposed to the user is vulnerable to a buffer overflow.\n- The vulnerable environment variable uses untrusted data.\n- Tainted data used in the environment variables is not properly validated. For instance boundary checking is not done before copying the input data to a buffer.\n\n**Skills required.** - An attacker can simply overflow a buffer by inserting a long string into an attacker-modifiable injection vector. The result can be a DoS.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap can require a higher skill level.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. In this attack the adversary looks for an application that loads the content of an environment variable into a buffer.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] Using the injection vector, the adversary injects the crafted overflow content into the buffer.\n\n**Mitigations.** - Do not expose environment variable to the user.\n- Do not use untrusted data in your environment variables.

Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.\n\n**Prerequisites.** - A web server that supports server side includes and has them enabled\n- User controllable input that can carry include directives to the web server\n\n**Skills required.** - The attacker needs to be aware of SSI technology, determine the nature of injection and be able to craft input that results in the SSI directives being executed.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. Determining whether the server supports SSI does not require special tools, and nor does injecting directives that get executed. Spidering tools can make the task of finding and following links easier.\n\n**Execution flow.** . ****: [Determine applicability] The adversary determines whether server side includes are enabled on the target web server.\n. ****: [Find Injection Point] Look for user controllable input, including HTTP headers, that can carry server side include directives to the web server.\n. ****: [Inject SSI] Using the found injection point, the adversary sends arbitrary code to be inlcuded by the application on the server side.

Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.\n\n**Prerequisites.** - An attacker and the victim are both using the same WiFi network.\n- The victim has an active session with a target system.\n- The victim is not using a secure channel to communicate with the target system (e.g. SSL, VPN, etc.)\n- The victim initiated communication with a target system that requires transfer of the session token or the target application uses AJAX and thereby periodically \"rings home\" asynchronously using the session token\n\n**Skills required.** - Easy to use tools exist to automate this attack.\n\n**Resources required.** A packet sniffing tool, such as wireshark, can be used to capture session information.\n\n**Execution flow.** . ****: [Detect Unprotected Session Token Transfer] The attacker sniffs on the wireless network to detect unencrypted traffic that contains session tokens.\n. ****: [Capture session token] The attacker uses sniffing tools to capture a session token from traffic.\n. ****: [Insert captured session token] The attacker attempts to insert a captured session token into communication with the targeted application to confirm viability for exploitation.\n. ****: [Session Token Exploitation] The attacker leverages the captured session token to interact with the targeted application in a malicious fashion, impersonating the victim.\n\n**Mitigations.** - Make sure that HTTPS is used to communicate with the target system.

One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.\n\n**Prerequisites.** - The target must be misconfigured to return a list of a directory's content when it receives a request that ends in a directory name rather than a file name.\n- The adversary must be able to control the path that is requested of the target.\n- The administrator must have failed to properly configure an ACL or has associated an overly permissive ACL with a particular directory.\n- The server version or patch level must not inherently prevent known directory listing attacks from working.\n\n**Skills required.** - To issue the request to URL without given a specific file name\n- To bypass the access control of the directory of listings\n\n**Resources required.** Ability to send HTTP requests to a web application.\n\n**Execution flow.** . ****: [Directory Discovery] Use a method, either manual, scripted, or automated to discover the directories on the server by making requests for directories that may possibly exist. During this phase the adversary is less concerned with whether a directory can be accessed or indexed and more focused on simply discovering what directories do exist on the target.\n. ****: [Iteratively explore directory/file structures] The adversary attempts to access the discovered directories that allow access and may attempt to bypass server or application level ACLs by using manual or automated methods\n. ****: [Read directories or files which are not intended for public viewing.] […]\n\n## Reference: CAPEC-128 Integer Attacks\n**CAPEC-128 Integer Attacks (full record).** Abstraction: Standard; Status: Draft; Severity: Medium; Likelihood: n/a\nAn attacker takes advantage of the structure of integer variables to cause these variables to assume values that are not expected by an application.

Hardware security mechanisms range from the use of computer case and cable locks as well as RFID tags for tracking computer assets. This layered approach makes it difficult for random physical security breaches to go unnoticed, but is less effective at stopping deliberate and carefully planned break-ins. Avoiding detection begins with evading building security and surveillance and methods for bypassing the electronic or physical locks which secure entry points.\n\n## Reference: CAPEC-391 Bypassing Physical Locks\n**CAPEC-391 Bypassing Physical Locks (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker uses techniques and methods to bypass physical security measures of a building or facility.

Lock Bumping is the use of a special type of key that can be tapped or bumped to cause the pins within the lock to fall into temporary alignment, allowing the lock to be opened. Lock bumping allows an attacker to open a lock without having the correct key. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate. A bump key is a specially constructed key that exploits this design. When the bump key is struck or firmly tapped, its teeth transfer the force of the tap into the key pins, causing the lock to momentarily shift into proper alignment for the mechanism to be opened.\n\n**Related patterns.** - ChildOf: CAPEC-391\n\n## Reference: CAPEC-393 Lock Picking\n**CAPEC-393 Lock Picking (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker uses lock picking tools and techniques to bypass the locks on a building or facility. Lock picking is the use of a special set of tools to manipulate the pins within a lock. Different sets of tools are required for each type of lock. Lock picking attacks have the advantage of being non-invasive in that if performed correctly the lock will not be damaged. A standard lock pin-and-tumbler lock is secured by a set of internal pins that prevent the tumbler device from turning. Spring loaded driver pins push down on the key pins preventing rotation so that the bolt remains in a locked position..

A Pick Gun is a special type of lock picking instrument that works on similar principles as lock bumping. A snap gun is a hand-held device with an attached metal pick. The metal pick strikes the pins within the lock, transferring motion from the key pins to the driver pins and forcing the lock into momentary alignment. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate. A Snap Gun exploits this design by using a metal pin to strike all of the key pins at once, forcing the driver pins to shift into an unlocked position. Unlike bump keys or lock picks, a Snap Gun may damage the lock more easily, leaving evidence that the lock has been tampered with.\n\n**Related patterns.** - ChildOf: CAPEC-391\n\n## Reference: CAPEC-395 Bypassing Electronic Locks and Access Controls\n**CAPEC-395 Bypassing Electronic Locks and Access Controls (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker exploits security assumptions to bypass electronic locks or other forms of access controls. Most attacks against electronic access controls follow similar methods but utilize different tools. Some electronic locks utilize magnetic strip cards, others employ RFID tags embedded within a card or badge, or may involve more sophisticated protections such as voice-print, thumb-print, or retinal biometrics. Magnetic Strip and RFID technologies are the most widespread because they are cost effective to deploy and more easily integrated with other electronic security measures.

Magstripe cards encode data on a band of iron-based magnetic particles arrayed in a stripe along a rectangular card. Most magstripe card data formats conform to ISO standards 7810, 7811, 7813, 8583, and 4909. The primary advantage of magstripe technology is ease of encoding and portability, but this also renders magnetic strip cards susceptible to unauthorized duplication. If magstripe cards are used for access control, all an attacker need do is obtain a valid card long enough to make a copy of the card and then return the card to its location (i.e. a co-worker's desk). Magstripe reader/writers are widely available as well as software for analyzing data encoded on the cards. By swiping a valid card, it becomes trivial to make any number of duplicates that function as the original."}]}

An attacker could send an e-mail to the victim's Gmail account (which ensures that the victim is logged in to Gmail when they receive it) with a link to the attackers' malicious site. If the victim clicked on the link, a request (containing the victim's authenticated session cookie) would be sent to the Gmail servers to fetch the victim's address book. This functionality is typically used by the Gmail service to get this data on the fly so that the user can be provided a list of contacts from which to choose the recipient of the e-mail. When the JSON object with the contacts came back, it was loaded into the JavaScript space via a script tag on the attackers' malicious page. Since the JSON object was never assigned to a local variable (which would have prevented a script from a different domain accessing it due to the browser's same origin policy), another mechanism was needed to access the data that it contained.

However, if the application only uses the name of the file when locating it, an attacker may be able to create a file with the same name and place it in a directory that the application will search before the directory with the legitimate file is searched.

Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An adversary can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the adversary can write to the program stack.\n\n**Prerequisites.** - The target application must accept a strings as user input, fail to sanitize string formatting characters in the user input, and process this string using functions that interpret string formatting characters.\n\n**Skills required.** - In order to discover format string vulnerabilities it takes only low skill, however, converting this discovery into a working exploit requires advanced knowledge on the part of the adversary.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Survey application] The adversary takes an inventory of the entry points of the application.\n. ****: [Determine user-controllable input susceptible to format string injection] Determine the user-controllable input susceptible to format string injection.

The solution is similar to protection against Cross Site Request Forger (CSRF), which is to use a hard to guess random nonce (that is unique to the victim's session with the server) that the attacker has no way of knowing (at least in the absence of other weaknesses). Each request from the client to the server should contain this nonce and the server should reject all requests that do not contain the nonce.\n- On the client side, the system's design could make it difficult to get access to the JSON object content via the script tag. Since the JSON object is never assigned locally to a variable, it cannot be readily modified by the attacker before being used by a script tag. For instance, if while(1) was added to the beginning of the JavaScript returned by the server, trying to access it with a script tag would result in an infinite loop. On the other hand, legitimate client side code can remove the while(1) statement after which the JavaScript can be evaluated.

This exploit relies on the target making multiples passes over the input data and processing a \"layer\" of special characters with each pass. In this manner, the attacker can disguise input that would otherwise be rejected as invalid by concealing it with layers of special/escape characters that are stripped off by subsequent processing steps. The goal is to first discover cases where the input validation layer executes before one or more parsing layers. That is, user input may go through the following logic in an application: <parser1> --> <input validator> --> <parser2>. In such cases, the attacker will need to provide input that will pass through the input validator, but after passing through parser2, will be converted into something that the input validator was supposed to stop.\n\n**Prerequisites.** - User input is used to construct a command to be executed on the target system or as part of the file name.\n- Multiple parser passes are performed on the data supplied by the user.\n\n**Skills required.** - Knowledge of various escaping schemes, such as URL escape encoding and XML escape characters.\n\n**Execution flow.** . ****: [Determine application/system inputs where bypassing input validation is desired] The attacker first needs to determine all of the application's/system's inputs where input validation is being performed and where they want to bypass it.\n. ****: [Determine which character encodings are accepted by the application/system] The attacker then needs to provide various character encodings to the application/system and determine which ones are accepted.

An attacker could send an e-mail to the victim's Gmail account (which ensures that the victim is logged in to Gmail when they receive it) with a link to the attackers' malicious site. If the victim clicked on the link, a request (containing the victim's authenticated session cookie) would be sent to the Gmail servers to fetch the victim's address book.

Among other things, they identify a particular participant, WSDL information for SOAP transactions, and supported communication protocols, including security protocols. By spoofing one of these messages an attacker could impersonate a legitimate business in a transaction or could manipulate the protocols used between a client and business. This could result in disclosure of sensitive information, loss of message integrity, or even financial fraud.\n\n**Prerequisites.** - The targeted business's UDDI or ebXML information must be served from a location that the attacker can spoof or compromise or the attacker must be able to intercept and modify unsecured UDDI/ebXML messages in transit.\n\n**Resources required.** The attacker must be able to force the target user to accept their spoofed UDDI or ebXML message as opposed to the a message associated with a legitimate company. Depending on the follow-on for the attack, the attacker may also need to serve its own web services.\n\n**Mitigations.** - Implementation: Clients should only trust UDDI, ebXML, or similar messages that are verifiably signed by a trusted party.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-345 (Insufficient Verification of Data Authenticity)\n\n## Reference: CAPEC-219 XML Routing Detour Attacks\n**CAPEC-219 XML Routing Detour Attacks (full record).** Abstraction: Standard; Status: Draft; Severity: Medium; Likelihood: High\nAn attacker subverts an intermediate system used to process XML content and forces the intermediate to modify and/or re-route the processing of the content. XML Routing Detour Attacks are Adversary in the Middle type attacks (CAPEC-94). The attacker compromises or inserts an intermediate system in the processing of the XML message. For example, WS-Routing can be used to specify a series of nodes or intermediaries through which content is passed. If any of the intermediate nodes in this route are compromised by an attacker they could be used for a routing detour attack. From the compromised system the attacker is able to route the XML process to other nodes of their choice and modify the responses so that the normal chain of processing is unaware of the interception. This system can forward the message to an outside entity and hide the forwarding and processing from the legitimate processing systems by altering the header information.\n\n**Prerequisites.** - The targeted system must have multiple stages processing of XML content.\n\n**Skills required.** - To inject a bogus node in the XML routing table\n\n**Resources required.** The attacker must be able to insert or compromise a system into the processing path for the transaction.\n\n**Execution flow.** . ****: [Survey the target] Using command line or an automated tool, an attacker records all instances of web services to process XML requests.\n. ****: [Identify SOAP messages that have multiple state processing.] Inspect instance to see whether the XML processing has multiple stages or not.\n. ****: [Launch an XML routing detour attack] The attacker injects a bogus routing node (using a WS-Referral service) into the routing table of the XML header of the SOAP message identified in the Explore phase. Thus, the attacker can route the XML message to the attacker controlled node (and access the message contents).\n\n**Mitigations.** - Design: Specify maximum number intermediate nodes for the request and require SSL connections with mutual authentication.\n- Implementation: Use SSL for connections between all parties with mutual authentication.

The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.\n\n**Prerequisites.** - Target client software must be a client that allows scripting communication from remote hosts, such as a JavaScript-enabled Web Browser.\n\n**Skills required.** - To achieve a redirection and use of less trusted source, an attacker can simply place a script in bulletin board, blog, wiki, or other user-generated content site that are echoed back to other client machines.\n- Exploiting a client side vulnerability to inject malicious scripts into the browser's executable process.\n\n**Resources required.** Ability to deploy a custom hostile service for access by targeted clients.

As a result, the user is directed to an adversary-controlled destination. TypoSquatting does not require an attack against the trusted domain or complicated reverse engineering.\n\n**Prerequisites.** - An adversary requires knowledge of popular or high traffic domains, that could be used to deceive potential targets.\n\n**Skills required.** - Adversaries must be able to register DNS hostnames/URL’s.\n\n**Execution flow.** . ****: [Determine target website] The adversary first determines which website to impersonate, generally one that is trusted and receives a consistent amount of traffic.\n. ****: [Impersonate trusted domain] In order to impersonate the trusted domain, the adversary needs to register the TypoSquatted URL.\n. ****: [Deceive user into visiting domain] Finally, the adversary needs to deceive a user into visiting the TypoSquatted domain.\n\n**Mitigations.** - Authenticate all servers and perform redundant checks when using DNS hostnames.\n- Purchase potential TypoSquatted domains and forward to legitimate domain.\n\n**Consequences.** - None (None)\n\n**Example instances.** - An adversary sends an email, impersonating paypal.com, to a user stating that they have just received a money transfer and to click the given link to obtain their money.\n- However, the link the in email is paypa1.com instead of paypal.com, which the user clicks without fully reading the link.\n- The user is directed to the adversary's website, which appears as if it is the legitimate paypal.com login page.\n- The user thinks they are logging into their account, but have actually just given their paypal credentials to the adversary.

The attack here is similar to plain SQL injection, except that the application does not use JDBC to directly talk to the database, but instead it uses a data access layer generated by an ORM tool or framework (e.g. Hibernate). While most of the time code generated by an ORM tool contains safe access methods that are immune to SQL injection, sometimes either due to some weakness in the generated code or due to the fact that the developer failed to use the generated access methods properly, SQL injection is still possible.\n\n**Prerequisites.** - An application uses data access layer generated by an ORM tool or framework\n- An application uses user supplied data in queries executed against the database\n- The separation between data plane and control plane is not ensured, through either developer error or an underlying weakness in the data access layer code generation framework\n\n**Skills required.** - Knowledge of general SQL injection techniques and subtleties of the ORM framework is needed\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Determine Persistence Framework Used] An attacker tries to determine what persistence framework is used by the application in order to leverage a weakness in the generated data access layer code or a weakness in a way that the data access layer may have been used by the developer.\n. ****: [Probe for ORM Injection vulnerabilities] The attacker injects ORM syntax into user-controllable data inputs of the application to determine if it is possible modify data query structure and content.\n.

Because different file types are handled by different server processes, misclassification may force the Web server to take unexpected action, or expected actions in an unexpected sequence. This may cause the server to exhaust resources, supply debug or system data to the attacker, or bind an attacker to a remote process.\n\n**Prerequisites.** - Web server software must rely on file name or file extension for processing.\n- The attacker must be able to make HTTP requests to the web server.\n\n**Skills required.** - To modify file name or file extension\n- To use misclassification to force the Web server to disclose configuration information, source, or binary data\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Footprint file input vectors] Manually or using an automated tool, an attacker searches for all input locations where a user has control over the filenames or MIME types of files submitted to the web server.\n. ****: [File misclassification shotgunning] An attacker makes changes to file extensions and MIME types typically processed by web servers and looks for abnormal behavior.\n. ****: [File misclassification sniping] Understanding how certain file types are processed by web servers, an attacker crafts varying file payloads and modifies their file extension or MIME type to be that of the targeted type to see if the web server is vulnerable to misclassification of that type.\n. ****: [Disclose information] The attacker, by manipulating a file extension or MIME type is able to make the web server return raw information (not executed).\n\n**Mitigations.** - Implementation: Server routines should be determined by content not determined by filename or file extension.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Example instances.** - J2EE application servers are supposed to execute Java Server Pages (JSP).

On the service provider side, the SOAP message is parsed and parameters are not properly validated before being used to access a database in a way that does not use parameter binding, thus enabling the attacker to control the structure of the executed SQL query. This pattern describes a SQL injection attack with the delivery mechanism being a SOAP message.\n\n**Prerequisites.** - SOAP messages are used as a communication mechanism in the system\n- SOAP parameters are not properly validated at the service provider\n- The service provider does not properly utilize parameter binding when building SQL queries\n\n**Skills required.** - If the attacker is able to gain good understanding of the system's database schema\n- If the attacker has to perform Blind SQL Injection\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Detect Incorrect SOAP Parameter Handling] The attacker tampers with the SOAP message parameters and looks for indications that the tampering caused a change in behavior of the targeted application.\n. ****: [Probe for SQL Injection vulnerability] The attacker injects SQL syntax into vulnerable SOAP parameters identified during the Explore phase to search for unfiltered execution of the SQL syntax in a query.\n. ****: [Inject SQL via SOAP Parameters] The attacker injects SQL via SOAP parameters identified as vulnerable during Explore phase to launch a first or second order SQL injection attack.\n\n**Mitigations.** - Properly validate and sanitize/reject user input at the service provider.\n- Ensure that prepared statements or other mechanism that enables parameter binding is used when accessing the database in a way that would prevent the attackers' supplied data from controlling the structure of the executed query.\n- At the database level, ensure that the database user used by the application in a particular context has the minimum needed privileges to the database that are needed to perform the operation.

The malicious activity is then used to mimic the trusted activity's user interface and prompt the target to enter sensitive data as if they were interacting with the trusted activity.\n\n**Prerequisites.** - The adversary must have previously installed the malicious application onto the Android device that will run in place of the trusted activity.\n\n**Skills required.** - The adversary must typically overcome network and host defenses in order to place malware on the system.\n\n**Resources required.** Malware capable of acting on the adversary's objectives.\n\n**Execution flow.** . ****: [Find an android application that uses implicit intents] Since this attack only works on android applications that use implicit intents, rather than explicit intents, an adversary must first identify an app that uses implicit intents to launch an Android-based trusted activity, and what that activity is.\n. ****: [Create a malicious app] The adversary must create a malicious android app meant to intercept implicit intents to launch an Adroid-based trusted activity.

When the user enters sensitive information it will be captured by the malicious app.\n\n**Mitigations.** - To mitigate this type of an attack, explicit intents should be used whenever sensitive data is being sent. An 'explicit intent' is delivered to a specific application as declared within the intent, whereas an 'implicit intent' is directed to an application as defined by the Android operating system.

Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application will be used to issue spoofed intents.\n\n**Mitigations.** - To limit one's exposure to this type of attack, developers should avoid exporting components unless the component is specifically designed to handle requests from untrusted applications. Developers should be aware that declaring an intent filter will automatically export the component, exposing it to public access. Critical, state-changing actions should not be placed in exported components. If a single component handles both interand intra-application requests, the developer should consider dividing that component into separate components. If a component must be exported (e.g., to receive system broadcasts), then the component should dynamically check the caller's identity prior to performing any operations. Requiring Signature or SignatureOrSystem permissions is an effective way of limiting a component's exposure to a set of trusted applications. Finally, the return values of exported components can also leak private data, so developers should check the caller's identity prior to returning sensitive values.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)\n\n## Reference: CAPEC-503 WebView Exposure\n**CAPEC-503 WebView Exposure (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API.

Once loaded, the malicious web page will have the same permissions as the target application and will have access to all registered interfaces. Both the permission and the interface must be in place for the functionality to be exposed.\n\n**Mitigations.** - To mitigate this type of an attack, an application should limit permissions to only those required and should verify the origin of all web content it loads.\n\n**Related patterns.** - ChildOf: CAPEC-122\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)\n\n## Reference: CAPEC-504 Task Impersonation\n**CAPEC-504 Task Impersonation (full record).** Abstraction: Standard; Status: Stable; Severity: High; Likelihood: Medium\nAn adversary, through a previously installed malicious application, impersonates an expected or routine task in an attempt to steal sensitive information or leverage a user's privileges.\n\n**Prerequisites.** - The adversary must already have access to the target system via some means.\n- A legitimate task must exist that an adversary can impersonate to glean credentials.\n- The user's privileges allow them to execute certain tasks with elevated privileges.\n\n**Skills required.** - Once an adversary has gained access to the target system, impersonating a task is trivial.\n\n**Resources required.** Malware or some other means to initially comprise the target system.

Thereafter, messages intended for the target application are handled by the malicious application. Upon receiving a message, the malicious application displays a screen that mimics the target application, thereby convincing the user to enter sensitive information. This type of attack is most often used to obtain sensitive information (e.g., credentials) from the user as they think that they are interacting with the intended target application.\n\n**Mitigations.** - The only known mitigation to this attack is to avoid installing the malicious application on the device.

This is often accomplished by overlaying one screen on top of another while giving the appearance of a single interface. There are two main techniques used to accomplish this. The first is to leverage transparent properties that allow taps on the screen to pass through the visible application to an application running in the background. The second is to strategically place a small object (e.g., a button or text field) on top of the visible screen and make it appear to be a part of the underlying application. In both cases, the user is convinced to tap on the screen but does not realize the application that they are interacting with.\n\n**Prerequisites.** - This pattern of attack requires the ability to execute a malicious application on the user's device.

Spear Phishing is an enhanced version of the Phishing attack targeted to a specific user or group. The quality of the targeted email is usually enhanced by appearing to come from a known or trusted entity. If the email account of some trusted entity has been compromised the message may be digitally signed. The message will contain information specific to the targeted users that will enhance the probability that they will follow the URL to the compromised site. For example, the message may indicate knowledge of the targets employment, residence, interests, or other information that suggests familiarity. As soon as the user follows the instructions in the message, the attack proceeds as a standard Phishing attack.\n\n**Prerequisites.** - None. Any user can be targeted by a Spear Phishing attack.\n\n**Skills required.** - Spear phishing attacks require specific knowledge of the victims being targeted, such as which bank is being used by the victims, or websites they commonly log into (Google, Facebook, etc).\n\n**Resources required.** An adversay must have the ability communicate their phishing scheme to the victims (via email, instance message, etc.), as well as a website or other platform for victims to enter personal information into.\n\n**Execution flow.** . ****: [Obtain useful contextual detailed information about the targeted user or organization] An adversary collects useful contextual detailed information about the targeted user or organization in order to craft a more deceptive and enticing message to lure the target into responding.\n. ****: [Optional: Obtain domain name and certificate to spoof legitimate site] This optional step can be used to help the adversary impersonate the legitimate site more convincingly.

Attackers use this class of attacks to cause applications to enter unstable states, overwrite or expose sensitive information, and even execute arbitrary code with the application's privileges. This class of attacks differs from attacks on configuration information (even if file-based) in that file manipulation causes the file processing to result in non-standard behaviors, such as buffer overflows or use of the incorrect interpreter. Configuration attacks rely on the application interpreting files correctly in order to insert harmful configuration information. Likewise, resource location attacks rely on controlling an application's ability to locate files, whereas File Manipulation attacks do not require the application to look in a non-default location, although the two classes of attacks are often combined.\n\n**Prerequisites.** - The target must use the affected file without verifying its integrity.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

Any transmission medium can theoretically be sniffed if the adversary can examine the contents between the sender and recipient. Sniffing Attacks are similar to Adversary-In-The-Middle attacks (CAPEC-94), but are entirely passive. AiTM attacks are predominantly active and often alter the content of the communications themselves.\n\n**Prerequisites.** - The target data stream must be transmitted on a medium to which the adversary has access.\n\n**Resources required.** The adversary must be able to intercept the transmissions containing the data of interest.

This pattern of attack allows the adversary to compromise the application or server via the execution of unauthorized code. An application typically makes calls to functions that are a part of libraries external to the application. These libraries may be part of the operating system or they may be third party libraries. If an adversary can redirect an application's attempts to access these libraries to other libraries that the adversary supplies, the adversary will be able to force the targeted application to execute arbitrary code. This is especially dangerous if the targeted application has enhanced privileges.

Methods that take scripted instructions (or references to scripted instructions) can be very flexible and powerful. However, if an attacker can specify the script that serves as input to these methods they can gain access to a great deal of functionality.

Once the adversary finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.\n\n**Prerequisites.** - The application uses environment variables.\n- An environment variable exposed to the user is vulnerable to a buffer overflow.\n- The vulnerable environment variable uses untrusted data.\n- Tainted data used in the environment variables is not properly validated. For instance boundary checking is not done before copying the input data to a buffer.\n\n**Skills required.** - An attacker can simply overflow a buffer by inserting a long string into an attacker-modifiable injection vector. The result can be a DoS.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap can require a higher skill level.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. In this attack the adversary looks for an application that loads the content of an environment variable into a buffer.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] Using the injection vector, the adversary injects the crafted overflow content into the buffer.\n\n**Mitigations.** - Do not expose environment variable to the user.\n- Do not use untrusted data in your environment variables.

As a consequence, an adversary is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the adversaries' choice.\n\n**Prerequisites.** - Targeted software performs buffer operations.\n- Targeted software inadequately performs bounds-checking on buffer operations.\n- Adversary has the capability to influence the input to buffer operations.\n\n**Skills required.** - In most cases, overflowing a buffer does not require advanced skills beyond the ability to notice an overflow and stuff an input variable with content.\n- In cases of directed overflows, where the motive is to divert the flow of the program or application as per the adversaries' bidding, high level skills are required. This may involve detailed knowledge of the target system architecture and kernel.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. Detecting and exploiting a buffer overflow does not require any resources beyond knowledge of and access to the target system.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on.

Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.\n\n**Prerequisites.** - A web server that supports server side includes and has them enabled\n- User controllable input that can carry include directives to the web server\n\n**Skills required.** - The attacker needs to be aware of SSI technology, determine the nature of injection and be able to craft input that results in the SSI directives being executed.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. Determining whether the server supports SSI does not require special tools, and nor does injecting directives that get executed.

When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.\n\n**Prerequisites.** - The attacker must have the ability to modify non-executable files consumed by the target software.\n\n**Skills required.** - To identify and execute against an over-privileged system interface\n\n**Resources required.** Ability to communicate synchronously or asynchronously with server that publishes an over-privileged directory, program, or interface.

If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.\n\n**Prerequisites.** - The architecture under attack must publish or otherwise make available services that clients can attach to, either in an unauthenticated fashion, or having obtained an authentication token elsewhere. The service need not be 'discoverable', but in the event it isn't it must have some way of being discovered by an attacker. This might include listening on a well-known port. Ultimately, the likelihood of exploit depends on discoverability of the vulnerable service.\n\n**Skills required.** - A number of web service digging tools are available for free that help discover exposed web services and their interfaces.

This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.\n\n**Prerequisites.** - In order to feasibly execute this type of attack, some valuable data must be present in client software.\n- Additionally, this information must be unprotected, or protected in a flawed fashion, or through a mechanism that fails to resist reverse engineering, statistical, or other attack.\n\n**Skills required.** - The attacker must possess knowledge of client code structure as well as ability to reverse-engineer or decompile it or probe it in other ways. This knowledge is specific to the technology and language used for the client distribution\n\n**Resources required.** The attacker must possess access to the system or code being exploited. Such access, for this set of attacks, will likely be physical. The attacker will make use of reverse engineering technologies, perhaps for data or to extract functionality from the binary. Such tool use may be as simple as \"Strings\" or a hex editor. Removing functionality may require the use of only a hex editor, or may require aspects of the toolchain used to construct the application: for instance the Adobe Flash development environment.

Some filters fail to recognize dangerous sequences if they are preceded by repeated characters. For example, by doubling the < before a script command, (<<script or %3C%3script using URI encoding) the filters of some web applications may fail to recognize the presence of a script tag.

The service need not be 'discoverable', but in the event it isn't it must have some way of being discovered by an attacker. This might include listening on a well-known port. Ultimately, the likelihood of exploit depends on discoverability of the vulnerable service.\n\n**Skills required.** - A number of web service digging tools are available for free that help discover exposed web services and their interfaces.

Such access, for this set of attacks, will likely be physical. The attacker will make use of reverse engineering technologies, perhaps for data or to extract functionality from the binary. Such tool use may be as simple as \"Strings\" or a hex editor.

An attacker can create a Symlink link to a target file not otherwise accessible to them. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link.

This can be setup with rules to block IP addresses found in IP reputation databases, which contains lists of known bad IP addresses. Analysts should also monitor when the traffic flow becomes abnormally large, and be able to add on-the-fly rules to block malicious traffic.

A good password throttling mechanism will make it almost impossible computationally to brute force a password as it may either lock out the user after a certain number of incorrect attempts or introduce time out periods. Both of these would make a brute force attack impractical.\n\n**Skills required.** - A brute force attack is very straightforward. A variety of password cracking tools are widely available.\n\n**Resources required.** A powerful enough computer for the job with sufficient CPU, RAM and HD.

Because the attackers' file is discovered first, it would be used by the target application. This attack can be extremely destructive if the referenced file is executable and/or is granted special privileges based solely on having a particular name.\n\n**Prerequisites.** - The target application must include external files. Most non-trivial applications meet this criterion.\n- The target application does not verify that a located file is the one it was looking for through means other than the name. Many applications fail to perform checks of this type.\n- The directories the target application searches to find the included file include directories writable by the attacker which are searched before the protected directory containing the actual files. It is much less common for applications to meet this criterion, but if an attacker can manipulate the application's search path (possibly by controlling environmental variables) then they can force this criterion to be met.\n\n**Resources required.** The attacker must have sufficient access to place an arbitrarily named file somewhere early in the application's search path.\n\n**Related patterns.** - ChildOf: CAPEC-17\n\n**Underlying weaknesses.** - CWE-706 (Use of Incorrectly-Resolved Name or Reference)\n\n**ATT&CK mapping.** - 1036 (Masquerading)"}]}

The result is often a denial of service caused by the application being unable to process the corrupted file, but other results, including the disabling of filters or access controls (if the application fails in an unsafe way rather than failing by locking down) or buffer overflows are possible.\n\n**Prerequisites.** - The targeted application must utilize a configuration file that an attacker is able to corrupt. In some cases, the attacker must be able to force the (re-)reading of the corrupted file if the file is normally only consulted at startup.\n- The severity of the attack hinges on how the application responds to the corrupted file. If the application detects the corruption and locks down, this may result in the denial of services provided by the application. If the application fails to detect the corruption, the result could be a more severe denial of service (crash or hang) or even an exploitable buffer overflow. If the application detects the corruption but fails in an unsafe way, this attack could result in the continuation of services but without certain security structures, such as filters or access controls. For example, if the corrupted file configures filters, an unsafe response from an application could result in simply disabling the filtering mechanisms due to the lack of usable configuration data.\n\n**Resources required.** This varies depending on the resources necessary to corrupt the configuration file and the resources needed to force the application to re-read it (if any).\n\n**Related patterns.** - ChildOf: CAPEC-17\n\n**Underlying weaknesses.** - CWE-829 (Inclusion of Functionality from Untrusted Control Sphere)"}]}

Tracerouting can allow the adversary to construct a working topology of systems and routers by listing the systems through which data passes through on their way to the targeted machine. This attack can return varied results depending upon the type of traceroute that is performed. Traceroute works by sending packets to a target while incrementing the Time-to-Live field in the packet header. As the packet traverses each hop along its way to the destination, its TTL expires generating an ICMP diagnostic message that identifies where the packet expired. Traditional techniques for tracerouting involved the use of ICMP and UDP, but as more firewalls began to filter ingress ICMP, methods of traceroute using TCP were developed.\n\n**Prerequisites.** - A network capable of routing the attackers' packets to the destination network.\n\n**Resources required.** A command line version of traceroute or similar tool that performs route enumeration.\n\n**Consequences.** - None (None)\n\n**Related patterns.** - ChildOf: CAPEC-309\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n\n## Reference: CAPEC-294 ICMP Address Mask Request\n**CAPEC-294 ICMP Address Mask Request (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary sends an ICMP Type 17 Address Mask Request to gather information about a target's networking configuration.

Lock Bumping is the use of a special type of key that can be tapped or bumped to cause the pins within the lock to fall into temporary alignment, allowing the lock to be opened. Lock bumping allows an attacker to open a lock without having the correct key. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate.

A Pick Gun is a special type of lock picking instrument that works on similar principles as lock bumping. A snap gun is a hand-held device with an attached metal pick. The metal pick strikes the pins within the lock, transferring motion from the key pins to the driver pins and forcing the lock into momentary alignment. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate. A Snap Gun exploits this design by using a metal pin to strike all of the key pins at once, forcing the driver pins to shift into an unlocked position.

Some electronic locks utilize magnetic strip cards, others employ RFID tags embedded within a card or badge, or may involve more sophisticated protections such as voice-print, thumb-print, or retinal biometrics. Magnetic Strip and RFID technologies are the most widespread because they are cost effective to deploy and more easily integrated with other electronic security measures.

Magstripe cards encode data on a band of iron-based magnetic particles arrayed in a stripe along a rectangular card. Most magstripe card data formats conform to ISO standards 7810, 7811, 7813, 8583, and 4909. The primary advantage of magstripe technology is ease of encoding and portability, but this also renders magnetic strip cards susceptible to unauthorized duplication. If magstripe cards are used for access control, all an attacker need do is obtain a valid card long enough to make a copy of the card and then return the card to its location (i.e. a co-worker's desk). Magstripe reader/writers are widely available as well as software for analyzing data encoded on the cards.

This may require prior access to the machine on which the target application runs. If the cache is encrypted, the attacker would need sufficient computational resources to crack the encryption. With strong encryption schemes, doing this could be intractable, but weaker encryption schemes could allow an attacker with sufficient resources to read the file.\n\n## Defensive use\nEach precondition is a control point: remove it and the pattern fails.\n\n## Reference: CAPEC-102 Session Sidejacking\n**CAPEC-102 Session Sidejacking (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nSession sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.\n\n**Prerequisites.** - An attacker and the victim are both using the same WiFi network.\n- The victim has an active session with a target system.\n- The victim is not using a secure channel to communicate with the target system (e.g. SSL, VPN, etc.)\n- The victim initiated communication with a target system that requires transfer of the session token or the target application uses AJAX and thereby periodically \"rings home\" asynchronously using the session token\n\n**Skills required.** - Easy to use tools exist to automate this attack.\n\n**Resources required.** A packet sniffing tool, such as wireshark, can be used to capture session information.\n\n**Execution flow.** . ****: [Detect Unprotected Session Token Transfer] The attacker sniffs on the wireless network to detect unencrypted traffic that contains session tokens.\n. ****: [Capture session token] The attacker uses sniffing tools to capture a session token from traffic.\n. ****: [Insert captured session token] The attacker attempts to insert a captured session token into communication with the targeted application to confirm viability for exploitation.\n. ****: [Session Token Exploitation] The attacker leverages the captured session token to interact with the targeted application in a malicious fashion, impersonating the victim.\n\n**Mitigations.** - Make sure that HTTPS is used to communicate with the target system. Alternatively, use VPN if possible.

[…]\n\n## Reference: CAPEC-104 Cross Zone Scripting\n**CAPEC-104 Cross Zone Scripting (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: Medium\nAn attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security.\n\n**Prerequisites.** - The target must be using a zone-aware browser.\n\n**Skills required.** - Ability to craft malicious scripts or find them elsewhere and ability to identify functionality that is running web controls in the local zone and to find an injection vector into that functionality\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Find systems susceptible to the attack] Find systems that contain functionality that is accessed from both the internet zone and the local zone. There needs to be a way to supply input to that functionality from the internet zone and that original input needs to be used later on a page from a local zone.\n. ****: [Find the insertion point for the payload] The attacker first needs to find some system functionality or possibly another weakness in the system (e.g. susceptibility to cross site scripting) that would provide the attacker with a mechanism to deliver the payload (i.e. the code to be executed) to the user. The location from which this code is executed in the user's browser needs to be within the local machine zone.\n. ****: [Craft and inject the payload] Develop the payload to be executed in the higher privileged zone in the user's browser. Inject the payload and attempt to lure the victim (if possible) into executing the functionality which unleashes the payload.\n\n**Mitigations.** - Disable script execution.

Data copied to the clipboard can be accessed by other applications, such as malware built to exfiltrate or log clipboard contents on a periodic basis. In this way, the adversary aims to garner information to which they are unauthorized.\n\n**Prerequisites.** - The adversary must have a means (i.e., a pre-installed tool or background process) by which to collect data from the clipboard and store it.

Conducting this type of attack entails the adversary infecting the target with firmware altering malware, using known tools, and a payload. Once this malware is executed, the MBR is modified to include instructions to execute the payload at desired intervals and when the system is booted up. A successful attack will obtain persistence within the victim system even if the operating system is reinstalled and/or if the component is formatted or has its data erased.\n\n**Prerequisites.** - Advanced knowledge about the target component's firmware\n- Advanced knowledge about Master Boot Records (MBR)\n- Advanced knowledge about tools used to insert firmware altering malware.\n- Advanced knowledge about component shipments to the target organization.\n\n**Skills required.** - Ability to access and reverse engineer hardware component firmware.\n- Ability to intercept components in transit.\n- Ability to create malicious payload to be executed from MBR.\n- Ability to leverage known malware tools to infect target system and insert firmware altering malware/payload\n\n**Resources required.** Manufacturer source code for hardware components.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n**Prerequisites.** - The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Skills required.** - An attacker can try special characters in the URL and bypass the URL validation.\n- The attacker may write a script to defeat the input filtering mechanism.\n\n**Execution flow.** . ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL. The attacker find out that some characters are not filtered properly.\n. ****: The attacker crafts a malicious URL string request and sends it to the server.\n. ****: The server decodes and interprets the URL string. Unfortunately since the input filtering is not done properly, the special characters have harmful consequences.\n\n**Mitigations.** - Assume all input is malicious. Create an allowlist that defines all valid input to the software system based on the requirements specifications. Input that does not match against the allowlist should not be permitted to enter into the system. […]"}]}

However, if the application only uses the name of the file when locating it, an attacker may be able to create a file with the same name and place it in a directory that the application will search before the directory with the legitimate file is searched. Because the attackers' file is discovered first, it would be used by the target application. This attack can be extremely destructive if the referenced file is executable and/or is granted special privileges based solely on having a particular name.\n\n**Prerequisites.** - The target application must include external files. Most non-trivial applications meet this criterion.\n- The target application does not verify that a located file is the one it was looking for through means other than the name. Many applications fail to perform checks of this type.\n- The directories the target application searches to find the included file include directories writable by the attacker which are searched before the protected directory containing the actual files. It is much less common for applications to meet this criterion, but if an attacker can manipulate the application's search path (possibly by controlling environmental variables) then they can force this criterion to be met.\n\n**Resources required.** The attacker must have sufficient access to place an arbitrarily named file somewhere early in the application's search path.\n\n**Related patterns.** - ChildOf: CAPEC-17\n\n**Underlying weaknesses.** - CWE-706 (Use of Incorrectly-Resolved Name or Reference)\n\n**ATT&CK mapping.** - 1036 (Masquerading)"}]}

An attacker can create a Symlink link to a target file not otherwise accessible to them. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file they will be writing to the sensitive file by using the Symlink.

This can allow the adversary to bypass access control and/or execute functionality not intended by the interface implementation, possibly compromising the system which integrates the interface. Interface manipulation can take on a number of forms including forcing the unexpected use of an interface or the use of an interface in an unintended way.\n\n**Prerequisites.** - The target system must expose interface functionality in a manner that can be discovered and manipulated by an adversary. This may require reverse engineering the interface or decrypting/de-obfuscating client-server exchanges.\n\n**Resources required.** The requirements vary depending upon the nature of the interface. For example, application-layer APIs related to the processing of the HTTP protocol may require one or more of the following: an Adversary-In-The-Middle (CAPEC-94) proxy, a web browser, or a programming/scripting language.\n\n**Underlying weaknesses.** - CWE-1192 (Improper Identifier for IP Block used in System-On-Chip (SOC))\n\n## Reference: CAPEC-114 Authentication Abuse\n**CAPEC-114 Authentication Abuse (full record).** Abstraction: Meta; Status: Draft; Severity: Medium; Likelihood: n/a\nAn attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation.

Hardware security mechanisms range from the use of computer case and cable locks as well as RFID tags for tracking computer assets. This layered approach makes it difficult for random physical security breaches to go unnoticed, but is less effective at stopping deliberate and carefully planned break-ins. Avoiding detection begins with evading building security and surveillance and methods for bypassing the electronic or physical locks which secure entry points.\n\n## Reference: CAPEC-391 Bypassing Physical Locks\n**CAPEC-391 Bypassing Physical Locks (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker uses techniques and methods to bypass physical security measures of a building or facility. Physical locks may range from traditional lock and key mechanisms, cable locks used to secure laptops or servers, locks on server cases, or other such devices. Techniques such as lock bumping, lock forcing via snap guns, or lock picking can be employed to bypass those locks and gain access to the facilities or devices they protect, although stealth, evidence of tampering, and the integrity of the lock following an attack, are considerations that may determine the method employed. Physical locks are limited by the complexity of the locking mechanism. While some locks may offer protections such as shock resistant foam to prevent bumping or lock forcing methods, many commonly employed locks offer no such countermeasures.\n\n**Related patterns.** - ChildOf: CAPEC-390\n\n## Reference: CAPEC-392 Lock Bumping\n**CAPEC-392 Lock Bumping (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker uses a bump key to force a lock on a building or facility and gain entry. Lock Bumping is the use of a special type of key that can be tapped or bumped to cause the pins within the lock to fall into temporary alignment, allowing the lock to be opened. Lock bumping allows an attacker to open a lock without having the correct key. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate. A bump key is a specially constructed key that exploits this design. When the bump key is struck or firmly tapped, its teeth transfer the force of the tap into the key pins, causing the lock to momentarily shift into proper alignment for the mechanism to be opened."}]}

By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.\n\n**Prerequisites.** - This pattern of attack requires a temporal aspect to the servicing of a given request. Success can be achieved if the adversary can make requests that collectively take more time to complete than legitimate user requests within the same time frame.\n\n**Resources required.** To successfully execute this pattern of attack, a script or program is often required that is capable of continually engaging the target and maintaining sustained usage of a specific resource. Depending on the configuration of the target, it may or may not be necessary to involve a network or cluster of objects all capable of making parallel requests.\n\n**Mitigations.** - Potential mitigations include requiring a unique login for each resource request, constraining local unprivileged access by disallowing simultaneous engagements of the resource, or limiting access to the resource to one access per IP address. In such scenarios, the adversary would have to increase engagements either by launching multiple sessions manually or programmatically to counter such defenses.\n\n**Underlying weaknesses.** - CWE-400 (Uncontrolled Resource Consumption)\n\n**ATT&CK mapping.** - 1499 (Endpoint Denial of Service)\n\n## Reference: CAPEC-228 DTD Injection\n**CAPEC-228 DTD Injection (full record).** Abstraction: Detailed; Status: Draft; Severity: Medium; Likelihood: n/a\nAn attacker injects malicious content into an application's DTD in an attempt to produce a negative technical impact.

Magstripe reader/writers are widely available as well as software for analyzing data encoded on the cards. By swiping a valid card, it becomes trivial to make any number of duplicates that function as the original.\n\n**Related patterns.** - ChildOf: CAPEC-395\n\n## Reference: CAPEC-398 Magnetic Strip Card Brute Force Attacks\n**CAPEC-398 Magnetic Strip Card Brute Force Attacks (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary analyzes the data on two or more magnetic strip cards and is able to generate new cards containing valid sequences that allow unauthorized access and/or impersonation of individuals.\n\n**Prerequisites.** - The ability to calculate a card checksum and write out a valid checksum value.

In some cases RFID chips are used for building access control, employee identification, or as markers on products being delivered along a supply chain. Some organizations also embed RFID tags inside computer assets to trigger alarms if they are removed from particular rooms, zones, or buildings.

The adversary will also attempt to access the application through an alternate IP address encoding to see if access control changes\n. ****: [Bypass access control] Using an alternate IP address encoding, the adversary will either access the application or give the alternate encoding as input, bypassing access control restrictions.\n\n**Mitigations.** - Design: Default deny access control policies\n- Design: Input validation routines should check and enforce both input data types and content against a positive specification. In regards to IP addresses, this should include the authorized manner for the application to represent IP addresses and not accept user specified IP addresses and IP address formats (such as ranges)\n- Implementation: Perform input validation for all remote content.

ATA Security is often employed to protect hard disk information from unauthorized access. The mechanism requires the user to type in a password before the BIOS is allowed access to drive contents. Some implementations of ATA security will accept the ATA command to update the password without the user having authenticated with the BIOS. This occurs because the security mechanism assumes the user has first authenticated via the BIOS prior to sending commands to the drive. Various methods exist for exploiting this flaw, the most common being installing the ATA protected drive into a system lacking ATA security features (a.k.a. hot swapping). Once the drive is installed into the new system the BIOS can be used to reset the drive password.\n\n**Prerequisites.** - Access to the system containing the ATA Drive so that the drive can be physically removed from the system.\n\n**Mitigations.** - Avoid using ATA password security when possible.\n- Use full disk encryption to protect the entire contents of the drive or sensitive partitions on the drive.\n- Leverage third-party utilities that interface with self-encrypting drives (SEDs) to provide authentication, while relying on the SED itself for data encryption.\n\n**Example instances.** - The A-FF Repair Station tool is a data recovery utility that can be used for ATA password removal (both High and Maximum level) and firmware area recovery. An adversary with access to this tool could reset the ATA password to bypass this security feature and unlock the hard drive. The adversary could then obtain any data contained within the drive. [REF-702]\n- An adversary gains physical access to the targeted hard drive and installs it into a system that does not support ATA security features. Once the drive is installed in the feature-lacking system, the adversary is able to reset the hard drive password via the BIOS. As a result, the adversary is able to bypass ATA password security and access content on the drive."}]}

If the server processing the transmission naively trusts the specified size, then an attacker can intentionally understate the size of the array, possibly resulting in a buffer overflow if the server attempts to read the entire data set into the memory it allocated for a smaller array.\n\n**Prerequisites.** - The targeted SOAP server must trust that the array size as stated in messages it receives is correct, but read through the entire content of the message regardless of the stated size of the array.\n\n**Resources required.** The attacker must be able to craft malformed SOAP messages, specifically, messages with arrays where the stated array size understates the actual size of the array in the message.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application to perform the buffer overflow on. In this attack, adversaries look for applications that utilize SOAP as a communication mechanism.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] Using the injection vector, the adversary sends the crafted SOAP message to the program, overflowing the buffer.\n\n**Mitigations.** - If the server either verifies the correctness of the stated array size or if the server stops processing an array once the stated number of elements have been read, regardless of the actual array size, then this attack will fail.

Data copied to the clipboard can be accessed by other applications, such as malware built to exfiltrate or log clipboard contents on a periodic basis. In this way, the adversary aims to garner information to which they are unauthorized.\n\n**Prerequisites.** - The adversary must have a means (i.e., a pre-installed tool or background process) by which to collect data from the clipboard and store it. That is, when the target copies data to the clipboard (e.g., to paste into another application), the adversary needs some means of capturing that data in a third location.\n\n**Skills required.** - To deploy a hidden process or malware on the system to automatically collect clipboard data.\n\n**Execution flow.** . ****: [Find an application that allows copying sensititve data to clipboad] An adversary first needs to find an application that allows copying and pasting of sensitive information.

Conducting this type of attack entails the adversary infecting the target with firmware altering malware, using known tools, and a payload. Once this malware is executed, the MBR is modified to include instructions to execute the payload at desired intervals and when the system is booted up. A successful attack will obtain persistence within the victim system even if the operating system is reinstalled and/or if the component is formatted or has its data erased.\n\n**Prerequisites.** - Advanced knowledge about the target component's firmware\n- Advanced knowledge about Master Boot Records (MBR)\n- Advanced knowledge about tools used to insert firmware altering malware.\n- Advanced knowledge about component shipments to the target organization.\n\n**Skills required.** - Ability to access and reverse engineer hardware component firmware.\n- Ability to intercept components in transit.\n- Ability to create malicious payload to be executed from MBR.\n- Ability to leverage known malware tools to infect target system and insert firmware altering malware/payload\n\n**Resources required.** Manufacturer source code for hardware components.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n**Prerequisites.** - The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Skills required.** - An attacker can try special characters in the URL and bypass the URL validation.\n- The attacker may write a script to defeat the input filtering mechanism.\n\n**Execution flow.** . ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL. The attacker find out that some characters are not filtered properly.\n. ****: The attacker crafts a malicious URL string request and sends it to the server.\n. ****: The server decodes and interprets the URL string. Unfortunately since the input filtering is not done properly, the special characters have harmful consequences.\n\n**Mitigations.** - Assume all input is malicious. Create an allowlist that defines all valid input to the software system based on the requirements specifications. Input that does not match against the allowlist should not be permitted to enter into the system.

The adversary could use running code in the context of another process to try to access process's memory, system/network resources, etc. The goal of this attack is to evade detection defenses and escalate privileges by masking the malicious code under an existing legitimate process. Examples of approaches include but not limited to: dynamic-link library (DLL) injection, portable executable injection, thread execution hijacking, ptrace system calls, VDSO hijacking, function hooking, reflective code loading, and more.\n\n**Prerequisites.** - The targeted application fails to verify the integrity of the running process that allows an adversary to execute arbitrary code.\n\n**Skills required.** - Knowledge of how to load malicious code into the memory space of a running process, as well as the ability to have the running process execute this code. For example, with DLL injection, the adversary must know how to load a DLL into the memory space of another running process, and cause this process to execute the code inside of the DLL.\n\n**Execution flow.** . ****: [Determine target process] The adversary determines a process with sufficient privileges that they wish to include code into.\n. ****: [Attempt to include simple code with known output] The adversary attempts to include very simple code into the existing process to determine if the code inclusion worked. The code will differ based on the approach used to include code into an existing process.\n. ****: [Include arbitrary code into existing process] Once an adversary has determined that including code into the existing process is possible, they will include code for a targeted purpose, such as accessing that process's memory.\n\n**Mitigations.** - Prevent unknown or malicious software from loading through using an allowlist policy.\n- Properly restrict the location of the software being used.\n- Leverage security kernel modules providing advanced access control and process restrictions like SELinux.

The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.\n\n**Prerequisites.** - This pattern of attack requires a temporal aspect to the servicing of a given request. Success can be achieved if the adversary can make requests that collectively take more time to complete than legitimate user requests within the same time frame.\n\n**Resources required.** To successfully execute this pattern of attack, a script or program is often required that is capable of continually engaging the target and maintaining sustained usage of a specific resource. Depending on the configuration of the target, it may or may not be necessary to involve a network or cluster of objects all capable of making parallel requests.\n\n**Mitigations.** - Potential mitigations include requiring a unique login for each resource request, constraining local unprivileged access by disallowing simultaneous engagements of the resource, or limiting access to the resource to one access per IP address. In such scenarios, the adversary would have to increase engagements either by launching multiple sessions manually or programmatically to counter such defenses.\n\n**Underlying weaknesses.** - CWE-400 (Uncontrolled Resource Consumption)\n\n**ATT&CK mapping.** - 1499 (Endpoint Denial of Service)\n\n## Reference: CAPEC-228 DTD Injection\n**CAPEC-228 DTD Injection (full record).** Abstraction: Detailed; Status: Draft; Severity: Medium; Likelihood: n/a\nAn attacker injects malicious content into an application's DTD in an attempt to produce a negative technical impact. DTDs are used to describe how XML documents are processed. Certain malformed DTDs (for example, those with excessive entity expansion as described in CAPEC 197) can cause the XML parsers that process the DTDs to consume excessive resources resulting in resource depletion.\n\n**Prerequisites.** - The target must be running an XML based application that leverages DTDs.\n\n**Execution flow.** . ****: [Survey the target] Using a browser or an automated tool, an attacker records all instances of web services to process XML requests.\n. ****: [Determine use of XML with DTDs] Examine application input to identify XML input that leverage the use of one or more DTDs.\n. ****: [Craft and inject XML containg malicious DTD payload]\n\n**Mitigations.** - Design: Sanitize incoming DTDs to prevent excessive expansion or other actions that could result in impacts like resource depletion.\n- Implementation: Disallow the inclusion of DTDs as part of incoming messages.\n- Implementation: Use XML parsing tools that protect against DTD attacks.\n\n**Related patterns.** - ChildOf: CAPEC-250\n- CanPrecede: CAPEC-197\n- CanPrecede: CAPEC-491\n\n**Underlying weaknesses.** - CWE-829 (Inclusion of Functionality from Untrusted Control Sphere)\n\n## Reference: CAPEC-229 Serialized Data Parameter Blowup\n**CAPEC-229 Serialized Data Parameter Blowup (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nThis attack exploits certain serialized data parsers (e.g., XML, YAML, etc.) which manage data in an inefficient manner. The attacker crafts an serialized data file with multiple configuration parameters in the same dataset. In a vulnerable parser, this results in a denial of service condition where CPU resources are exhausted because of the parsing algorithm. The weakness being exploited is tied to parser implementation and not language specific.\n\n**Prerequisites.** - The server accepts input in the form of serialized data and is using a parser with a runtime longer than O(n) for the insertion of a new configuration parameter in the data container.(examples are.NET framework 1.0 and 1.1)\n\n**Execution flow.** . ****: [Survey the target] Using a browser or an automated tool, an attacker records all instances of web services to process requests using serialized data.\n. ****: [Launch a Blowup attack] The attacker crafts malicious messages that contain multiple configuration parameters in the same dataset.\n\n**Mitigations.** - This attack may be mitigated completely by using a parser that is not using a vulnerable container.\n- Mitigation may limit the number of configuration parameters per dataset.\n\n**Example instances.** - In this example, assume that the victim is running a vulnerable parser such as.NET framework 1.0. This results in a quadratic runtime of O(n^2).\n- A document with n attributes results in (n^2)/2 operations to be performed. If an operation takes 100 nanoseconds then a document with 100,000 operations would take 500s to process. In this fashion a small message of less than 1MB causes a denial of service condition on the CPU resources.\n- A YAML bomb leverages references within a YAML file to create exponential growth in memory requirements. By creating a chain of keys whose values are a list of multiple references to the next key in the chain, the amount of memory and processing required to handle the data grows exponentially. This may lead to denial of service or instability resulting from excessive resource consumption.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n**Prerequisites.** - The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Skills required.** - An attacker can try special characters in the URL and bypass the URL validation.\n- The attacker may write a script to defeat the input filtering mechanism.\n\n**Execution flow.** . ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL.

Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An adversary can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the adversary can write to the program stack.\n\n**Prerequisites.** - The target application must accept a strings as user input, fail to sanitize string formatting characters in the user input, and process this string using functions that interpret string formatting characters.\n\n**Skills required.** - In order to discover format string vulnerabilities it takes only low skill, however, converting this discovery into a working exploit requires advanced knowledge on the part of the adversary.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Survey application] The adversary takes an inventory of the entry points of the application.\n. ****: [Determine user-controllable input susceptible to format string injection] Determine the user-controllable input susceptible to format string injection.

Some applications use user input to create LDAP queries that are processed by an LDAP server. For example, a user might provide their username during authentication and the username might be inserted in an LDAP query during the authentication process. An attacker could use this input to inject additional commands into an LDAP query that could disclose sensitive information. For example, entering a * in the aforementioned query might return information about all users on the system. This attack is very similar to an SQL injection attack in that it manipulates a query to gather additional information or coerce a particular return value.\n\n**Prerequisites.** - The target application must accept a string as user input, fail to sanitize characters that have a special meaning in LDAP queries in the user input, and insert the user-supplied string in an LDAP query which is then processed.\n\n**Skills required.** - The attacker needs to have knowledge of LDAP, especially its query syntax.\n\n**Execution flow.** . ****: [Survey application] The attacker takes an inventory of the entry points of the application.\n. ****: [Determine user-controllable input susceptible to LDAP injection] For each user-controllable input that the attacker suspects is vulnerable to LDAP injection, attempt to inject characters that have special meaning in LDAP (such as a single quote character, etc.).

Some parameter encodings use text characters as separators. For example, parameters in a HTTP GET message are encoded as name-value pairs separated by an ampersand (&). If an attacker can supply text strings that are used to fill in these parameters, then they can inject special characters used in the encoding scheme to add or modify parameters. For example, if user input is fed directly into an HTTP GET request and the user provides the value \"myInput&new_param=myValue\", then the input parameter is set to myInput, but a new parameter (new_param) is also added with a value of myValue. This can significantly change the meaning of the query that is processed by the server. Any encoding scheme where parameters are identified and separated by text characters is potentially vulnerable to this attack - the HTTP GET encoding used above is just one example.\n\n**Prerequisites.** - The target application must use a parameter encoding where separators and parameter identifiers are expressed in regular text.\n- The target application must accept a string as user input, fail to sanitize characters that have a special meaning in the parameter encoding, and insert the user-supplied string in an encoding which is then processed.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

For example, in the Java programming language the reflection libraries permit an application to inspect, load, and invoke classes and their components by name. If an adversary can control the input into these methods including the name of the class/method/field or the parameters passed to methods, they can cause the targeted application to invoke incorrect methods, read random fields, or even to load and utilize malicious classes that the adversary created. This can lead to the application revealing sensitive information, returning incorrect results, or even having the adversary take control of the targeted application.\n\n**Prerequisites.** - The target application must utilize reflection libraries and allow users to directly control the parameters to these methods. If the adversary can host classes where the target can invoke them, more powerful variants of this attack are possible.\n- The target application must accept a string as user input, fail to sanitize characters that have a special meaning in the parameter encoding, and insert the user-supplied string in an encoding which is then processed.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Related patterns.** - ChildOf: CAPEC-137\n\n**Underlying weaknesses.** - CWE-470 (Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection'))\n\n## Reference: CAPEC-139 Relative Path Traversal\n**CAPEC-139 Relative Path Traversal (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nAn attacker exploits a weakness in input validation on the target by supplying a specially constructed path utilizing dot and slash characters for the purpose of obtaining access to arbitrary files or resources.

Lock Bumping is the use of a special type of key that can be tapped or bumped to cause the pins within the lock to fall into temporary alignment, allowing the lock to be opened. Lock bumping allows an attacker to open a lock without having the correct key. A standard lock is secured by a set of internal pins that prevent the device from turning.

Lock picking attacks have the advantage of being non-invasive in that if performed correctly the lock will not be damaged. A standard lock pin-and-tumbler lock is secured by a set of internal pins that prevent the tumbler device from turning. Spring loaded driver pins push down on the key pins preventing rotation so that the bolt remains in a locked position.. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate.

A Pick Gun is a special type of lock picking instrument that works on similar principles as lock bumping. A snap gun is a hand-held device with an attached metal pick. The metal pick strikes the pins within the lock, transferring motion from the key pins to the driver pins and forcing the lock into momentary alignment. A standard lock is secured by a set of internal pins that prevent the device from turning. Spring loaded driver pins push down on the key pins. When the correct key is inserted, the ridges on the key push the key pins up and against the driver pins, causing correct alignment which allows the lock cylinder to rotate. A Snap Gun exploits this design by using a metal pin to strike all of the key pins at once, forcing the driver pins to shift into an unlocked position.

Most attacks against electronic access controls follow similar methods but utilize different tools. Some electronic locks utilize magnetic strip cards, others employ RFID tags embedded within a card or badge, or may involve more sophisticated protections such as voice-print, thumb-print, or retinal biometrics. Magnetic Strip and RFID technologies are the most widespread because they are cost effective to deploy and more easily integrated with other electronic security measures.

Magstripe cards encode data on a band of iron-based magnetic particles arrayed in a stripe along a rectangular card. Most magstripe card data formats conform to ISO standards 7810, 7811, 7813, 8583, and 4909. The primary advantage of magstripe technology is ease of encoding and portability, but this also renders magnetic strip cards susceptible to unauthorized duplication. If magstripe cards are used for access control, all an attacker need do is obtain a valid card long enough to make a copy of the card and then return the card to its location (i.e. a co-worker's desk). Magstripe reader/writers are widely available as well as software for analyzing data encoded on the cards.

Networked applications may expect network location information in a specific format, such as fully qualified domains names (FQDNs), URL, IP address, or IP Address ranges. If the location information is not validated against a variety of different possible encodings and formats, the adversary can use an alternate format to bypass application access control.\n\n**Prerequisites.** - The target software must fail to anticipate all of the possible valid encodings of an IP/web address.\n- The adversary must have the ability to communicate with the server.\n\n**Skills required.** - The adversary has only to try IP address format combinations.\n\n**Resources required.** The adversary needs to have knowledge of an alternative IP address encoding that bypasses the access control policy of an application.

This attack differs from other forms of API abuse in that the attacker is indiscriminately attempting to invoke options in the hope that one of them will work rather than specifically targeting a known option.

An attacker could use this input to inject additional commands into an LDAP query that could disclose sensitive information.

A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.

The malicious application is designed to target a specific web application and is used to load the target web pages via the WebView component. For example, an adversary may develop an application that interacts with Facebook via WebView and adds a new feature that a user desires. The user would install this 3rd party app instead of the Facebook app.\n\n**Execution flow.** . ****: [Determine target web application] An adversary first needs to determine what web application they wish to target.\n. ****: [Create malicious application] An adversary creates an application, often mobile, that incorporates a WebView component to display the targeted web application.

The user is enticed to provide information or visit a compromised web site via this message. Apart from the manner in which the attack is initiated, the attack proceeds as a standard Phishing attack.\n\n**Prerequisites.** - An adversary needs mobile phone numbers to initiate contact with the victim.\n- An adversary needs to correctly guess the entity with which the victim does business and impersonate it. Most of the time phishers just use the most popular banks/services and send out their \"hooks\" to many potential victims.\n- An adversary needs to have a sufficiently compelling call to action to prompt the user to take action.\n- The replicated website needs to look extremely similar to the original website and the URL used to get to that website needs to look like the real URL of the said business entity.\n\n**Skills required.** - Basic knowledge about websites: obtaining them, designing and implementing them, etc.\n\n**Resources required.** Either mobile phone or access to a web resource that allows text messages to be sent to mobile phones. Resources needed for regular Phishing attack.\n\n**Execution flow.** . ****: [Obtain domain name and certificate to spoof legitimate site] This optional step can be used to help the adversary impersonate the legitimate site more convincingly. The adversary can use homograph or similar attacks to convince users that they are using the legitimate website. Note that this step is not required for phishing attacks, and many phishing attacks simply supply URLs containing an IP address and no SSL certificate.\n. ****: [Explore legitimate website and create duplicate] An adversary creates a website (optionally at a URL that looks similar to the original URL) that closely resembles the website that they are trying to impersonate. That website will typically have a login form for the victim to put in their authentication credentials.

Attackers use this class of attacks to cause applications to enter unstable states, overwrite or expose sensitive information, and even execute arbitrary code with the application's privileges. This class of attacks differs from attacks on configuration information (even if file-based) in that file manipulation causes the file processing to result in non-standard behaviors, such as buffer overflows or use of the incorrect interpreter. Configuration attacks rely on the application interpreting files correctly in order to insert harmful configuration information. Likewise, resource location attacks rely on controlling an application's ability to locate files, whereas File Manipulation attacks do not require the application to look in a non-default location, although the two classes of attacks are often combined.\n\n**Prerequisites.** - The target must use the affected file without verifying its integrity.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

ADS allows multiple \"files\" to be stored in one directory entry referenced as filename:streamname. One or more alternate data streams may be stored in any file or directory. Normal Microsoft utilities do not show the presence of an ADS stream attached to a file. The additional space for the ADS is not recorded in the displayed file size. The additional space for ADS is accounted for in the used space on the volume. An ADS can be any type of file. ADS are copied by standard Microsoft utilities between NTFS volumes. ADS can be used by an attacker or intruder to hide tools, scripts, and data from detection by normal system utilities. Many anti-virus programs do not check for or scan ADS. Windows Vista does have a switch (-R) on the command line DIR command that will display alternate streams.\n\n**Prerequisites.** - The target must be running the Microsoft NTFS file system.\n\n**Resources required.** The attacker must have command line or programmatic access to the target's files system with write/read permissions.\n\n**Mitigations.** - Design: Use FAT file systems which do not support Alternate Data Streams.\n- Implementation: Use Vista dir with the -R switch or utility to find Alternate Data Streams and take appropriate action with those discovered.\n- Implementation: Use products that are Alternate Data Stream aware for virus scanning and system security operations.\n\n**Related patterns.** - ChildOf: CAPEC-636\n\n**Underlying weaknesses.** - CWE-212 (Improper Removal of Sensitive Information Before Storage or Transfer)\n- CWE-69 (Improper Handling of Windows ::DATA Alternate Data Stream)\n\n## Reference: CAPEC-169 Footprinting\n**CAPEC-169 Footprinting (full record).** Abstraction: Meta; Status: Stable; Severity: Very Low; Likelihood: High\nAn adversary engages in probing and exploration activities to identify constituents and properties of the target.\n\n**Prerequisites.** - An application must publicize identifiable information about the system or application through voluntary or involuntary means. Certain identification details of information systems are visible on communication networks (e.g., if an adversary uses a sniffer to inspect the traffic) due to their inherent structure and protocol standards. Any system or network that can be detected can be footprinted. However, some configuration choices may limit the useful information that can be collected during a footprinting attack.\n\n**Skills required.** - The adversary knows how to send HTTP request, run the scan tool.\n\n**Resources required.** The adversary requires a variety of tools to collect information about the target. These include port/network scanners and tools to analyze responses from applications to determine version and configuration information.

Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.\n\n**Prerequisites.** - An attacker and the victim are both using the same WiFi network.\n- The victim has an active session with a target system.\n- The victim is not using a secure channel to communicate with the target system (e.g. SSL, VPN, etc.)\n- The victim initiated communication with a target system that requires transfer of the session token or the target application uses AJAX and thereby periodically \"rings home\" asynchronously using the session token\n\n**Skills required.** - Easy to use tools exist to automate this attack.\n\n**Resources required.** A packet sniffing tool, such as wireshark, can be used to capture session information.\n\n**Execution flow.** . ****: [Detect Unprotected Session Token Transfer] The attacker sniffs on the wireless network to detect unencrypted traffic that contains session tokens.\n. ****: [Capture session token] The attacker uses sniffing tools to capture a session token from traffic.\n. ****: [Insert captured session token] The attacker attempts to insert a captured session token into communication with the targeted application to confirm viability for exploitation.\n. ****: [Session Token Exploitation] The attacker leverages the captured session token to interact with the targeted application in a malicious fashion, impersonating the victim.\n\n**Mitigations.** - Make sure that HTTPS is used to communicate with the target system.

This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.\n\n**Prerequisites.** - In order to feasibly execute this type of attack, some valuable data must be present in client software.\n- Additionally, this information must be unprotected, or protected in a flawed fashion, or through a mechanism that fails to resist reverse engineering, statistical, or other attack.\n\n**Skills required.** - The attacker must possess knowledge of client code structure as well as ability to reverse-engineer or decompile it or probe it in other ways. This knowledge is specific to the technology and language used for the client distribution\n\n**Resources required.** The attacker must possess access to the system or code being exploited. Such access, for this set of attacks, will likely be physical. The attacker will make use of reverse engineering technologies, perhaps for data or to extract functionality from the binary. Such tool use may be as simple as \"Strings\" or a hex editor. Removing functionality may require the use of only a hex editor, or may require aspects of the toolchain used to construct the application: for instance the Adobe Flash development environment.

The adversary can either modify the search path a program uses, like a PATH variable or classpath, or they can manipulate resources on the path to point to their malicious components. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker.\n\n**Prerequisites.** - The attacker must be able to write to redirect search paths on the victim host.\n\n**Skills required.** - To identify and execute against an over-privileged system interface\n\n**Mitigations.** - Design: Enforce principle of least privilege\n- Design: Ensure that the program's compound parts, including all system dependencies, classpath, path, and so on, are secured to the same or higher level assurance as the program\n- Implementation: Host integrity monitoring\n\n**Consequences.** - None (None)\n- None (None)\n\n**Example instances.** - Another method is to redirect commands by aliasing one legitimate command to another to create unexpected results. the Unix command \"rm\" could be aliased to \"mv\" and move all files the victim thinks they are deleting to a directory the attacker controls. In a Unix shell.profile setting\n- In this case the attacker retains a copy of all the files the victim attempts to remove.\n- A standard UNIX path looks similar to this\n- If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf:\n- This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts.

The techniques require use of specialized software that allow the attacker to perform adversary-in-the-middle (CAPEC-94) communications between the web browser and the remote system. Despite the use of AiTH software, the attack is actually directed at the server, as the client is one node in a series of content brokers that pass information along to the application framework.

Performing this attack allows the attacker to manipulate content in such a way as to produce messages or content that look authentic but may contain deceptive links, substitute one item or another, spoof an existing item and conduct a false exchange, or otherwise change the amounts or identity of what is being exchanged. The techniques require use of specialized software that allow the attacker to man-in-the-middle communications between the web browser and the remote system in order to change the content of various application elements. Often, items exchanged in game can be monetized via sales for coin, virtual dollars, etc. The purpose of the attack is for the attack to scam the victim by trapping the data packets involved the exchange and altering the integrity of the transfer process.\n\n**Prerequisites.** - Targeted software is utilizing application framework APIs\n\n**Resources required.** A software program that allows the use of adversary-in-the-middle communications (CAPEC-94) between the client and server, such as a man-in-the-middle proxy.\n\n**Related patterns.** - ChildOf: CAPEC-384\n\n**Underlying weaknesses.** - CWE-471 (Modification of Assumed-Immutable Data (MAID))\n- CWE-345 (Insufficient Verification of Data Authenticity)\n- CWE-346 (Origin Validation Error)\n- CWE-602 (Client-Side Enforcement of Server-Side Security)\n- CWE-311 (Missing Encryption of Sensitive Data)"}]}

ATA Security is often employed to protect hard disk information from unauthorized access. The mechanism requires the user to type in a password before the BIOS is allowed access to drive contents. Some implementations of ATA security will accept the ATA command to update the password without the user having authenticated with the BIOS. This occurs because the security mechanism assumes the user has first authenticated via the BIOS prior to sending commands to the drive. Various methods exist for exploiting this flaw, the most common being installing the ATA protected drive into a system lacking ATA security features (a.k.a. hot swapping). Once the drive is installed into the new system the BIOS can be used to reset the drive password.\n\n**Prerequisites.** - Access to the system containing the ATA Drive so that the drive can be physically removed from the system.\n\n**Mitigations.** - Avoid using ATA password security when possible.\n- Use full disk encryption to protect the entire contents of the drive or sensitive partitions on the drive.\n- Leverage third-party utilities that interface with self-encrypting drives (SEDs) to provide authentication, while relying on the SED itself for data encryption.\n\n**Example instances.** - The A-FF Repair Station tool is a data recovery utility that can be used for ATA password removal (both High and Maximum level) and firmware area recovery. An adversary with access to this tool could reset the ATA password to bypass this security feature and unlock the hard drive. The adversary could then obtain any data contained within the drive. [REF-702]\n- An adversary gains physical access to the targeted hard drive and installs it into a system that does not support ATA security features. Once the drive is installed in the feature-lacking system, the adversary is able to reset the hard drive password via the BIOS.

The attacker could manipulate the system if the attacker-created file is trusted by the operating system or an application component that attempts to load the original file. Applications often load or include external files, such as libraries or configuration files. These files should be protected against malicious manipulation. However, if the application only uses the name of the file when locating it, an attacker may be able to create a file with the same name and place it in a directory that the application will search before the directory with the legitimate file is searched. Because the attackers' file is discovered first, it would be used by the target application.

This attack pattern occurs where an attacker can provide a crafted link to a Flash document (SWF file) which, when followed, will cause additional malicious instructions to be executed. The attacker does not need to serve or control the Flash document. The attack takes advantage of the fact that Flash files can reference external URLs.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n**Prerequisites.** - The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Skills required.** - An attacker can try special characters in the URL and bypass the URL validation.\n- The attacker may write a script to defeat the input filtering mechanism.\n\n**Execution flow.** . ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL.

This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.\n\n**Prerequisites.** - HTTP protocol is usedWeb server used is vulnerable to denial of service via HTTP flooding\n\n**Resources required.** Ability to issues hundreds of HTTP requests\n\n**Mitigations.** - Configuration: Configure web server software to limit the waiting period on opened HTTP sessions\n- Design: Use load balancing mechanisms\n\n**Related patterns.** - ChildOf: CAPEC-227\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n- CWE-772 (Missing Release of Resource after Effective Lifetime)\n\n**ATT&CK mapping.** - 1499.002 (Endpoint Denial of Service: Service Exhaustion Flood)\n\n## Reference: CAPEC-47 Buffer Overflow via Parameter Expansion\n**CAPEC-47 Buffer Overflow via Parameter Expansion (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: Medium\nIn this attack, the target software is given input that the adversary knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.\n\n**Prerequisites.** - The program expands one of the parameters passed to a function with input controlled by the user, but a later function making use of the expanded parameter erroneously considers the original, not the expanded size of the parameter.\n- The expanded parameter is used in the context where buffer overflow may become possible due to the incorrect understanding of the parameter size (i.e. thinking that it is smaller than it really is).\n\n**Skills required.** - Finding this particular buffer overflow may not be trivial. Also, stack and especially heap based buffer overflows require a lot of knowledge if the intended goal is arbitrary code execution. Not only that the adversary needs to write the shell code to accomplish their goals, but the adversary also needs to find a way to get the program execution to jump to the planted shell code. There also needs to be sufficient room for the payload. So not every buffer overflow will be exploitable, even by a skilled adversary.\n\n**Resources required.** Access to the program source or binary. If the program is only available in binary then a disassembler and other reverse engineering tools will be helpful.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. Adversaries often look for applications that accept user input and that perform manual memory management.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the input to be given to the program.

Traditionally SQL injections attacks are viewed as a way to gain unauthorized read access to the data stored in the database, modify the data in the database, delete the data, etc. However, almost every data base management system (DBMS) system includes facilities that if compromised allow an attacker complete access to the file system, operating system, and full access to the host running the database. The attacker can then use this privileged access to launch subsequent attacks. These facilities include dropping into a command shell, creating user defined functions that can call system level libraries present on the host machine, stored procedures, etc.\n\n**Prerequisites.** - A vulnerable DBMS is usedA SQL injection exists that gives an attacker access to the database or an attacker has access to the DBMS via other means\n\n**Skills required.** - Low level knowledge of the various facilities available in different DBMS systems for interacting with the file system and operating system\n\n**Execution flow.** . ****: The adversary identifies a database management system running on a machine they would like to gain control over, or on a network they want to move laterally through.\n. ****: The adversary goes about the typical steps of an SQL injection and determines if an injection is possible.\n. ****: Once the Adversary determines that an SQL injection is possible, they must ensure that the requirements for the attack are met. These are a high privileged session user and batched query support. This is done in similar ways to discovering if an SQL injection is possible.\n. ****: If the requirements are met, based on the database management system that is running, the adversary will find or create user defined functions (UDFs) that can be loaded as DLLs.

Email software has become increasingly sophisticated and feature-rich. In addition, email applications are ubiquitous and connected directly to the Web making them ideal targets to launch and propagate attacks. As the user demand for new functionality in email applications grows, they become more like browsers with complex rendering and plug in routines. As more email functionality is included and abstracted from the user, this creates opportunities for attackers. Virtually all email applications do not list email header information by default, however the email header contains valuable attacker vectors for the attacker to exploit particularly if the behavior of the email client application is known. Meta-characters are hidden from the user, but can contain scripts, enumerations, probes, and other attacks against the user's system.\n\n## Reference: CAPEC-298 UDP Ping\n**CAPEC-298 UDP Ping (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary sends a UDP datagram to the remote host to determine if the host is alive. If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target. The goal is to solicit an 'ICMP port unreachable' message from the target, indicating that the host is alive. UDP pings are useful because some firewalls are not configured to block UDP datagrams sent to strange or typically unused ports, like ports in the 65K range. Additionally, while some firewalls may filter incoming ICMP, weaknesses in firewall rule-sets may allow certain types of ICMP (host unreachable, port unreachable) which are useful for UDP ping attempts.\n\n**Prerequisites.** - The adversary requires the ability to send a UDP datagram to a remote host and receive a response.\n- The adversary requires the ability to craft custom UDP Packets for use during network reconnaissance.\n- The target's firewall must not be configured to block egress ICMP messages.\n\n**Resources required.** UDP pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language. Packet injection tools are also useful for this purpose. Depending upon the technique used it may also be necessary to sniff the network in order to see the response.\n\n**Mitigations.** - Configure your firewall to block egress ICMP messages.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Related patterns.** - ChildOf: CAPEC-292\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n\n## Reference: CAPEC-299 TCP SYN Ping\n**CAPEC-299 TCP SYN Ping (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary uses TCP SYN packets as a means towards host discovery. Typical RFC 793 behavior specifies that when a TCP port is open, a host must respond to an incoming SYN \"synchronize\" packet by completing stage two of the 'three-way handshake' - by sending an SYN/ACK in response. When a port is closed, RFC 793 behavior is to respond with a RST \"reset\" packet. This behavior can be used to 'ping' a target to see if it is alive by sending a TCP SYN packet to a port and then looking for a RST or an ACK packet in response.\n\n**Prerequisites.** - The ability to send a TCP SYN packet to a remote target. Depending upon the operating system, the ability to craft SYN packets may require elevated privileges.\n\n**Skills required.** - The adversary needs to know how to craft and send protocol commands from the command line or within a tool.\n\n**Resources required.** SYN pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language.

An adversary can intentionally introduce leading \"ghost\" characters (extra characters that don't affect the validity of the request at the API layer) that enable the input to pass the filters and therefore process the adversary's input. This occurs when the targeted API will accept input data in several syntactic forms and interpret it in the equivalent semantic way, while the filter does not take into account the full spectrum of the syntactic forms acceptable to the targeted API.\n\n**Prerequisites.** - The targeted API must ignore the leading ghost characters that are used to get past the filters for the semantics to be the same.\n\n**Skills required.** - The ability to make an API request, and knowledge of \"ghost\" characters that will not be filtered by any input validation. These \"ghost\" characters must be known to not affect the way in which the request will be interpreted.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser, an automated tool or by inspecting the application, an adversary records all entry points to the application.\n. ****: [Probe entry points to locate vulnerabilities] The adversary uses the entry points gathered in the \"Explore\" phase as a target list and injects various leading 'Ghost' character sequences to determine how to application filters them.\n. ****: [Bypass input filtering] Using what the adversary learned about how the application filters input data, they craft specific input data that bypasses the filter. This can lead to directory traversal attacks, arbitrary shell command execution, corruption of files, etc.\n\n**Mitigations.** - Use an allowlist rather than a denylist input validation.\n- Canonicalize all data prior to validation.\n- Take an iterative approach to input validation (defense in depth).

By using a privleged thread to do their bidding, adversaries can evade process-based detection that would stop an attack that creates a new process. This can lead to an adversary gaining access to the process's memory and can also enable elevated privileges. The most common way to perform this attack is by suspending an existing thread and manipulating its memory.\n\n**Prerequisites.** - The application in question employs a threaded model of execution with the threads operating at, or having the ability to switch to, a higher privilege level than normal users\n- In order to feasibly execute this class of attacks, the adversary must have the ability to hijack a privileged thread. This ability includes, but is not limited to, modifying environment variables that affect the process the thread belongs to, or calling native OS calls that can suspend and alter process memory. This does not preclude network-based attacks, but makes them conceptually more difficult to identify and execute.\n\n**Skills required.** - Hijacking a thread involves knowledge of how processes and threads function on the target platform, the design of the target application as well as the ability to identify the primitives to be used or manipulated to hijack the thread.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. The adversary needs to be able to latch onto a privileged thread. The adversary does, however, need to be able to program, compile, and link to the victim binaries being executed so that it will turn control of a privileged thread over to the adversary's malicious code. This is the case even if the adversary conducts the attack remotely.\n\n**Execution flow.** . ****: [Determine target thread] The adversary determines the underlying system thread that is subject to user-control\n. ****: [Gain handle to thread] The adversary then gains a handle to a process thread.\n.

By sending a very large SOAP array declaration to the web service, the attacker forces the web service to allocate space for the array elements before they are parsed by the XML parser. The attacker message is typically small in size containing a large array declaration of say 1,000,000 elements and a couple of array elements. This attack targets exhaustion of the memory resources of the web service.\n\n**Prerequisites.** - This type of an attack requires the attacker to know the endpoint of the web service, and be able to reach the endpoint with a malicious SOAP message.\n\n**Mitigations.** - Enforce strict schema validation. The schema should enforce a maximum number of array elements. If the number of maximum array elements can't be limited another validation method should be used. One such method could be comparing the declared number of items in the array with the existing number of elements of the array.

The essential part of the guidance is creating the following rule \"IF FO=1 and PROTOCOL=TCP then DROP PACKET\" as this mitigated both tiny fragment and overlapping fragment attacks in IPv4. In IPv6 overlapping(RFC5722) additional steps may be required such as deep packet inspection. The delayed fragments may be mitigated by enforcing a timeout on the transmission to receive all packets by a certain time since the first packet is received. According to RFC2460 IPv6 implementations should enforce a rule to discard all fragments if the fragments are not ALL received within 60 seconds of the FIRST arriving fragment.\n\n**Related patterns.** - ChildOf: CAPEC-130\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n- CWE-404 (Improper Resource Shutdown or Release)\n\n## Reference: CAPEC-495 UDP Fragmentation\n**CAPEC-495 UDP Fragmentation (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker may execute a UDP Fragmentation attack against a target server in an attempt to consume resources such as bandwidth and CPU. IP fragmentation occurs when an IP datagram is larger than the MTU of the route the datagram has to traverse. Typically the attacker will use large UDP packets over 1500 bytes of data which forces fragmentation as ethernet MTU is 1500 bytes. This attack is a variation on a typical UDP flood but it enables more network bandwidth to be consumed with fewer packets. Additionally it has the potential to consume server CPU resources and fill memory buffers associated with the processing and reassembling of fragmented packets.\n\n**Prerequisites.** - This type of an attack requires the attacker to be able to generate fragmented IP traffic containing crafted data.\n\n**Mitigations.** - This attack may be mitigated by changing default cache sizes to be larger at the OS level. Additionally rules can be enforced to prune the cache with shorter timeouts for packet reassembly as the cache nears capacity.\n\n**Related patterns.** - ChildOf: CAPEC-130\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n- CWE-404 (Improper Resource Shutdown or Release)\n\n## Reference: CAPEC-496 ICMP Fragmentation\n**CAPEC-496 ICMP Fragmentation (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker may execute a ICMP Fragmentation attack against a target with the intention of consuming resources or causing a crash.

The attacker these sends these messages to a target host which causes the host to become non-responsive. Another vector may be sending a fragmented ICMP message to a target host with incorrect sizes in the header which causes the host to hang.\n\n**Prerequisites.** - This type of an attack requires the target system to be running a vulnerable implementation of IP, and the attacker needs to ability to send arbitrary sized ICMP packets to the target.\n\n**Mitigations.** - This attack may be mitigated through egress filtering based on ICMP payload so a network is a \"good neighbor\" to other networks.

This can be accomplished by setting the key window's hidden property to YES. This code to hide the contents should be placed in both the applicationWillResignActive and applicationDidEnterBackground methods.\n\n**Related patterns.** - ChildOf: CAPEC-545\n\n**Underlying weaknesses.** - CWE-359 (Exposure of Private Personal Information to an Unauthorized Actor)\n\n## Reference: CAPEC-499 Android Intent Intercept\n**CAPEC-499 Android Intent Intercept (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary, through a previously installed malicious application, intercepts messages from a trusted Android-based application in an attempt to achieve a variety of different objectives including denial of service, information disclosure, and data injection. An implicit intent sent from a trusted application can be received by any application that has declared an appropriate intent filter. If the intent is not protected by a permission that the malicious application lacks, then the attacker can gain access to the data contained within the intent. Further, the intent can be either blocked from reaching the intended destination, or modified and potentially forwarded along.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application is used to intercept implicit intents.\n\n**Execution flow.** . ****: [Find an android application that uses implicit intents] Since this attack only works on android applications that use implicit intents, rather than explicit intents, an adversary must first identify an app that uses implicit intents. They must also determine what the contents of the intents being sent are such that a malicious application can get sent these intents.\n. ****: [Create a malicious app] The adversary must create a malicious android app meant to intercept implicit intents from a target application\n. ****: [Get user to download malicious app] The adversary must get a user using the targeted app to download the malicious app by any means necessary\n. ****: [Intercept Implicit Intents] Once the malicious app is downloaded, the android device will forward any implicit intents from the target application to the malicious application, allowing the adversary to gaina access to the contents of the intent. The adversary can proceed with any attack using the contents of the intent.\n\n**Mitigations.** - To mitigate this type of an attack, explicit intents should be used whenever sensitive data is being sent. An explicit intent is delivered to a specific application as declared within the intent, whereas the Android operating system determines who receives an implicit intent which could potentially be a malicious application.

The attacker crafts an serialized data file with multiple configuration parameters in the same dataset. In a vulnerable parser, this results in a denial of service condition where CPU resources are exhausted because of the parsing algorithm. The weakness being exploited is tied to parser implementation and not language specific.\n\n**Prerequisites.** - The server accepts input in the form of serialized data and is using a parser with a runtime longer than O(n) for the insertion of a new configuration parameter in the data container.(examples are.NET framework 1.0 and 1.1)\n\n**Execution flow.** . ****: [Survey the target] Using a browser or an automated tool, an attacker records all instances of web services to process requests using serialized data.\n. ****: [Launch a Blowup attack] The attacker crafts malicious messages that contain multiple configuration parameters in the same dataset.\n\n**Mitigations.** - This attack may be mitigated completely by using a parser that is not using a vulnerable container.\n- Mitigation may limit the number of configuration parameters per dataset.\n\n**Example instances.** - In this example, assume that the victim is running a vulnerable parser such as.NET framework 1.0. This results in a quadratic runtime of O(n^2).\n- A document with n attributes results in (n^2)/2 operations to be performed. If an operation takes 100 nanoseconds then a document with 100,000 operations would take 500s to process. In this fashion a small message of less than 1MB causes a denial of service condition on the CPU resources.\n- A YAML bomb leverages references within a YAML file to create exponential growth in memory requirements. By creating a chain of keys whose values are a list of multiple references to the next key in the chain, the amount of memory and processing required to handle the data grows exponentially. This may lead to denial of service or instability resulting from excessive resource consumption.

It may be possible for an adversary to inject data that may have an adverse effect on the parser when it is being processed.

In certain instances, however, specific knowledge of the database employed may be required.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Survey application] The attacker first takes an inventory of the functionality exposed by the application.\n. ****: [Determine user-controllable input susceptible to injection] Determine the user-controllable input susceptible to injection. For each user-controllable input that the attacker suspects is vulnerable to SQL injection, attempt to inject characters that have special meaning in SQL (such as a single quote character, a double quote character, two hyphens, a parenthesis, etc.). The goal is to create a SQL query with an invalid syntax.\n. ****: [Experiment with SQL Injection vulnerabilities] After determining that a given input is vulnerable to SQL Injection, hypothesize what the underlying query looks like. Iteratively try to add logic to the query to extract information from the database, or to modify or delete information in the database.\n. ****: [Exploit SQL Injection vulnerability] After refining and adding various logic to SQL queries, craft and execute the underlying SQL query that will be used to attack the target system. The goal is to reveal, modify, and/or delete database data, using the knowledge obtained in the previous step. This could entail crafting and executing multiple SQL queries if a denial of service attack is the intent.

Mobile device users often Root/Jailbreak their devices in order to gain administrative control over the mobile operating system and/or to install third-party mobile applications that are not provided by authorized application stores (e.g. Google Play Store and Apple App Store). Adversaries may further leverage these capabilities to escalate privileges or bypass access control on legitimate applications. Although many mobile applications check if a mobile device is Rooted/Jailbroken prior to authorized use of the application, adversaries may be able to \"hook\" code in order to circumvent these checks. Successfully evading Root/Jailbreak detection allows an adversary to execute administrative commands, obtain confidential data, impersonate legitimate users of the application, and more.\n\n**Prerequisites.** - The targeted application must be non-restricted to allow code hooking.\n\n**Skills required.** - Knowledge about Root/Jailbreak detection and evasion techniques.\n- Knowledge about code hooking.\n\n**Resources required.** The adversary must have a Rooted/Jailbroken mobile device.

Mobile device users often Root/Jailbreak their devices in order to gain administrative control over the mobile operating system and/or to install third-party mobile applications that are not provided by authorized application stores (e.g. Google Play Store and Apple App Store). Rooting/Jailbreaking a mobile device also provides users with access to system debuggers and disassemblers, which can be leveraged to exploit applications by dumping the application's memory at runtime in order to remove or bypass signature verification methods. This further allows the adversary to evade Root/Jailbreak detection mechanisms, which can result in execution of administrative commands, obtaining confidential data, impersonating legitimate users of the application, and more.\n\n**Prerequisites.** - A debugger must be able to be inserted into the targeted application.\n\n**Skills required.** - Knowledge about Root/Jailbreak detection and evasion techniques.\n- Knowledge about runtime debugging.\n\n**Resources required.** The adversary must have a Rooted/Jailbroken mobile device with debugging capabilities.\n\n**Execution flow.** . ****: [Identify application with attack potential] The adversary searches for and identifies a mobile application that could be exploited for malicious purposes (e.g. banking, voting, or medical applications).\n. ****: [Debug the target application] The adversary inserts the debugger into the program entry point of the mobile application, after the application's signature has been identified, to dump its memory contents.\n. ****: [Remove application signature verification methods] Remove signature verification methods from the decrypted code and resign the application with a self-signed certificate.\n. ****: [Execute the application and evade Root/Jailbreak detection methods] The application executes with the self-signed certificate, while believing it contains a trusted certificate.

Through the injected code, an adversary is able to manipulate the DOM tree and cookies of the page, expose sensitive information, and can launch attacks against the web application from within the web page.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the device and convince the user to execute it. The malicious application is designed to target a specific web application and is used to load the target web pages via the WebView component. For example, an adversary may develop an application that interacts with Facebook via WebView and adds a new feature that a user desires. The user would install this 3rd party app instead of the Facebook app.\n\n**Execution flow.** . ****: [Determine target web application] An adversary first needs to determine what web application they wish to target.\n. ****: [Create malicious application] An adversary creates an application, often mobile, that incorporates a WebView component to display the targeted web application. This malicious application needs to downloaded by a user, so adversaries will make this application useful in some way.\n. ****: [Get the victim to download and run the application] An adversary needs to get the victim to willingly download and run the application.\n. ****: [Inject malicious code] Once the victim runs the malicious application and views the targeted web page in the WebView component, the malicious application will inject malicious JavaScript code into the web application. This is done by using WebView's loadURL API, which can inject arbitrary JavaScript code into pages loaded by the WebView component with the same privileges. This is often done by adding a script tag to the document body with a src destination to a remote location that serves malicious JavaScript code.\n\n**Mitigations.** - The only known mitigation to this type of attack is to keep the malicious application off the system.

The malicious activity is then used to mimic the trusted activity's user interface and prompt the target to enter sensitive data as if they were interacting with the trusted activity.\n\n**Prerequisites.** - The adversary must have previously installed the malicious application onto the Android device that will run in place of the trusted activity.\n\n**Skills required.** - The adversary must typically overcome network and host defenses in order to place malware on the system.\n\n**Resources required.** Malware capable of acting on the adversary's objectives.\n\n**Execution flow.** . ****: [Find an android application that uses implicit intents] Since this attack only works on android applications that use implicit intents, rather than explicit intents, an adversary must first identify an app that uses implicit intents to launch an Android-based trusted activity, and what that activity is.\n. ****: [Create a malicious app] The adversary must create a malicious android app meant to intercept implicit intents to launch an Adroid-based trusted activity. This malicious app will mimic the trusted activiy's user interface to get the user to enter sensitive data.\n. ****: [Get user to download malicious app] The adversary must get a user using the targeted app to download the malicious app by any means necessary\n. ****: [Gather sensitive data through malicious app] Once the target application sends an implicit intent to launch a trusted activity, the malicious app will be launched instead that looks identical to the interface of that activity. When the user enters sensitive information it will be captured by the malicious app.\n\n**Mitigations.** - To mitigate this type of an attack, explicit intents should be used whenever sensitive data is being sent.

Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application will be used to issue spoofed intents.\n\n**Mitigations.** - To limit one's exposure to this type of attack, developers should avoid exporting components unless the component is specifically designed to handle requests from untrusted applications. Developers should be aware that declaring an intent filter will automatically export the component, exposing it to public access. Critical, state-changing actions should not be placed in exported components. If a single component handles both interand intra-application requests, the developer should consider dividing that component into separate components. If a component must be exported (e.g., to receive system broadcasts), then the component should dynamically check the caller's identity prior to performing any operations. Requiring Signature or SignatureOrSystem permissions is an effective way of limiting a component's exposure to a set of trusted applications. Finally, the return values of exported components can also leak private data, so developers should check the caller's identity prior to returning sensitive values.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)\n\n## Reference: CAPEC-503 WebView Exposure\n**CAPEC-503 WebView Exposure (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API.

Once loaded, the malicious web page will have the same permissions as the target application and will have access to all registered interfaces. Both the permission and the interface must be in place for the functionality to be exposed.\n\n**Mitigations.** - To mitigate this type of an attack, an application should limit permissions to only those required and should verify the origin of all web content it loads.\n\n**Related patterns.** - ChildOf: CAPEC-122\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)"}]}

ATA Security is often employed to protect hard disk information from unauthorized access. The mechanism requires the user to type in a password before the BIOS is allowed access to drive contents. Some implementations of ATA security will accept the ATA command to update the password without the user having authenticated with the BIOS. This occurs because the security mechanism assumes the user has first authenticated via the BIOS prior to sending commands to the drive. Various methods exist for exploiting this flaw, the most common being installing the ATA protected drive into a system lacking ATA security features (a.k.a. hot swapping). Once the drive is installed into the new system the BIOS can be used to reset the drive password.\n\n**Prerequisites.** - Access to the system containing the ATA Drive so that the drive can be physically removed from the system.\n\n**Mitigations.** - Avoid using ATA password security when possible.\n- Use full disk encryption to protect the entire contents of the drive or sensitive partitions on the drive.\n- Leverage third-party utilities that interface with self-encrypting drives (SEDs) to provide authentication, while relying on the SED itself for data encryption.\n\n**Example instances.** - The A-FF Repair Station tool is a data recovery utility that can be used for ATA password removal (both High and Maximum level) and firmware area recovery. An adversary with access to this tool could reset the ATA password to bypass this security feature and unlock the hard drive. The adversary could then obtain any data contained within the drive. [REF-702]\n- An adversary gains physical access to the targeted hard drive and installs it into a system that does not support ATA security features. Once the drive is installed in the feature-lacking system, the adversary is able to reset the hard drive password via the BIOS.

The RFC 793 expected behavior is that any TCP segment with an out-of-state Flag sent to an open port is discarded, whereas segments with out-of-state flags sent to closed ports should be handled with a RST in response.

Some operating systems return a positive TCP window size when a RST packet is sent from an open port, and a negative value when the RST originates from a closed port.

Thereafter, messages intended for the target application are handled by the malicious application. Upon receiving a message, the malicious application displays a screen that mimics the target application, thereby convincing the user to enter sensitive information. This type of attack is most often used to obtain sensitive information (e.g., credentials) from the user as they think that they are interacting with the intended target application.\n\n**Mitigations.** - The only known mitigation to this attack is to avoid installing the malicious application on the device. Applications usually have to declare the schemes they wish to register, so detecting this during a review is feasible.\n\n**Related patterns.** - ChildOf: CAPEC-616\n\n## Reference: CAPEC-506 Tapjacking\n**CAPEC-506 Tapjacking (full record).** Abstraction: Standard; Status: Draft; Severity: Low; Likelihood: Low\nAn adversary, through a previously installed malicious application, displays an interface that misleads the user and convinces them to tap on an attacker desired location on the screen. This is often accomplished by overlaying one screen on top of another while giving the appearance of a single interface. There are two main techniques used to accomplish this. The first is to leverage transparent properties that allow taps on the screen to pass through the visible application to an application running in the background. The second is to strategically place a small object (e.g., a button or text field) on top of the visible screen and make it appear to be a part of the underlying application. In both cases, the user is convinced to tap on the screen but does not realize the application that they are interacting with.\n\n**Prerequisites.** - This pattern of attack requires the ability to execute a malicious application on the user's device. This malicious application is used to present the interface to the user and make the attack possible.\n\n**Related patterns.** - ChildOf: CAPEC-173\n\n**Underlying weaknesses.** - CWE-1021 (Improper Restriction of Rendered UI Layers or Frames)\n\n## Reference: CAPEC-507 Physical Theft\n**CAPEC-507 Physical Theft (full record).** Abstraction: Meta; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary gains physical access to a system or device through theft of the item. Possession of a system or device enables a number of unique attacks to be executed and often provides the adversary with an extended timeframe for which to perform an attack. Most protections put in place to secure sensitive information can be defeated when an adversary has physical access and enough time.\n\n**Prerequisites.** - This type of attack requires the existence of a physical target that an adversary believes hosts something of value.\n\n**Mitigations.** - To mitigate this type of attack, physical security techniques such as locks doors, alarms, and monitoring of targets should be implemented.\n\n## Reference: CAPEC-508 Shoulder Surfing\n**CAPEC-508 Shoulder Surfing (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nIn a shoulder surfing attack, an adversary observes an unaware individual's keystrokes, screen content, or conversations with the goal of obtaining sensitive information. One motive for this attack is to obtain sensitive information about the target for financial, personal, political, or other gains. From an insider threat perspective, an additional motive could be to obtain system/application credentials or cryptographic keys. Shoulder surfing attacks are accomplished by observing the content \"over the victim's shoulder\", as implied by the name of this attack.\n\n**Prerequisites.** - The adversary typically requires physical proximity to the target's environment, in order to observe their screen or conversation. This may not be the case if the adversary is able to record the target and obtain sensitive information upon review of the recording.\n\n**Skills required.** - In most cases, an adversary can simply observe and retain the desired information.\n\n**Mitigations.** - Be mindful of your surroundings when discussing or viewing sensitive information in public areas.\n- Pertaining to insider threats, ensure that sensitive information is not displayed to nor discussed around individuals without need-to-know access to said information.\n\n**Consequences.** - None (None)\n\n**Related patterns.** - ChildOf: CAPEC-651\n- CanPrecede: CAPEC-560\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n- CWE-359 (Exposure of Private Personal Information to an Unauthorized Actor)\n\n## Reference: CAPEC-509 Kerberoasting\n**CAPEC-509 Kerberoasting (full record).** Abstraction: Detailed; Status: Stable; Severity: High; Likelihood: n/a\nThrough the exploitation of how service accounts leverage Kerberos authentication with Service Principal Names (SPNs), the adversary obtains and subsequently cracks the hashed credentials of a service account target to exploit its privileges. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. As an authenticated user, the adversary may request Active Directory and obtain a service ticket with portions encrypted via RC4 with the private key of the authenticated account. By extracting the local ticket and saving it disk, the adversary can brute force the hashed value to reveal the target account credentials.\n\n**Prerequisites.** - The adversary requires access as an authenticated user on the system. This attack pattern relates to elevating privileges.\n- The adversary requires use of a third-party credential harvesting tool (e.g., Mimikatz).\n- The adversary requires a brute force tool.\n\n**Skills required.** -\n\n**Execution flow.** . ****: Scan for user accounts with set SPN values\n. ****: Request service tickets\n. ****: Extract ticket and save to disk\n. ****: Crack the encrypted ticket to harvest plain text credentials\n\n**Mitigations.** - Monitor system and domain logs for abnormal access.\n- Employ a robust password policy for service accounts. Passwords should be of adequate length and complexity, and they should expire after a period of time.\n- Employ the principle of least privilege: limit service accounts privileges to what is required for functionality and no more.\n- Enable AES Kerberos encryption (or another stronger encryption algorithm), rather than RC4, where possible.

A poisoned registry can redirect (think phishing for servers) the service requester to a malicious service provider, provide incorrect information in schema or metadata, and delete information about service provider interfaces.\n\n**Prerequisites.** - The attacker must be able to write to resources or redirect access to the service registry.\n\n**Skills required.** - To identify and execute against an over-privileged system interface\n\n**Resources required.** Capability to directly or indirectly modify registry resources\n\n**Execution flow.** . ****: [Find a target SOA or Web Service] The adversary must first indentify a target SOA or Web Service.\n. ****: [Determine desired outcome] Because poisoning a web service registry can have different outcomes, the adversary must decide how they wish to effect the webservice.\n. ****: [Determine if a malicious service needs to be created] If the adversary wishes to redirect requests or responses, they will need to create a malicious service to redirect to.\n. ****: [Poison Web Service Registry] Based on the desired outcome, poison the web service registry. This is done by altering the data at rest in the registry or uploading malicious content by spoofing a service provider.\n\n**Mitigations.** - Design: Enforce principle of least privilege\n- Design: Harden registry server and file access permissions\n- Implementation: Implement communications to and from the registry using secure protocols\n\n**Consequences.** - None (None)\n- None (None)\n- None (None)\n\n**Example instances.** - WS-Addressing provides location and metadata about the service endpoints. An extremely hard to detect attack is an attacker who updates the WS-Addressing header, leaves the standard service request and service provider addressing and header information intact, but adds an additional WS-Addressing Replyto header.

For a better chance of success, an attacker should have more than one hash of the original password, and ideally the whole table.\n- Salt was not used to create the hash of the original password. Otherwise the rainbow tables have to be re-computed, which is very expensive and will make the attack effectively infeasible (especially if salt was added in iterations).\n- The system uses one factor password based authentication.\n\n**Skills required.** - A variety of password cracking tools are available that can leverage a rainbow table. The more difficult part is to obtain the password hash(es) in the first place.\n\n**Resources required.** Rainbow table of password hash chains with the right algorithm used. A password cracking tool that leverages this rainbow table will also be required.

It helps if the attacker knows what hashing algorithm was used by the password system.\n\n**Mitigations.** - Use salt when computing password hashes. That is, concatenate the salt (random bits) with the original password prior to hashing it.

Many applications use temporary files to accelerate processing or to provide records of state across multiple executions of the application. Sometimes, however, these temporary files may end up storing sensitive information. By screening an application's temporary files, an adversary might be able to discover such sensitive information. For example, web browsers often cache content to accelerate subsequent lookups. If the content contains sensitive information then the adversary could recover this from the web cache.\n\n**Prerequisites.** - The target application must utilize temporary files and must fail to adequately secure them against other parties reading them.\n\n**Resources required.** Because some application may have a large number of temporary files and/or these temporary files may be very large, an adversary may need tools that help them quickly search these files for sensitive information.

Sniffing Attacks are similar to Adversary-In-The-Middle attacks (CAPEC-94), but are entirely passive. AiTM attacks are predominantly active and often alter the content of the communications themselves.\n\n**Prerequisites.** - The target data stream must be transmitted on a medium to which the adversary has access.\n\n**Resources required.** The adversary must be able to intercept the transmissions containing the data of interest.

The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified \"From\" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.\n\n**Prerequisites.** - This attack is only applicable when a vulnerable entity associates data or services with an identity.

Session credentials allow users to identify themselves to a service after an initial authentication without needing to resend the authentication information (usually a username and password) with every message. If an attacker is able to forge valid session credentials they may be able to bypass authentication or piggy-back off some other authenticated user's session. This attack differs from Reuse of Session IDs and Session Sidejacking attacks in that in the latter attacks an attacker uses a previous or existing credential without modification while, in a forging attack, the attacker must create their own credential, although it may be based on previously observed credentials.\n\n**Prerequisites.** - The targeted application must use session credentials to identify legitimate users. Session identifiers that remains unchanged when the privilege levels change. Predictable session identifiers.\n\n**Skills required.** - Forge the session credential and reply the request.\n\n**Resources required.** Attackers may require tools to craft messages containing their forged credentials, and ability to send HTTP request to a web application.\n\n**Execution flow.** . ****: [Analyze and Understand Session IDs] The attacker finds that the targeted application use session credentials to identify legitimate users.\n. ****: [Create Session IDs.] Attackers craft messages containing their forged credentials in GET, POST request, HTTP headers or cookies.\n. ****: [Abuse the Victim's Session Credentials] The attacker fixates falsified session ID to the victim when victim access the system. Once the victim has achieved a higher level of privilege, possibly by logging into the application, the attacker can now take over the session using the forged session identifier.\n\n**Mitigations.** - Implementation: Use session IDs that are difficult to guess or brute-force: One way for the attackers to obtain valid session IDs is by brute-forcing or guessing them.

Data copied to the clipboard can be accessed by other applications, such as malware built to exfiltrate or log clipboard contents on a periodic basis. In this way, the adversary aims to garner information to which they are unauthorized.\n\n**Prerequisites.** - The adversary must have a means (i.e., a pre-installed tool or background process) by which to collect data from the clipboard and store it.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n**Prerequisites.** - The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Skills required.** - An attacker can try special characters in the URL and bypass the URL validation.\n- The attacker may write a script to defeat the input filtering mechanism.\n\n**Execution flow.** . ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL. The attacker find out that some characters are not filtered properly.\n. ****: The attacker crafts a malicious URL string request and sends it to the server.\n. ****: The server decodes and interprets the URL string. Unfortunately since the input filtering is not done properly, the special characters have harmful consequences.\n\n**Mitigations.** - Assume all input is malicious.

The adversary could use running code in the context of another process to try to access process's memory, system/network resources, etc. The goal of this attack is to evade detection defenses and escalate privileges by masking the malicious code under an existing legitimate process. Examples of approaches include but not limited to: dynamic-link library (DLL) injection, portable executable injection, thread execution hijacking, ptrace system calls, VDSO hijacking, function hooking, reflective code loading, and more.\n\n**Prerequisites.** - The targeted application fails to verify the integrity of the running process that allows an adversary to execute arbitrary code.\n\n**Skills required.** - Knowledge of how to load malicious code into the memory space of a running process, as well as the ability to have the running process execute this code. For example, with DLL injection, the adversary must know how to load a DLL into the memory space of another running process, and cause this process to execute the code inside of the DLL.\n\n**Execution flow.** . ****: [Determine target process] The adversary determines a process with sufficient privileges that they wish to include code into.\n. ****: [Attempt to include simple code with known output] The adversary attempts to include very simple code into the existing process to determine if the code inclusion worked. The code will differ based on the approach used to include code into an existing process.\n. ****: [Include arbitrary code into existing process] Once an adversary has determined that including code into the existing process is possible, they will include code for a targeted purpose, such as accessing that process's memory.\n\n**Mitigations.** - Prevent unknown or malicious software from loading through using an allowlist policy.\n- Properly restrict the location of the software being used.\n- Leverage security kernel modules providing advanced access control and process restrictions like SELinux.

The goal of eavesdropping is typically to gain unauthorized access to sensitive information about the target for financial, personal, political, or other gains. Eavesdropping is different from a sniffing attack as it does not take place on a network-based communication channel (e.g., IP traffic).

Any transmission medium can theoretically be sniffed if the adversary can examine the contents between the sender and recipient. Sniffing Attacks are similar to Adversary-In-The-Middle attacks (CAPEC-94), but are entirely passive.

This pattern of attack allows the adversary to compromise the application or server via the execution of unauthorized code. An application typically makes calls to functions that are a part of libraries external to the application. These libraries may be part of the operating system or they may be third party libraries.

Once the adversary finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.\n\n**Prerequisites.** - The application uses environment variables.\n- An environment variable exposed to the user is vulnerable to a buffer overflow.\n- The vulnerable environment variable uses untrusted data.\n- Tainted data used in the environment variables is not properly validated. For instance boundary checking is not done before copying the input data to a buffer.\n\n**Skills required.** - An attacker can simply overflow a buffer by inserting a long string into an attacker-modifiable injection vector. The result can be a DoS.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap can require a higher skill level.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. In this attack the adversary looks for an application that loads the content of an environment variable into a buffer.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data.

This may involve detailed knowledge of the target system architecture and kernel.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. Detecting and exploiting a buffer overflow does not require any resources beyond knowledge of and access to the target system.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on.

In IPv6 overlapping(RFC5722) additional steps may be required such as deep packet inspection. The delayed fragments may be mitigated by enforcing a timeout on the transmission to receive all packets by a certain time since the first packet is received.

For example, the server may assume the client filters outbound traffic or that the client performs all price calculations correctly. Moreover, the server must fail to detect when these assumptions are violated by a client.\n\n**Skills required.** - To reverse engineer the client-side code to disable/remove the functionality on the client that the server relies on.\n- The adversary installs a web tool that allows scripts or the DOM model of web-based applications to be modified before they are executed in a browser. GreaseMonkey and Firebug are two examples of such tools.\n\n**Resources required.** The adversary must have access to a client and be able to modify the client behavior, often through reverse engineering. If the server is assuming specific client functionality, this usually means the server only recognizes a specific client application, rather than a broad class of client applications.

If the attacker can remove or modify the logic that controls these calculations, they can return incorrect values to the server. The attacker can use this to make purchases for a fraction of the legitimate cost or otherwise avoid correct billing for activities.\n\n**Prerequisites.** - The targeted server must rely on the client to correctly perform monetary calculations and must fail to detect errors in these calculations.\n\n**Resources required.** The attacker must have access to the client for the targeted service (this step is trivial for most web-based services).

Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser.\n\n**Prerequisites.** - The victim must follow a crafted link that references a scripting file that is mis-typed as a non-executable file.\n- The victim's browser must detect the true type of a mis-labeled scripting file and invoke the appropriate script interpreter without first performing filtering on the content.\n\n**Resources required.** The adversary must have the ability to source the file of the incorrect MIME type containing a script.\n\n**Execution flow.** . ****: [Survey the application for stored user-controllable inputs] Using a browser or an automated tool, an adversary follows all public links and actions on a web site.

Operating System detection is possible because implementations of common protocols (Such as IP or TCP) differ in distinct ways. While the implementation differences are not sufficient to 'break' compatibility with the protocol the differences are detectable because the target will respond in unique ways to specific probing activity that breaks the semantic or logical rules of packet construction for a protocol. Different operating systems will have a unique response to the anomalous input, providing the basis to fingerprint the OS behavior. This type of OS fingerprinting can distinguish between operating system types and versions.\n\n**Prerequisites.** - The ability to monitor and interact with network communications.Access to at least one host, and the privileges to interface with the network interface card.\n\n**Resources required.** Any type of active probing that involves non-standard packet headers requires the use of raw sockets, which is not available on particular operating systems (Microsoft Windows XP SP 2, for example).

Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application will be used to issue spoofed intents.\n\n**Mitigations.** - To limit one's exposure to this type of attack, developers should avoid exporting components unless the component is specifically designed to handle requests from untrusted applications. Developers should be aware that declaring an intent filter will automatically export the component, exposing it to public access. Critical, state-changing actions should not be placed in exported components. If a single component handles both interand intra-application requests, the developer should consider dividing that component into separate components. If a component must be exported (e.g., to receive system broadcasts), then the component should dynamically check the caller's identity prior to performing any operations. Requiring Signature or SignatureOrSystem permissions is an effective way of limiting a component's exposure to a set of trusted applications. Finally, the return values of exported components can also leak private data, so developers should check the caller's identity prior to returning sensitive values.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)"}]}

Email software has become increasingly sophisticated and feature-rich. In addition, email applications are ubiquitous and connected directly to the Web making them ideal targets to launch and propagate attacks. As the user demand for new functionality in email applications grows, they become more like browsers with complex rendering and plug in routines. As more email functionality is included and abstracted from the user, this creates opportunities for attackers. Virtually all email applications do not list email header information by default, however the email header contains valuable attacker vectors for the attacker to exploit particularly if the behavior of the email client application is known. Meta-characters are hidden from the user, but can contain scripts, enumerations, probes, and other attacks against the user's system.\n\n**Prerequisites.** - This attack targets most widely deployed feature rich email applications, including web based email programs.\n\n**Skills required.** - To distribute email\n\n**Execution flow.** . ****: [Identify and characterize metacharacter-processing vulnerabilities in email headers] An attacker creates emails with headers containing various metacharacter-based malicious payloads in order to determine whether the target application processes the malicious content and in what manner it does so.\n. ****: An attacker leverages vulnerabilities identified during the Experiment Phase to inject malicious email headers and cause the targeted email application to exhibit behavior outside of its expected constraints.\n\n**Mitigations.** - Design: Perform validation on email header data\n- Implementation: Implement email filtering solutions on mail server or on MTA, relay server.\n- Implementation: Mail servers that perform strict validation may catch these attacks, because metacharacters are not allowed in many header variables such as dns names\n\n**Consequences.** - None (None)\n\n**Example instances.** - Meta-characters are among the most valuable tools attackers have to deceive users into taking some action on their behalf.

An adversary who uses social engineering to impersonate a tech support worker can have devastating effects on a network. This is an effective attack vector, because it can give an adversary physical access to network computers. It only takes a matter of seconds for someone to compromise a computer with physical access. One of the best technological tools at the disposal of a social engineer, posing as a technical support person, is a USB thumb drive. These are small, easy to conceal, and can be loaded with different payloads depending on what task needs to be done. However, this form of attack does not require physical access as it can also be effectively carried out via phone or email.\n\n**Related patterns.** - ChildOf: CAPEC-407\n\n## Reference: CAPEC-414 Pretexting via Delivery Person\n**CAPEC-414 Pretexting via Delivery Person (full record).** Abstraction: Detailed; Status: Draft; Severity: Low; Likelihood: n/a\nAn adversary engages in pretexting behavior, assuming the role of a delivery person, to solicit information from target persons, or manipulate the target into performing an action that serves the adversary's interests.

The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information.

One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.\n\n**Prerequisites.** - The target must be misconfigured to return a list of a directory's content when it receives a request that ends in a directory name rather than a file name.\n- The adversary must be able to control the path that is requested of the target.\n- The administrator must have failed to properly configure an ACL or has associated an overly permissive ACL with a particular directory.\n- The server version or patch level must not inherently prevent known directory listing attacks from working.\n\n**Skills required.** - To issue the request to URL without given a specific file name\n- To bypass the access control of the directory of listings\n\n**Resources required.** Ability to send HTTP requests to a web application.\n\n**Execution flow.** . ****: [Directory Discovery] Use a method, either manual, scripted, or automated to discover the directories on the server by making requests for directories that may possibly exist.

Negative numbers may be illegal in an application and the application may prevent an attacker from providing them directly, but the application may not consider that adding two positive numbers can create a negative number do to the structure of integer storage formats.\n\n**Prerequisites.** - The target application must have an integer variable for which only some of the possible integer values are expected by the application and where there are no checks on the value of the variable before use.\n- The attacker must be able to manipulate the targeted integer variable such that normal operations result in non-standard values due to the storage structure of integers.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Related patterns.** - ChildOf: CAPEC-153\n\n**Underlying weaknesses.** - CWE-682 (Incorrect Calculation)\n\n## Reference: CAPEC-129 Pointer Manipulation\n**CAPEC-129 Pointer Manipulation (full record).** Abstraction: Meta; Status: Draft; Severity: Medium; Likelihood: n/a\nThis attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.\n\n**Prerequisites.** - The target application must have a pointer variable that the attacker can influence to hold an arbitrary value.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Underlying weaknesses.** - CWE-682 (Incorrect Calculation)\n- CWE-822 (Untrusted Pointer Dereference)\n- CWE-823 (Use of Out-of-range Pointer Offset)\n\n## Reference: CAPEC-13 Subverting Environment Variable Values\n**CAPEC-13 Subverting Environment Variable Values (full record).** Abstraction: Detailed; Status: Stable; Severity: Very High; Likelihood: High\nThe adversary directly or indirectly modifies environment variables used by or controlling the target software. The adversary's goal is to cause the target software to deviate from its expected operation in a manner that benefits the adversary.\n\n**Prerequisites.** - An environment variable is accessible to the user.\n- An environment variable used by the application can be tainted with user supplied data.\n- Input data used in an environment variable is not validated properly.\n- The variables encapsulation is not done properly. For instance setting a variable as public in a class makes it visible and an adversary may attempt to manipulate that variable.\n\n**Skills required.** - In a web based scenario, the client controls the data that it submitted to the server. So anybody can try to send malicious data and try to bypass the authentication mechanism.\n- Some more advanced attacks may require knowledge about protocols and probing technique which help controlling a variable. The malicious user may try to understand the authentication mechanism in order to defeat it.\n\n**Execution flow.** . ****: [Probe target application] The adversary first probes the target application to determine important information about the target. This information could include types software used, software versions, what user input the application consumes, and so on. Most importantly, the adversary tries to determine what environment variables might be used by the underlying software, or even the application itself.\n. ****: [Find user-controlled environment variables] Using the information found by probing the application, the adversary attempts to manipulate any user-controlled environment variables they have found are being used by the application, or suspect are being used by the application, and observe the effects of these changes.

Usually, this attack focuses on memory allocation, but any finite resource on the target could be the attacked, including bandwidth, processing cycles, or other resources. This attack does not attempt to force this allocation through a large number of requests (that would be Resource Depletion through Flooding) but instead uses one or a small number of requests that are carefully formatted to force the target to allocate excessive resources to service this request(s).

One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files.

The larger response that is generated by the 3rd party service is then sent to the target server. By sending a large number of initial requests, the adversary can generate a tremendous amount of traffic directed at the target.

This is one of several TCP 'ping' types. The RFC 793 expected behavior for a service is to respond with a RST 'reset' packet to any unsolicited ACK segment that is not part of an existing connection. So by sending an ACK segment to a port, the adversary can identify that the host is alive by looking for a RST packet. Typically, a remote server will respond with a RST regardless of whether a port is open or closed. In this way, TCP ACK pings cannot discover the state of a remote port because the behavior is the same in either case. The firewall will look up the ACK packet in its state-table and discard the segment because it does not correspond to any active connection. A TCP ACK Ping can be used to discover if a host is alive via RST response packets sent from the host.\n\n**Prerequisites.** - The ability to send an ACK packet to a remote host and identify the response. Creating the ACK packet without building a full connection requires the use of raw sockets. As a result, it is not possible to send a TCP ACK ping from some systems (Windows XP SP 2) without the use of third-party packet drivers like Winpcap. On other systems (BSD, Linux) administrative privileges are required in order to write to the raw socket.\n- The target must employ a stateless firewall that lacks a rule set that rejects unsolicited ACK packets.\n- The adversary requires the ability to craft custom TCP ACK segments for use during network reconnaissance. Sending an ACK ping requires the ability to access \"raw sockets\" in order to create the packets with direct access to the packet header.\n\n**Resources required.** ACK scanning can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language. Packet injection tools are also useful for this purpose. Depending upon the technique used it may also be necessary to sniff the network in order to see the response.\n\n## Reference: CAPEC-298 UDP Ping\n**CAPEC-298 UDP Ping (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary sends a UDP datagram to the remote host to determine if the host is alive. If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target. The goal is to solicit an 'ICMP port unreachable' message from the target, indicating that the host is alive. UDP pings are useful because some firewalls are not configured to block UDP datagrams sent to strange or typically unused ports, like ports in the 65K range. Additionally, while some firewalls may filter incoming ICMP, weaknesses in firewall rule-sets may allow certain types of ICMP (host unreachable, port unreachable) which are useful for UDP ping attempts.\n\n**Prerequisites.** - The adversary requires the ability to send a UDP datagram to a remote host and receive a response.\n- The adversary requires the ability to craft custom UDP Packets for use during network reconnaissance.\n- The target's firewall must not be configured to block egress ICMP messages.\n\n**Resources required.** UDP pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language.

Typical RFC 793 behavior specifies that when a TCP port is open, a host must respond to an incoming SYN \"synchronize\" packet by completing stage two of the 'three-way handshake' - by sending an SYN/ACK in response. When a port is closed, RFC 793 behavior is to respond with a RST \"reset\" packet. This behavior can be used to 'ping' a target to see if it is alive by sending a TCP SYN packet to a port and then looking for a RST or an ACK packet in response.\n\n**Prerequisites.** - The ability to send a TCP SYN packet to a remote target.

The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified \"From\" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.\n\n**Prerequisites.** - This attack is only applicable when a vulnerable entity associates data or services with an identity. Without such an association, there would be no reason to fake the source.\n\n**Resources required.** Resources required vary depending on the nature of the attack.

Phishing and Pharming attacks often attempt to do this so that their attempts to gather sensitive information appear to come from a legitimate source. A Principal Spoof does not use stolen or spoofed authentication credentials, instead relying on the appearance and content of the message to reflect identity.\n\n**Prerequisites.** - The target must associate data or activities with a person's identity and the adversary must be able to modify this identity without detection.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Related patterns.** - ChildOf: CAPEC-151\n\n## Reference: CAPEC-196 Session Credential Falsification through Forging\n**CAPEC-196 Session Credential Falsification through Forging (full record).** Abstraction: Standard; Status: Draft; Severity: Medium; Likelihood: Medium\nAn attacker creates a false but functional session credential in order to gain or usurp access to a service. Session credentials allow users to identify themselves to a service after an initial authentication without needing to resend the authentication information (usually a username and password) with every message. If an attacker is able to forge valid session credentials they may be able to bypass authentication or piggy-back off some other authenticated user's session. This attack differs from Reuse of Session IDs and Session Sidejacking attacks in that in the latter attacks an attacker uses a previous or existing credential without modification while, in a forging attack, the attacker must create their own credential, although it may be based on previously observed credentials.\n\n**Prerequisites.** - The targeted application must use session credentials to identify legitimate users. Session identifiers that remains unchanged when the privilege levels change.

Once the victim has achieved a higher level of privilege, possibly by logging into the application, the attacker can now take over the session using the forged session identifier.\n\n**Mitigations.** - Implementation: Use session IDs that are difficult to guess or brute-force: One way for the attackers to obtain valid session IDs is by brute-forcing or guessing them. By choosing session identifiers that are sufficiently random, brute-forcing or guessing becomes very difficult.

This pattern describes a SQL injection attack with the delivery mechanism being a SOAP message.\n\n**Prerequisites.** - SOAP messages are used as a communication mechanism in the system\n- SOAP parameters are not properly validated at the service provider\n- The service provider does not properly utilize parameter binding when building SQL queries\n\n**Skills required.** - If the attacker is able to gain good understanding of the system's database schema\n- If the attacker has to perform Blind SQL Injection\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Detect Incorrect SOAP Parameter Handling] The attacker tampers with the SOAP message parameters and looks for indications that the tampering caused a change in behavior of the targeted application.\n. ****: [Probe for SQL Injection vulnerability] The attacker injects SQL syntax into vulnerable SOAP parameters identified during the Explore phase to search for unfiltered execution of the SQL syntax in a query.\n. ****: [Inject SQL via SOAP Parameters] The attacker injects SQL via SOAP parameters identified as vulnerable during Explore phase to launch a first or second order SQL injection attack.\n\n**Mitigations.** - Properly validate and sanitize/reject user input at the service provider.\n- Ensure that prepared statements or other mechanism that enables parameter binding is used when accessing the database in a way that would prevent the attackers' supplied data from controlling the structure of the executed query.\n- At the database level, ensure that the database user used by the application in a particular context has the minimum needed privileges to the database that are needed to perform the operation. When possible, run queries against pre-generated views rather than the tables directly.

The malicious website does two things: 1. Contains a hook that intercepts incoming JSON objects, reads their contents and forwards the contents to the server controlled by the attacker (via a new XMLHttpRequest). 2. Uses the script tag with a URL in the source that requests a JSON object from the vulnerable target system. Once the JSON object is transmitted to the victim's browser, the malicious code (as described in step 1) intercepts that JSON object, steals its contents, and forwards to the attacker. […]"}]}

These attacks take advantage of the asymmetric relationship between the processing power used by the client and the processing power used by the server to create a secure connection. In this manner the attacker can make a large number of HTTPS requests on a low provisioned machine to tie up a disproportionately large number of resources on the server. The clients then continue to keep renegotiating the SSL connection. When multiplied by a large number of attacking machines, this attack can result in a crash or loss of service to legitimate users.\n\n**Prerequisites.** - This type of an attack requires the ability to generate a large amount of SSL traffic to send a target server.\n\n**Mitigations.** - To mitigate this type of an attack, an organization can create rule based filters to silently drop connections if too many are attempted in a certain time period.\n\n**Related patterns.** - ChildOf: CAPEC-125\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n\n**ATT&CK mapping.** - 1499.002 (Endpoint Denial of Service:Service Exhaustion Flood)\n\n## Reference: CAPEC-49 Password Brute Forcing\n**CAPEC-49 Password Brute Forcing (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: Medium\nAn adversary tries every possible value for a password until they succeed. A brute force attack, if feasible computationally, will always be successful because it will essentially go through all possible passwords given the alphabet used (lower case letters, upper case letters, numbers, symbols, etc.) and the maximum length of the password.\n\n**Prerequisites.** - An adversary needs to know a username to target.\n- The system uses password based authentication as the one factor authentication mechanism.\n- An application does not have a password throttling mechanism in place. A good password throttling mechanism will make it almost impossible computationally to brute force a password as it may either lock out the user after a certain number of incorrect attempts or introduce time out periods. Both of these would make a brute force attack impractical.\n\n**Skills required.** - A brute force attack is very straightforward. A variety of password cracking tools are widely available.\n\n**Resources required.** A powerful enough computer for the job with sufficient CPU, RAM and HD.

The goal of this attack is to use a relatively few resources to create a large amount of traffic against a target server. To execute this attack, an adversary send a request to a 3rd party service, spoofing the source address to be that of the target server. The larger response that is generated by the 3rd party service is then sent to the target server. By sending a large number of initial requests, the adversary can generate a tremendous amount of traffic directed at the target. The greater the discrepancy in size between the initial request and the final payload delivered to the target increased the effectiveness of this attack.\n\n**Prerequisites.** - This type of an attack requires the existence of a 3rd party service that generates a response that is significantly larger than the request that triggers it.\n\n**Mitigations.** - To mitigate this type of an attack, an organization can attempt to identify the 3rd party services being used in an active attack and blocking them until the attack ends. This can be accomplished by filtering traffic for suspicious message patterns such as a spike in traffic where each response contains the same large block of data. Care should be taken to prevent false positive rates so legitimate traffic isn't blocked.\n\n**Related patterns.** - ChildOf: CAPEC-125\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n\n**ATT&CK mapping.** - 1498.002 (Network Denial of Service:Reflection Amplification)\n\n## Reference: CAPEC-491 Quadratic Data Expansion\n**CAPEC-491 Quadratic Data Expansion (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary exploits macro-like substitution to cause a denial of service situation due to excessive memory being allocated to fully expand the data. The result of this denial of service could cause the application to freeze or crash. This involves defining a very large entity and using it multiple times in a single entity substitution. CAPEC-197 is a similar attack pattern, but it is easier to discover and defend against. This attack pattern does not perform multi-level substitution and therefore does not obviously appear to consume extensive resources.\n\n**Prerequisites.** - This type of attack requires a server that accepts serialization data which supports substitution and parses the data.\n\n**Execution flow.** . ****: [Survey the target] An adversary determines the input data stream that is being processed by a data parser that supports using substituion on the victim's side.\n. ****: [Craft malicious payload] The adversary crafts malicious message containing nested quadratic expansion that completely uses up available server resource.\n. ****: [Send the message] Send the malicious crafted message to the target URL.\n\n**Mitigations.** - Design: Use libraries and templates that minimize unfiltered input. Use methods that limit entity expansion and throw exceptions on attempted entity expansion.\n- Implementation: For XML based data - disable altogether the use of inline DTD schemas when parsing XML objects. If a DTD must be used, normalize, filter and use an allowlist and parse with methods and routines that will detect entity expansion from untrusted sources.\n\n**Consequences.** - None (None)\n\n**Example instances.** - In this example the attacker defines one large entity and refers to it many times.\n- This results in a relatively small message of 100KBs that will expand to a message in the GB range.\n\n**Related patterns.** - ChildOf: CAPEC-230\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n\n## Reference: CAPEC-492 Regular Expression Exponential Blowup\n**CAPEC-492 Regular Expression Exponential Blowup (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.\n\n**Prerequisites.** - This type of an attack requires the ability to identify hosts running a poorly implemented Regex, and the ability to send crafted input to exploit the regular expression.\n\n**Mitigations.** - Test custom written Regex with fuzzing to determine if the Regex is a poor one. Add timeouts to processes that handle the Regex logic. If an evil Regex is found rewrite it as a good Regex.\n\n**Related patterns.** - ChildOf: CAPEC-130\n\n**Underlying weaknesses.** - CWE-400 (Uncontrolled Resource Consumption)\n- CWE-1333 (Inefficient Regular Expression Complexity)\n\n## Reference: CAPEC-493 SOAP Array Blowup\n**CAPEC-493 SOAP Array Blowup (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary may execute an attack on a web service that uses SOAP messages in communication. By sending a very large SOAP array declaration to the web service, the attacker forces the web service to allocate space for the array elements before they are parsed by the XML parser. The attacker message is typically small in size containing a large array declaration of say 1,000,000 elements and a couple of array elements. This attack targets exhaustion of the memory resources of the web service.\n\n**Prerequisites.** - This type of an attack requires the attacker to know the endpoint of the web service, and be able to reach the endpoint with a malicious SOAP message.\n\n**Mitigations.** - Enforce strict schema validation. The schema should enforce a maximum number of array elements. If the number of maximum array elements can't be limited another validation method should be used. One such method could be comparing the declared number of items in the array with the existing number of elements of the array. If these numbers don't match drop the SOAP packet at the web service layer.\n\n**Related patterns.** - ChildOf: CAPEC-130\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)"}]}

An adversary who uses social engineering to impersonate a tech support worker can have devastating effects on a network. This is an effective attack vector, because it can give an adversary physical access to network computers. It only takes a matter of seconds for someone to compromise a computer with physical access. One of the best technological tools at the disposal of a social engineer, posing as a technical support person, is a USB thumb drive. These are small, easy to conceal, and can be loaded with different payloads depending on what task needs to be done.

USB drives present a significant security risk for business and government agencies. Given the ability to integrate wireless functionality into a USB stick, it is possible to design malware that not only steals confidential data, but sniffs the network, or monitor keystrokes, and then exfiltrates the stolen data off-site via a Wireless connection. Also, viruses can be transmitted via the USB interface without the specific use of a memory stick. The attacks from USB devices are often of such sophistication that experts conclude they are not the work of single individuals, but suggest state sponsorship. These attacks can be performed by an adversary with direct access to a target system or can be executed via means such as USB Drop Attacks.\n\n**Prerequisites.** - Some level of physical access to the device being attacked.\n- Information pertaining to the target organization on how to best execute a USB Drop Attack.\n\n**Execution flow.** . ****: [Determine Target System] In certain cases, the adversary will explore an organization's network to determine a specific target machine to exploit based on the information it contains or privileges the main user may possess.\n. ****: [Develop or Obtain malware and install on a USB device] The adversary develops or obtains the malicious software necessary to exploit the target system, which they then install on an external USB device such as a USB flash drive.\n. ****: [Connect or deceive a user into connecting the infected USB device] Once the malware has been placed on an external USB device, the adversary connects the device to the target system or deceives a user into connecting the device to the target system such as in a USB Drop Attack.\n\n**Mitigations.** - Ensure that proper, physical system access is regulated to prevent an adversary from physically connecting a malicious USB device themself.\n- Use anti-virus and anti-malware tools which can prevent malware from executing if it finds its way onto a target system.

The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.\n\n**Prerequisites.** - Certification Authority is using a hash function with insufficient collision resistance to generate the certificate hash to be signed\n\n**Skills required.** - Understanding of how to force a hash collision in X.509 certificates\n- An attacker must be able to craft two X.509 certificates that produce the same hash value\n- Knowledge needed to set up a certification authority\n\n**Resources required.** Knowledge of a certificate authority that uses hashing algorithms with poor collision resistance A valid certificate request and a malicious certificate request with identical hash values\n\n**Execution flow.** . ****: [Craft Certificates] The adversary crafts two different, but valid X.509 certificates that when hashed with an insufficiently collision resistant hashing algorithm would yield the same value.\n. ****: [Send CSR to Certificate Authority] The adversary sends the CSR for one of the certificates to the Certification Authority which uses the targeted hashing algorithm. That request is completely valid and the Certificate Authority issues an X.509 certificate to the adversary which is signed with its private key.\n. ****: [Insert Signed Blob into Unsigned Certificate] The adversary takes the signed blob and inserts it into the second X.509 certificate that the attacker generated. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob is valid in the second certificate.

The adversary crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.\n\n**Prerequisites.** - The target program consumes user-controllable data in the form of tags or variables.\n- The target program does not perform sufficient boundary checking.\n\n**Skills required.** - An adversary can simply overflow a buffer by inserting a long string into an adversary-modifiable injection vector. The result can be a DoS.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap can require a higher skill level.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. Adversaries look for applications or programs that accept formatted files, such as configuration files, as input.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] The adversary will upload the crafted file to the application, causing a buffer overflow.\n\n**Mitigations.** - Use a language or compiler that performs automatic bounds checking.\n- Use an abstraction library to abstract away risky APIs. Not a complete solution.\n- Compiler-based canary mechanisms such as StackGuard, ProPolice and the Microsoft Visual Studio /GS flag. Unless this provides automatic bounds checking, it is not a complete solution.\n- Use OS-level preventative functionality. Not a complete solution.\n- Do not trust input data from user.

Additionally, firewalls often open a port for each UDP connection destined for a service with an open UDP port, meaning the firewalls in essence save the connection state thus the high packet nature of a UDP flood can also overwhelm resources allocated to the firewall.

Since these are legitimate sessions this attack is very difficult to detect.\n\n**Prerequisites.** - This type of an attack requires the ability to generate a large amount of HTTP traffic to send to a target server.\n\n**Mitigations.** - Design: Use a Web Application Firewall (WAF) to help filter out malicious traffic. This can be setup with rules to block IP addresses found in IP reputation databases, which contains lists of known bad IP addresses. Analysts should also monitor when the traffic flow becomes abnormally large, and be able to add on-the-fly rules to block malicious traffic. Special care should be taken to ensure low false positive rates in block rules and functionality should be implemented to allow a legitimate user to resume sending traffic if they have been blocked.\n- Hire a third party provider to implement a Web Application Firewall (WAF) for your application.

In IPv6 overlapping(RFC5722) additional steps may be required such as deep packet inspection. The delayed fragments may be mitigated by enforcing a timeout on the transmission to receive all packets by a certain time since the first packet is received.

IP fragmentation occurs when an IP datagram is larger than the MTU of the route the datagram has to traverse. Typically the attacker will use large UDP packets over 1500 bytes of data which forces fragmentation as ethernet MTU is 1500 bytes. This attack is a variation on a typical UDP flood but it enables more network bandwidth to be consumed with fewer packets.

This exploit relies on the target making multiples passes over the input data and processing a \"layer\" of special characters with each pass. In this manner, the attacker can disguise input that would otherwise be rejected as invalid by concealing it with layers of special/escape characters that are stripped off by subsequent processing steps. The goal is to first discover cases where the input validation layer executes before one or more parsing layers. That is, user input may go through the following logic in an application: <parser1> --> <input validator> --> <parser2>. In such cases, the attacker will need to provide input that will pass through the input validator, but after passing through parser2, will be converted into something that the input validator was supposed to stop.\n\n**Prerequisites.** - User input is used to construct a command to be executed on the target system or as part of the file name.\n- Multiple parser passes are performed on the data supplied by the user.\n\n**Skills required.** - Knowledge of various escaping schemes, such as URL escape encoding and XML escape characters.\n\n**Execution flow.** . ****: [Determine application/system inputs where bypassing input validation is desired] The attacker first needs to determine all of the application's/system's inputs where input validation is being performed and where they want to bypass it.\n. ****: [Determine which character encodings are accepted by the application/system] The attacker then needs to provide various character encodings to the application/system and determine which ones are accepted.

Many developers use signing keys to sign code or hashes of code. When users or applications verify the signatures are accurate they are led to believe that the code came from the owner of the signing key and that the code has not been modified since the signature was applied. If the adversary has extracted the signing credentials then they can use those credentials to sign their own code bundles.

Checksums are used to verify message integrity. They consist of some value based on the value of the message they are protecting. Hash codes are a common checksum mechanism. Both the sender and recipient are able to compute the checksum based on the contents of the message. If the message contents change between the sender and recipient, the sender and recipient will compute different checksum values. Since the sender's checksum value is transmitted with the message, the recipient would know that a modification occurred. In checksum spoofing an adversary modifies the message body and then modifies the corresponding checksum so that the recipient's checksum calculation will match the checksum (created by the adversary) in the message. This would prevent the recipient from realizing that a change occurred.\n\n**Prerequisites.** - The adversary must be able to intercept a message from the sender (keeping the recipient from getting it), modify it, and send the modified message to the recipient.\n- The sender and recipient must use a checksum to protect the integrity of their message and transmit this checksum in a manner where the adversary can intercept and modify it.\n- The checksum value must be computable using information known to the adversary. A cryptographic checksum, which uses a key known only to the sender and recipient, would thwart this attack.\n\n**Resources required.** The adversary must have a utility that can intercept and modify messages between the sender and recipient.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-354 (Improper Validation of Integrity Check Value)\n\n## Reference: CAPEC-146 XML Schema Poisoning\n**CAPEC-146 XML Schema Poisoning (full record).** Abstraction: Detailed; Status: Stable; Severity: High; Likelihood: Low\nAn adversary corrupts or modifies the content of XML schema information passed between a client and server for the purpose of undermining the security of the target.

Ability to replace or redirect access to the modified schema.\n\n**Execution flow.** . ****: [Determine if XML schema is local or remote] Because this attack differs slightly if the target uses remote XML schemas versus local schemas, the adversary first needs to determine which of the two are used.\n. ****: [Gain access to XML schema] The adversary gains access to the XML schema so that they can modify the contents.\n. ****: [Poison XML schema] Once the adversary gains access to the XML schema, they will alter it to achieve a desired effect. Locally, they can simply modify the file. For remote schemas, the adversary will alter the schema in transit by performing an adversary in the middle attack.\n\n**Mitigations.** - Design: Protect the schema against unauthorized modification.\n- Implementation: For applications that use a known schema, use a local copy or a known good repository instead of the schema reference supplied in the XML document. Additionally, ensure that the proper permissions are set on local files to avoid unauthorized modification.\n- Implementation: For applications that leverage remote schemas, use the HTTPS protocol to prevent modification of traffic in transit and to avoid unauthorized modification.\n\n**Consequences.** - None (None)\n- None (None)\n- None (None)\n\n**Example instances.** - XML Schema Poisoning Attacks can often occur locally due to being embedded within the XML document itself or being located on the host within an improperaly protected file.

Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.\n\n**Prerequisites.** - The target must receive and process XML transactions.\n\n**Skills required.** - To send small XML messages\n- To use distributed network to launch the attack\n\n**Resources required.** Transaction generator(s)/source(s) and ability to cause arrival of messages at the target with sufficient rapidity to overload target.

The term content spoofing is most often used to describe modification of web pages hosted by a target to display the adversary's content instead of the owner's content. However, any content can be spoofed, including the content of email messages, file transfers, or the content of other network communication protocols. Content can be modified at the source (e.g. modifying the source file for a web page) or in transit (e.g. intercepting and modifying a message between the sender and recipient). Usually, the adversary will attempt to hide the fact that the content has been modified, but in some cases, such as with web site defacement, this is not necessary. Content Spoofing can lead to malware exposure, financial fraud (if the content governs financial transactions), privacy violations, and other unwanted outcomes.\n\n**Prerequisites.** - The target must provide content but fail to adequately protect it against modification.The adversary must have the means to alter data to which they are not authorized. If the content is to be modified in transit, the adversary must be able to intercept the targeted messages.\n\n**Resources required.** If the content is to be modified in transit, the adversary requires a tool capable of intercepting the target's communication and generating/creating custom packets to impact the communications. In some variants, the targeted content is altered so that all or some of it is redirected towards content published by the attacker (for example, images and frames in the target's web site might be modified to be loaded from a source controlled by the attacker).

This technique requires a terrestrial jammer that is more powerful than the frequencies sent from the satellite.\n\n**Resources required.** A terrestrial satellite jammer with a signal more powerful than that of the satellite attempting to communicate with the target. The adversary must know the location of the target satellite dish.\n\n**Consequences.** - None (None)\n\n**Related patterns.** - ChildOf: CAPEC-195\n\n## Reference: CAPEC-6 Argument Injection\n**CAPEC-6 Argument Injection (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: High\nAn attacker changes the behavior or state of a targeted application through injecting data or command syntax through the targets use of non-validated and non-filtered arguments of exposed services or methods.\n\n**Prerequisites.** - Target software fails to strip all user-supplied input of any content that could cause the shell to perform unexpected actions.\n- Software must allow for unvalidated or unfiltered input to be executed on operating system shell, and, optionally, the system configuration must allow for output to be sent back to client.\n\n**Skills required.** - The attacker has to identify injection vector, identify the operating system-specific commands, and optionally collect the output.\n\n**Resources required.** Ability to communicate synchronously or asynchronously with server. Optionally, ability to capture output directly through synchronous communication or other method such as FTP.\n\n**Execution flow.** . ****: [Discovery of potential injection vectors] Using an automated tool or manual discovery, the attacker identifies services or methods with arguments that could potentially be used as injection vectors (OS, API, SQL procedures, etc.).\n. ****: [1. Attempt variations on argument content] Possibly using an automated tool, the attacker will perform injection variations of the arguments.\n. ****: [Abuse of the application] The attacker injects specific syntax into a particular argument in order to generate a specific malicious effect in the targeted application.\n\n**Mitigations.** - Design: Do not program input values directly on command shell, instead treat user input as guilty until proven innocent. Build a function that takes user input and converts it to applications specific types and values, stripping or filtering out all unauthorized commands and characters in the process.\n- Design: Limit program privileges, so if metacharacters or other methods circumvent program input validation routines and shell access is attained then it is not running under a privileged account. chroot jails create a sandbox for the application to execute in, making it more difficult for an attacker to elevate privilege even in the case that a compromise has occurred. […]\n\n## Reference: CAPEC-60 Reusing Session IDs (aka Session Replay)\n**CAPEC-60 Reusing Session IDs (aka Session Replay) (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: High\nThis attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.\n\n**Prerequisites.** - The target host uses session IDs to keep track of the users.\n- Session IDs are used to control access to resources.\n- The session IDs used by the target host are not well protected from session theft.\n\n**Skills required.** - If an attacker can steal a valid session ID, they can then try to be authenticated with that stolen session ID.\n- More sophisticated attack can be used to hijack a valid session from a user and spoof a legitimate user by reusing their valid session ID.\n\n**Execution flow.** . ****: The attacker interacts with the target host and finds that session IDs are used to authenticate users.\n. ****: The attacker steals a session ID from a valid user.\n. ****: The attacker tries to use the stolen session ID to gain access to the system with the privileges of the session ID's original owner.\n\n**Mitigations.** - Always invalidate a session ID after the user logout.\n- Setup a session time out for the session IDs.\n- Protect the communication between the client and server. For instance it is best practice to use SSL to mitigate adversary in the middle attacks (CAPEC-94).\n- Do not code send session ID with GET method, otherwise the session ID will be copied to the URL. In general avoid writing session IDs in the URLs. URLs can get logged in log files, which are vulnerable to an attacker.\n- Encrypt the session data associated with the session ID.\n- Use multifactor authentication. […]\n\n## Reference: CAPEC-600 Credential Stuffing\n**CAPEC-600 Credential Stuffing (full record).** Abstraction: Standard; Status: Stable; Severity: High; Likelihood: High\nAn adversary tries known username/password combinations against different systems, applications, or services to gain additional authenticated access. Credential Stuffing attacks rely upon the fact that many users leverage the same username/password combination for multiple systems, applications, and services.\n\n**Prerequisites.** - The system/application uses one factor password based authentication, SSO, and/or cloud-based authentication.\n- The system/application does not have a sound password policy that is being enforced.\n- The system/application does not implement an effective password throttling mechanism.\n- The adversary possesses a list of known user accounts and corresponding passwords that may exist on the target.\n\n**Skills required.** - A Credential Stuffing attack is very straightforward.\n\n**Resources required.** A machine with sufficient resources for the job (e.g. CPU, RAM, HD). A known list of username/password combinations. A custom script that leverages the credential list to launch the attack.\n\n**Execution flow.** . ****: [Acquire known credentials] The adversary must obtain known credentials in order to access the target system, application, or service.\n. ****: [Determine target's password policy] Determine the password policies of the target system/application to determine if the known credentials fit within the specified criteria.\n. ****: [Attempt authentication] Try each username/password combination until the target grants access.\n. ****: [Impersonate] An adversary can use successful experiments or authentications to impersonate an authorized user or system or to laterally move within a system or application\n. ****: [Spoofing] Malicious data can be injected into the target system or into a victim user's system by an adversary. The adversary can also pose as a legitimate user to perform social engineering attacks.\n. ****: [Data Exfiltration] The adversary can obtain sensitive data contained within the system or application.\n\n**Mitigations.** - Leverage multi-factor authentication for all authentication services and prior to granting an entity access to the domain network.\n- Create a strong password policy and ensure that your system enforces this policy.

USB drives present a significant security risk for business and government agencies. Given the ability to integrate wireless functionality into a USB stick, it is possible to design malware that not only steals confidential data, but sniffs the network, or monitor keystrokes, and then exfiltrates the stolen data off-site via a Wireless connection. Also, viruses can be transmitted via the USB interface without the specific use of a memory stick. The attacks from USB devices are often of such sophistication that experts conclude they are not the work of single individuals, but suggest state sponsorship. These attacks can be performed by an adversary with direct access to a target system or can be executed via means such as USB Drop Attacks.\n\n**Prerequisites.** - Some level of physical access to the device being attacked.\n- Information pertaining to the target organization on how to best execute a USB Drop Attack.\n\n**Execution flow.** . ****: [Determine Target System] In certain cases, the adversary will explore an organization's network to determine a specific target machine to exploit based on the information it contains or privileges the main user may possess.\n. ****: [Develop or Obtain malware and install on a USB device] The adversary develops or obtains the malicious software necessary to exploit the target system, which they then install on an external USB device such as a USB flash drive.\n. ****: [Connect or deceive a user into connecting the infected USB device] Once the malware has been placed on an external USB device, the adversary connects the device to the target system or deceives a user into connecting the device to the target system such as in a USB Drop Attack.\n\n**Mitigations.** - Ensure that proper, physical system access is regulated to prevent an adversary from physically connecting a malicious USB device themself.\n- Use anti-virus and anti-malware tools which can prevent malware from executing if it finds its way onto a target system.

The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.\n\n**Prerequisites.** - Certification Authority is using a hash function with insufficient collision resistance to generate the certificate hash to be signed\n\n**Skills required.** - Understanding of how to force a hash collision in X.509 certificates\n- An attacker must be able to craft two X.509 certificates that produce the same hash value\n- Knowledge needed to set up a certification authority\n\n**Resources required.** Knowledge of a certificate authority that uses hashing algorithms with poor collision resistance A valid certificate request and a malicious certificate request with identical hash values\n\n**Execution flow.** . ****: [Craft Certificates] The adversary crafts two different, but valid X.509 certificates that when hashed with an insufficiently collision resistant hashing algorithm would yield the same value.\n. ****: [Send CSR to Certificate Authority] The adversary sends the CSR for one of the certificates to the Certification Authority which uses the targeted hashing algorithm. That request is completely valid and the Certificate Authority issues an X.509 certificate to the adversary which is signed with its private key.\n. ****: [Insert Signed Blob into Unsigned Certificate] The adversary takes the signed blob and inserts it into the second X.509 certificate that the attacker generated. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob is valid in the second certificate.

The adversary crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.\n\n**Prerequisites.** - The target program consumes user-controllable data in the form of tags or variables.\n- The target program does not perform sufficient boundary checking.\n\n**Skills required.** - An adversary can simply overflow a buffer by inserting a long string into an adversary-modifiable injection vector. The result can be a DoS.\n- Exploiting a buffer overflow to inject malicious code into the stack of a software system or even the heap can require a higher skill level.\n\n**Execution flow.** . ****: [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. Adversaries look for applications or programs that accept formatted files, such as configuration files, as input.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing.\n. ****: [Overflow the buffer] The adversary will upload the crafted file to the application, causing a buffer overflow.\n\n**Mitigations.** - Use a language or compiler that performs automatic bounds checking.\n- Use an abstraction library to abstract away risky APIs. Not a complete solution.\n- Compiler-based canary mechanisms such as StackGuard, ProPolice and the Microsoft Visual Studio /GS flag. Unless this provides automatic bounds checking, it is not a complete solution.\n- Use OS-level preventative functionality. Not a complete solution.\n- Do not trust input data from user.

This can also be found by looking at parameters in the URL in the navigation bar of the browser\n. ****: [Add Duplicate Parameter Values] Once the adversary has identified what user input is used as HTTP parameters, they will add duplicates to each parameter one by one to observe the results. If the response from the HTTP request shows the duplicate parameter value concatenated with the original parameter value in some way, or simply just the duplicate parameter value, then HPP is possible.\n. ****: [Leverage HPP] Once the adversary has identified how the backend handles duplicate parameters, they will leverage this by polluting the paramters in a way that benefits them. In some cases, hardcoded parameters will be disregarded by the backend. In others, the adversary can bypass a WAF that might only check a parameter before it has been concatenated by the backend, resulting in malicious queries getting through. […]"}]}

The adversary can leverage a race condition by \"running the race\", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.\n\n**Prerequisites.** - A resource is accessed/modified concurrently by multiple processes such that a race condition exists.\n- The adversary has the ability to modify the resource.\n\n**Skills required.** - Being able to \"run the race\" requires basic knowledge of concurrent processing including synchonization techniques.\n\n**Execution flow.** . ****: The adversary explores to gauge what level of access they have.\n. ****: The adversary gains access to a resource on the target host. The adversary modifies the targeted resource. The resource's value is used to determine the next normal execution action.\n. ****: The resource is modified/checked concurrently by multiple processes. By using one of the processes, the adversary is able to modify the value just before it is consumed by a different process. A race condition occurs and is exploited by the adversary to abuse the target host.\n\n**Mitigations.** - Use safe libraries to access resources such as files.\n- Be aware that improper use of access function calls such as chown, tempfile, chmod, etc. can cause a race condition.\n- Use synchronization to control the flow of execution.\n- Use static analysis tools to find race conditions.\n- Pay attention to concurrency problems related to the access of resources.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Example instances.** - The following code illustrates a file that is accessed multiple times by name in a publicly accessible directory.

The server must process queries that it receives without adequately checking or sanitizing queries to ensure they follow these templates.\n\n**Resources required.** The attacker must have sufficient privileges to send queries to the targeted server. A normal client might limit the nature of these queries, so the attacker must either have a modified client or their own application which allows them to modify the expected queries.\n\n**Execution flow.** . ****: [Observe communication and inputs] The fuzzing adversary observes the target system looking for inputs and communications between modules, subsystems, or systems.\n. ****: [Generate fuzzed inputs] Given a fuzzing tool, a target input or protocol, and limits on time, complexity, and input variety, generate a list of inputs to try. Although fuzzing is random, it is not exhaustive. Parameters like length, composition, and how many variations to try are important to get the most cost-effective impact from the fuzzer.\n. ****: [Observe the outcome] Observe the outputs to the inputs fed into the system by fuzzers and see if there are any log or error messages that either provide user/sensitive data or give information about an expected template that could be used to produce this data.\n. ****: [Craft exploit payloads] If the logs did not reveal any user/sensitive data, an adversary will attempt to make the fuzzing inputs form to an expected template\n\n**Example instances.** - A client that queries an employee database might have templates such that the user only supplies the target's name and the template dictates the fields to be returned (location, position in the company, phone number, etc.).

The result is often a denial of service caused by the application being unable to process the corrupted file, but other results, including the disabling of filters or access controls (if the application fails in an unsafe way rather than failing by locking down) or buffer overflows are possible.\n\n**Prerequisites.** - The targeted application must utilize a configuration file that an attacker is able to corrupt. In some cases, the attacker must be able to force the (re-)reading of the corrupted file if the file is normally only consulted at startup.\n- The severity of the attack hinges on how the application responds to the corrupted file. If the application detects the corruption and locks down, this may result in the denial of services provided by the application. If the application fails to detect the corruption, the result could be a more severe denial of service (crash or hang) or even an exploitable buffer overflow. If the application detects the corruption but fails in an unsafe way, this attack could result in the continuation of services but without certain security structures, such as filters or access controls. For example, if the corrupted file configures filters, an unsafe response from an application could result in simply disabling the filtering mechanisms due to the lack of usable configuration data.\n\n**Resources required.** This varies depending on the resources necessary to corrupt the configuration file and the resources needed to force the application to re-read it (if any).\n\n**Related patterns.** - ChildOf: CAPEC-17\n\n**Underlying weaknesses.** - CWE-829 (Inclusion of Functionality from Untrusted Control Sphere)\n\n## Reference: CAPEC-264 DEPRECATED: Environment Variable Manipulation\n**CAPEC-264 DEPRECATED: Environment Variable Manipulation (full record).** Abstraction: Meta; Status: Deprecated; Severity: n/a; Likelihood: n/a\nThis attack pattern has been deprecated as it is a duplicate of the existing attack pattern \"CAPEC-13: Subverting Environment Variable Values\".

UDDI, ebXML, and similar standards are used to identify businesses in e-business transactions. Among other things, they identify a particular participant, WSDL information for SOAP transactions, and supported communication protocols, including security protocols. By spoofing one of these messages an attacker could impersonate a legitimate business in a transaction or could manipulate the protocols used between a client and business. This could result in disclosure of sensitive information, loss of message integrity, or even financial fraud.\n\n**Prerequisites.** - The targeted business's UDDI or ebXML information must be served from a location that the attacker can spoof or compromise or the attacker must be able to intercept and modify unsecured UDDI/ebXML messages in transit.\n\n**Resources required.** The attacker must be able to force the target user to accept their spoofed UDDI or ebXML message as opposed to the a message associated with a legitimate company.

XML Routing Detour Attacks are Adversary in the Middle type attacks (CAPEC-94). The attacker compromises or inserts an intermediate system in the processing of the XML message. For example, WS-Routing can be used to specify a series of nodes or intermediaries through which content is passed. If any of the intermediate nodes in this route are compromised by an attacker they could be used for a routing detour attack. From the compromised system the attacker is able to route the XML process to other nodes of their choice and modify the responses so that the normal chain of processing is unaware of the interception. This system can forward the message to an outside entity and hide the forwarding and processing from the legitimate processing systems by altering the header information.\n\n**Prerequisites.** - The targeted system must have multiple stages processing of XML content.\n\n**Skills required.** - To inject a bogus node in the XML routing table\n\n**Resources required.** The attacker must be able to insert or compromise a system into the processing path for the transaction.\n\n**Execution flow.** . ****: [Survey the target] Using command line or an automated tool, an attacker records all instances of web services to process XML requests.\n. ****: [Identify SOAP messages that have multiple state processing.] Inspect instance to see whether the XML processing has multiple stages or not.\n. ****: [Launch an XML routing detour attack] The attacker injects a bogus routing node (using a WS-Referral service) into the routing table of the XML header of the SOAP message identified in the Explore phase.

This information could include types software used, software versions, what user input the application consumes, and so on. Most importantly, the adversary tries to determine what environment variables might be used by the underlying software, or even the application itself.\n. ****: [Find user-controlled environment variables] Using the information found by probing the application, the adversary attempts to manipulate any user-controlled environment variables they have found are being used by the application, or suspect are being used by the application, and observe the effects of these changes. If the adversary notices any significant changes to the application, they will know that a certain environment variable is important to the application behavior and indicates a possible attack vector.\n. ****: [Manipulate user-controlled environment variables] The adversary manipulates the found environment variable(s) to abuse the normal flow of processes or to gain access to privileged resources.\n\n**Mitigations.** - Protect environment variables against unauthorized read and write access.

Usually, this attack focuses on memory allocation, but any finite resource on the target could be the attacked, including bandwidth, processing cycles, or other resources. This attack does not attempt to force this allocation through a large number of requests (that would be Resource Depletion through Flooding) but instead uses one or a small number of requests that are carefully formatted to force the target to allocate excessive resources to service this request(s). Often this attack takes advantage of a bug in the target to cause the target to allocate resources vastly beyond what would be needed for a normal request.\n\n**Prerequisites.** - The target must accept service requests from the attacker and the adversary must be able to control the resource allocation associated with this request to be in excess of the normal allocation.

For example, in some applications, adding a --debug switch causes debugging information to be displayed, which can sometimes reveal sensitive processing or configuration information to an attacker.

Web-mail servers often sit between the Internet and the IMAP or SMTP mail server. User requests are received by the web-mail servers which then query the back-end mail server for the requested information and return this response to the user. In an IMAP/SMTP command injection attack, mail-server commands are embedded in parts of the request sent to the web-mail server. If the web-mail server fails to adequately sanitize these requests, these commands are then sent to the back-end mail server when it is queried by the web-mail server, where the commands are then executed. This attack can be especially dangerous since administrators may assume that the back-end server is protected against direct Internet access and therefore may not secure it adequately against the execution of malicious commands.\n\n**Prerequisites.** - The target environment must consist of a web-mail server that the attacker can query and a back-end mail server. The back-end mail server need not be directly accessible to the attacker.\n- The web-mail server must fail to adequately sanitize fields received from users and passed on to the back-end mail server.\n- The back-end mail server must not be adequately secured against receiving malicious commands from the web-mail server.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

Mobile device users often Root/Jailbreak their devices in order to gain administrative control over the mobile operating system and/or to install third-party mobile applications that are not provided by authorized application stores (e.g. Google Play Store and Apple App Store). Adversaries may further leverage these capabilities to escalate privileges or bypass access control on legitimate applications. Although many mobile applications check if a mobile device is Rooted/Jailbroken prior to authorized use of the application, adversaries may be able to \"hook\" code in order to circumvent these checks.

Mobile device users often Root/Jailbreak their devices in order to gain administrative control over the mobile operating system and/or to install third-party mobile applications that are not provided by authorized application stores (e.g. Google Play Store and Apple App Store). Rooting/Jailbreaking a mobile device also provides users with access to system debuggers and disassemblers, which can be leveraged to exploit applications by dumping the application's memory at runtime in order to remove or bypass signature verification methods. This further allows the adversary to evade Root/Jailbreak detection mechanisms, which can result in execution of administrative commands, obtaining confidential data, impersonating legitimate users of the application, and more.\n\n**Prerequisites.** - A debugger must be able to be inserted into the targeted application.\n\n**Skills required.** - Knowledge about Root/Jailbreak detection and evasion techniques.\n- Knowledge about runtime debugging.\n\n**Resources required.** The adversary must have a Rooted/Jailbroken mobile device with debugging capabilities.\n\n**Execution flow.** . ****: [Identify application with attack potential] The adversary searches for and identifies a mobile application that could be exploited for malicious purposes (e.g. banking, voting, or medical applications).\n. ****: [Debug the target application] The adversary inserts the debugger into the program entry point of the mobile application, after the application's signature has been identified, to dump its memory contents.\n. ****: [Remove application signature verification methods] Remove signature verification methods from the decrypted code and resign the application with a self-signed certificate.\n. ****: [Execute the application and evade Root/Jailbreak detection methods] The application executes with the self-signed certificate, while believing it contains a trusted certificate.

If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.\n\n**Prerequisites.** - Server must be running a web application that processes HTTP requests.\n\n**Skills required.** - The adversary will have to detect the vulnerability through an intermediary service or specify maliciously crafted URLs and analyze the server response.\n- The adversary will be required to access internal resources, extract information, or leverage the services running on the server to perform unauthorized actions such as traversing the local network or routing a reflected TCP DDoS through them.\n\n**Resources required.** [None] No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Find target application] Find target web application that accepts a user input and retrieves data from the server\n. ****: [Examine existing application requests] Examine HTTP/GET requests to view the URL query format.

This is one of several TCP 'ping' types. The RFC 793 expected behavior for a service is to respond with a RST 'reset' packet to any unsolicited ACK segment that is not part of an existing connection. So by sending an ACK segment to a port, the adversary can identify that the host is alive by looking for a RST packet. Typically, a remote server will respond with a RST regardless of whether a port is open or closed. In this way, TCP ACK pings cannot discover the state of a remote port because the behavior is the same in either case. The firewall will look up the ACK packet in its state-table and discard the segment because it does not correspond to any active connection. A TCP ACK Ping can be used to discover if a host is alive via RST response packets sent from the host.\n\n**Prerequisites.** - The ability to send an ACK packet to a remote host and identify the response. Creating the ACK packet without building a full connection requires the use of raw sockets. As a result, it is not possible to send a TCP ACK ping from some systems (Windows XP SP 2) without the use of third-party packet drivers like Winpcap. On other systems (BSD, Linux) administrative privileges are required in order to write to the raw socket.\n- The target must employ a stateless firewall that lacks a rule set that rejects unsolicited ACK packets.\n- The adversary requires the ability to craft custom TCP ACK segments for use during network reconnaissance. Sending an ACK ping requires the ability to access \"raw sockets\" in order to create the packets with direct access to the packet header.\n\n**Resources required.** ACK scanning can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language. Packet injection tools are also useful for this purpose. Depending upon the technique used it may also be necessary to sniff the network in order to see the response.\n\n## Reference: CAPEC-298 UDP Ping\n**CAPEC-298 UDP Ping (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary sends a UDP datagram to the remote host to determine if the host is alive. If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target. The goal is to solicit an 'ICMP port unreachable' message from the target, indicating that the host is alive. UDP pings are useful because some firewalls are not configured to block UDP datagrams sent to strange or typically unused ports, like ports in the 65K range. Additionally, while some firewalls may filter incoming ICMP, weaknesses in firewall rule-sets may allow certain types of ICMP (host unreachable, port unreachable) which are useful for UDP ping attempts.\n\n**Prerequisites.** - The adversary requires the ability to send a UDP datagram to a remote host and receive a response.\n- The adversary requires the ability to craft custom UDP Packets for use during network reconnaissance.\n- The target's firewall must not be configured to block egress ICMP messages.\n\n**Resources required.** UDP pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language.

Typical RFC 793 behavior specifies that when a TCP port is open, a host must respond to an incoming SYN \"synchronize\" packet by completing stage two of the 'three-way handshake' - by sending an SYN/ACK in response. When a port is closed, RFC 793 behavior is to respond with a RST \"reset\" packet. This behavior can be used to 'ping' a target to see if it is alive by sending a TCP SYN packet to a port and then looking for a RST or an ACK packet in response.\n\n**Prerequisites.** - The ability to send a TCP SYN packet to a remote target. Depending upon the operating system, the ability to craft SYN packets may require elevated privileges.\n\n**Skills required.** - The adversary needs to know how to craft and send protocol commands from the command line or within a tool.\n\n**Resources required.** SYN pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language.

An adversary can intentionally introduce leading \"ghost\" characters (extra characters that don't affect the validity of the request at the API layer) that enable the input to pass the filters and therefore process the adversary's input. This occurs when the targeted API will accept input data in several syntactic forms and interpret it in the equivalent semantic way, while the filter does not take into account the full spectrum of the syntactic forms acceptable to the targeted API.\n\n**Prerequisites.** - The targeted API must ignore the leading ghost characters that are used to get past the filters for the semantics to be the same.\n\n**Skills required.** - The ability to make an API request, and knowledge of \"ghost\" characters that will not be filtered by any input validation. These \"ghost\" characters must be known to not affect the way in which the request will be interpreted.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser, an automated tool or by inspecting the application, an adversary records all entry points to the application.\n. ****: [Probe entry points to locate vulnerabilities] The adversary uses the entry points gathered in the \"Explore\" phase as a target list and injects various leading 'Ghost' character sequences to determine how to application filters them.\n. ****: [Bypass input filtering] Using what the adversary learned about how the application filters input data, they craft specific input data that bypasses the filter. This can lead to directory traversal attacks, arbitrary shell command execution, corruption of files, etc.\n\n**Mitigations.** - Use an allowlist rather than a denylist input validation.\n- Canonicalize all data prior to validation.\n- Take an iterative approach to input validation (defense in depth).

By using a privleged thread to do their bidding, adversaries can evade process-based detection that would stop an attack that creates a new process. This can lead to an adversary gaining access to the process's memory and can also enable elevated privileges. The most common way to perform this attack is by suspending an existing thread and manipulating its memory.\n\n**Prerequisites.** - The application in question employs a threaded model of execution with the threads operating at, or having the ability to switch to, a higher privilege level than normal users\n- In order to feasibly execute this class of attacks, the adversary must have the ability to hijack a privileged thread. This ability includes, but is not limited to, modifying environment variables that affect the process the thread belongs to, or calling native OS calls that can suspend and alter process memory. This does not preclude network-based attacks, but makes them conceptually more difficult to identify and execute.\n\n**Skills required.** - Hijacking a thread involves knowledge of how processes and threads function on the target platform, the design of the target application as well as the ability to identify the primitives to be used or manipulated to hijack the thread.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack. The adversary needs to be able to latch onto a privileged thread. The adversary does, however, need to be able to program, compile, and link to the victim binaries being executed so that it will turn control of a privileged thread over to the adversary's malicious code. This is the case even if the adversary conducts the attack remotely.\n\n**Execution flow.** . ****: [Determine target thread] The adversary determines the underlying system thread that is subject to user-control\n. ****: [Gain handle to thread] The adversary then gains a handle to a process thread.\n.

Methods that take scripted instructions (or references to scripted instructions) can be very flexible and powerful. However, if an attacker can specify the script that serves as input to these methods they can gain access to a great deal of functionality. For example, HTML pages support tags that allow scripting languages to be embedded in the page and then interpreted by the receiving web browser. If the content provider is malicious, these scripts can compromise the client application. Some applications may even execute the scripts under their own identity (rather than the identity of the user providing the script) which can allow attackers to perform activities that would otherwise be denied to them.\n\n**Prerequisites.** - The target application must include the use of APIs that execute scripts.\n- The target application must allow the attacker to provide some or all of the arguments to one of these script interpretation methods and must fail to adequately filter these arguments for dangerous or unwanted script commands.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Identify API] Discover an API of interest by exploring application documentation or observing responses to API calls\n. ****: [Test simple script] Adversaries will attempt to give a smaller script as input to the API, such as simply printing to the console, to see if the attack is viable.\n. ****: [Give malicious scripting instructions to API] Adversaries will now craft custom scripts to do malicious behavior.

Most often, this involves manipulation of the routing of network messages so, instead of arriving at their proper destination, they are directed towards an entity of the attackers' choosing, usually a server controlled by the attacker. The victim is often unaware that their messages are not being processed correctly. For example, a targeted client may believe they are connecting to their own bank but, in fact, be connecting to a Pharming site controlled by the attacker which then collects the user's login information in order to hijack the actual bank account.\n\n**Prerequisites.** - The targeted client must access the site via infrastructure that the attacker has co-opted and must fail to adequately verify that the communication channel is operating correctly (e.g. by verifying that they are, in fact, connected to the site they intended.)\n\n**Resources required.** The attacker must be able to corrupt the infrastructure used by the client.

For example, eShoplifting is a data manipulation attack against an on-line merchant during a purchasing transaction. The manipulation of price, discount or quantity fields in the transaction message allows the adversary to acquire items at a lower cost than the merchant intended. The adversary performs a normal purchasing transaction but edits hidden fields within the HTML form response that store price or other information to give themselves a better deal. The merchant then uses the modified pricing information in calculating the cost of the selected items.\n\n**Prerequisites.** - The targeted site must contain hidden fields to be modified.\n- The targeted site must not validate the hidden fields with backend processing.\n\n**Resources required.** The adversary must have the ability to modify hidden fields by editing the HTTP response to the server.\n\n**Execution flow.** . ****: [Probe target web application] The adversary first probes the target web application to find all possible pages that can be visited on the website.\n. ****: [Find hidden fields] Once the web application has been traversed, the adversary looks for all hidden HTML fields present in the client-side.\n. ****: [Send modified hidden fields to server-side] Once the adversary has found hidden fields in the client-side, they will modify the values of these hidden fields one by one and then interact with the web application so that this data is sent to the server-side.

The quality of the targeted email is usually enhanced by appearing to come from a known or trusted entity. If the email account of some trusted entity has been compromised the message may be digitally signed. The message will contain information specific to the targeted users that will enhance the probability that they will follow the URL to the compromised site. For example, the message may indicate knowledge of the targets employment, residence, interests, or other information that suggests familiarity. As soon as the user follows the instructions in the message, the attack proceeds as a standard Phishing attack.\n\n**Prerequisites.** - None.

Mobile Phishing is a variation of the Phishing social engineering technique where the attack is initiated via a text or SMS message, rather than email. The user is enticed to provide information or visit a compromised web site via this message. Apart from the manner in which the attack is initiated, the attack proceeds as a standard Phishing attack.\n\n**Prerequisites.** - An adversary needs mobile phone numbers to initiate contact with the victim.\n- An adversary needs to correctly guess the entity with which the victim does business and impersonate it. Most of the time phishers just use the most popular banks/services and send out their \"hooks\" to many potential victims.\n- An adversary needs to have a sufficiently compelling call to action to prompt the user to take action.\n- The replicated website needs to look extremely similar to the original website and the URL used to get to that website needs to look like the real URL of the said business entity.\n\n**Skills required.** - Basic knowledge about websites: obtaining them, designing and implementing them, etc.\n\n**Resources required.** Either mobile phone or access to a web resource that allows text messages to be sent to mobile phones. Resources needed for regular Phishing attack.\n\n**Execution flow.** . ****: [Obtain domain name and certificate to spoof legitimate site] This optional step can be used to help the adversary impersonate the legitimate site more convincingly. The adversary can use homograph or similar attacks to convince users that they are using the legitimate website. Note that this step is not required for phishing attacks, and many phishing attacks simply supply URLs containing an IP address and no SSL certificate.\n. ****: [Explore legitimate website and create duplicate] An adversary creates a website (optionally at a URL that looks similar to the original URL) that closely resembles the website that they are trying to impersonate. That website will typically have a login form for the victim to put in their authentication credentials.

Attackers use this class of attacks to cause applications to enter unstable states, overwrite or expose sensitive information, and even execute arbitrary code with the application's privileges. This class of attacks differs from attacks on configuration information (even if file-based) in that file manipulation causes the file processing to result in non-standard behaviors, such as buffer overflows or use of the incorrect interpreter. Configuration attacks rely on the application interpreting files correctly in order to insert harmful configuration information. Likewise, resource location attacks rely on controlling an application's ability to locate files, whereas File Manipulation attacks do not require the application to look in a non-default location, although the two classes of attacks are often combined.\n\n**Prerequisites.** - The target must use the affected file without verifying its integrity.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

Normal Microsoft utilities do not show the presence of an ADS stream attached to a file. The additional space for the ADS is not recorded in the displayed file size. The additional space for ADS is accounted for in the used space on the volume. An ADS can be any type of file. ADS are copied by standard Microsoft utilities between NTFS volumes. ADS can be used by an attacker or intruder to hide tools, scripts, and data from detection by normal system utilities. Many anti-virus programs do not check for or scan ADS. Windows Vista does have a switch (-R) on the command line DIR command that will display alternate streams.\n\n**Prerequisites.** - The target must be running the Microsoft NTFS file system.\n\n**Resources required.** The attacker must have command line or programmatic access to the target's files system with write/read permissions.\n\n**Mitigations.** - Design: Use FAT file systems which do not support Alternate Data Streams.\n- Implementation: Use Vista dir with the -R switch or utility to find Alternate Data Streams and take appropriate action with those discovered.\n- Implementation: Use products that are Alternate Data Stream aware for virus scanning and system security operations.\n\n**Related patterns.** - ChildOf: CAPEC-636\n\n**Underlying weaknesses.** - CWE-212 (Improper Removal of Sensitive Information Before Storage or Transfer)\n- CWE-69 (Improper Handling of Windows ::DATA Alternate Data Stream)\n\n## Reference: CAPEC-169 Footprinting\n**CAPEC-169 Footprinting (full record).** Abstraction: Meta; Status: Stable; Severity: Very Low; Likelihood: High\nAn adversary engages in probing and exploration activities to identify constituents and properties of the target.\n\n**Prerequisites.** - An application must publicize identifiable information about the system or application through voluntary or involuntary means. Certain identification details of information systems are visible on communication networks (e.g., if an adversary uses a sniffer to inspect the traffic) due to their inherent structure and protocol standards. Any system or network that can be detected can be footprinted. However, some configuration choices may limit the useful information that can be collected during a footprinting attack.\n\n**Skills required.** - The adversary knows how to send HTTP request, run the scan tool.\n\n**Resources required.** The adversary requires a variety of tools to collect information about the target. These include port/network scanners and tools to analyze responses from applications to determine version and configuration information.

USB drives present a significant security risk for business and government agencies. Given the ability to integrate wireless functionality into a USB stick, it is possible to design malware that not only steals confidential data, but sniffs the network, or monitor keystrokes, and then exfiltrates the stolen data off-site via a Wireless connection. Also, viruses can be transmitted via the USB interface without the specific use of a memory stick. The attacks from USB devices are often of such sophistication that experts conclude they are not the work of single individuals, but suggest state sponsorship. These attacks can be performed by an adversary with direct access to a target system or can be executed via means such as USB Drop Attacks.\n\n**Prerequisites.** - Some level of physical access to the device being attacked.\n- Information pertaining to the target organization on how to best execute a USB Drop Attack.\n\n**Execution flow.** . ****: [Determine Target System] In certain cases, the adversary will explore an organization's network to determine a specific target machine to exploit based on the information it contains or privileges the main user may possess.\n. ****: [Develop or Obtain malware and install on a USB device] The adversary develops or obtains the malicious software necessary to exploit the target system, which they then install on an external USB device such as a USB flash drive.\n. ****: [Connect or deceive a user into connecting the infected USB device] Once the malware has been placed on an external USB device, the adversary connects the device to the target system or deceives a user into connecting the device to the target system such as in a USB Drop Attack.\n\n**Mitigations.** - Ensure that proper, physical system access is regulated to prevent an adversary from physically connecting a malicious USB device themself.\n- Use anti-virus and anti-malware tools which can prevent malware from executing if it finds its way onto a target system.

The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.\n\n**Prerequisites.** - Certification Authority is using a hash function with insufficient collision resistance to generate the certificate hash to be signed\n\n**Skills required.** - Understanding of how to force a hash collision in X.509 certificates\n- An attacker must be able to craft two X.509 certificates that produce the same hash value\n- Knowledge needed to set up a certification authority\n\n**Resources required.** Knowledge of a certificate authority that uses hashing algorithms with poor collision resistance A valid certificate request and a malicious certificate request with identical hash values\n\n**Execution flow.** . ****: [Craft Certificates] The adversary crafts two different, but valid X.509 certificates that when hashed with an insufficiently collision resistant hashing algorithm would yield the same value.\n. ****: [Send CSR to Certificate Authority] The adversary sends the CSR for one of the certificates to the Certification Authority which uses the targeted hashing algorithm. That request is completely valid and the Certificate Authority issues an X.509 certificate to the adversary which is signed with its private key.\n. ****: [Insert Signed Blob into Unsigned Certificate] The adversary takes the signed blob and inserts it into the second X.509 certificate that the attacker generated.

A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.\n\n**Prerequisites.** - This type of an attack requires the ability to identify hosts running a poorly implemented Regex, and the ability to send crafted input to exploit the regular expression.\n\n**Mitigations.** - Test custom written Regex with fuzzing to determine if the Regex is a poor one.

The attacker message is typically small in size containing a large array declaration of say 1,000,000 elements and a couple of array elements. This attack targets exhaustion of the memory resources of the web service.\n\n**Prerequisites.** - This type of an attack requires the attacker to know the endpoint of the web service, and be able to reach the endpoint with a malicious SOAP message.\n\n**Mitigations.** - Enforce strict schema validation. The schema should enforce a maximum number of array elements. If the number of maximum array elements can't be limited another validation method should be used. One such method could be comparing the declared number of items in the array with the existing number of elements of the array.

The essential part of the guidance is creating the following rule \"IF FO=1 and PROTOCOL=TCP then DROP PACKET\" as this mitigated both tiny fragment and overlapping fragment attacks in IPv4. In IPv6 overlapping(RFC5722) additional steps may be required such as deep packet inspection. The delayed fragments may be mitigated by enforcing a timeout on the transmission to receive all packets by a certain time since the first packet is received. According to RFC2460 IPv6 implementations should enforce a rule to discard all fragments if the fragments are not ALL received within 60 seconds of the FIRST arriving fragment.\n\n**Related patterns.** - ChildOf: CAPEC-130\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)\n- CWE-404 (Improper Resource Shutdown or Release)\n\n## Reference: CAPEC-495 UDP Fragmentation\n**CAPEC-495 UDP Fragmentation (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker may execute a UDP Fragmentation attack against a target server in an attempt to consume resources such as bandwidth and CPU. IP fragmentation occurs when an IP datagram is larger than the MTU of the route the datagram has to traverse. Typically the attacker will use large UDP packets over 1500 bytes of data which forces fragmentation as ethernet MTU is 1500 bytes. This attack is a variation on a typical UDP flood but it enables more network bandwidth to be consumed with fewer packets.

An implicit intent sent from a trusted application can be received by any application that has declared an appropriate intent filter. If the intent is not protected by a permission that the malicious application lacks, then the attacker can gain access to the data contained within the intent. Further, the intent can be either blocked from reaching the intended destination, or modified and potentially forwarded along.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application is used to intercept implicit intents.\n\n**Execution flow.** . ****: [Find an android application that uses implicit intents] Since this attack only works on android applications that use implicit intents, rather than explicit intents, an adversary must first identify an app that uses implicit intents. They must also determine what the contents of the intents being sent are such that a malicious application can get sent these intents.\n. ****: [Create a malicious app] The adversary must create a malicious android app meant to intercept implicit intents from a target application\n. ****: [Get user to download malicious app] The adversary must get a user using the targeted app to download the malicious app by any means necessary\n. ****: [Intercept Implicit Intents] Once the malicious app is downloaded, the android device will forward any implicit intents from the target application to the malicious application, allowing the adversary to gaina access to the contents of the intent. The adversary can proceed with any attack using the contents of the intent.\n\n**Mitigations.** - To mitigate this type of an attack, explicit intents should be used whenever sensitive data is being sent. An explicit intent is delivered to a specific application as declared within the intent, whereas the Android operating system determines who receives an implicit intent which could potentially be a malicious application.

Many developers use signing keys to sign code or hashes of code. When users or applications verify the signatures are accurate they are led to believe that the code came from the owner of the signing key and that the code has not been modified since the signature was applied. If the adversary has extracted the signing credentials then they can use those credentials to sign their own code bundles. Users or tools that verify the signatures attached to the code will likely assume the code came from the legitimate developer and install or run the code, effectively allowing the adversary to execute arbitrary code on the victim's computer. This differs from CAPEC-673, because the adversary is performing the code signing.\n\n**Prerequisites.** - The targeted developer must use a signing key to sign code bundles. (Note that not doing this is not a defense - it only means that the adversary does not need to steal the signing key before forging code bundles in the developer's name.)\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: The adversary first attempts to obtain a digital certificate in order to sign their malware or tools. This certificate could be stolen, created by the adversary, or acquired normally through a certificate authority.\n. ****: Based on the type of certificate obtained, the adversary will create a goal for their attack. This is either a broad or targeted attack. If an adversary was able to steal a certificate from a targeted organization, they could target this organization by pretending to have legitimate code signed by them. In other cases, the adversary would simply sign their malware and pose as legitimate software such that any user might trust it. This is the more broad approach\n. ****: The adversary creates their malware and signs it with the obtained digital certificate.

Moreover, the server must fail to detect when these assumptions are violated by a client.\n\n**Skills required.** - To reverse engineer the client-side code to disable/remove the functionality on the client that the server relies on.\n- The adversary installs a web tool that allows scripts or the DOM model of web-based applications to be modified before they are executed in a browser. GreaseMonkey and Firebug are two examples of such tools.\n\n**Resources required.** The adversary must have access to a client and be able to modify the client behavior, often through reverse engineering. If the server is assuming specific client functionality, this usually means the server only recognizes a specific client application, rather than a broad class of client applications. Reverse engineering tools would likely be necessary.\n\n**Execution flow.** . ****: [Probing] The adversary probes, through brute-forcing, reverse-engineering or other similar means, the functionality on the client that server assumes to be present and trustworthy.\n. ****: [Determine which functionality to disable or remove] The adversary tries to determine which functionality to disable or remove through reverse-engineering from the list of functionality identified in the Explore phase.\n. ****: [Disable or remove the critical functionality from the client code] Once the functionality has been determined, the adversary disables or removes the critical functionality from the client code to perform malicious actions that the server believes are prohibited.\n\n**Mitigations.** - Design: For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side.\n- Design: Ship client-side application with integrity checks (code signing) when possible.\n- Design: Use obfuscation and other techniques to prevent reverse engineering the client code.

A server may rely on a client to correctly compute monetary information. For example, a server might supply a price for an item and then rely on the client to correctly compute the total cost of a purchase given the number of items the user is buying. If the attacker can remove or modify the logic that controls these calculations, they can return incorrect values to the server. The attacker can use this to make purchases for a fraction of the legitimate cost or otherwise avoid correct billing for activities.\n\n**Prerequisites.** - The targeted server must rely on the client to correctly perform monetary calculations and must fail to detect errors in these calculations.\n\n**Resources required.** The attacker must have access to the client for the targeted service (this step is trivial for most web-based services).

The adversary tricks the victim into accessing a URL that responds with the script file. Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser.\n\n**Prerequisites.** - The victim must follow a crafted link that references a scripting file that is mis-typed as a non-executable file.\n- The victim's browser must detect the true type of a mis-labeled scripting file and invoke the appropriate script interpreter without first performing filtering on the content.\n\n**Resources required.** The adversary must have the ability to source the file of the incorrect MIME type containing a script.\n\n**Execution flow.** . ****: [Survey the application for stored user-controllable inputs] Using a browser or an automated tool, an adversary follows all public links and actions on a web site. They record all areas that allow a user to upload content through an HTTP POST request.

This is one of several TCP 'ping' types. The RFC 793 expected behavior for a service is to respond with a RST 'reset' packet to any unsolicited ACK segment that is not part of an existing connection. So by sending an ACK segment to a port, the adversary can identify that the host is alive by looking for a RST packet. Typically, a remote server will respond with a RST regardless of whether a port is open or closed. In this way, TCP ACK pings cannot discover the state of a remote port because the behavior is the same in either case. The firewall will look up the ACK packet in its state-table and discard the segment because it does not correspond to any active connection. A TCP ACK Ping can be used to discover if a host is alive via RST response packets sent from the host.\n\n**Prerequisites.** - The ability to send an ACK packet to a remote host and identify the response. Creating the ACK packet without building a full connection requires the use of raw sockets. As a result, it is not possible to send a TCP ACK ping from some systems (Windows XP SP 2) without the use of third-party packet drivers like Winpcap. On other systems (BSD, Linux) administrative privileges are required in order to write to the raw socket.\n- The target must employ a stateless firewall that lacks a rule set that rejects unsolicited ACK packets.\n- The adversary requires the ability to craft custom TCP ACK segments for use during network reconnaissance. Sending an ACK ping requires the ability to access \"raw sockets\" in order to create the packets with direct access to the packet header.\n\n**Resources required.** ACK scanning can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language. Packet injection tools are also useful for this purpose.

If a UDP datagram is sent to an open UDP port there is very often no response, so a typical strategy for using a UDP ping is to send the datagram to a random high port on the target. The goal is to solicit an 'ICMP port unreachable' message from the target, indicating that the host is alive. UDP pings are useful because some firewalls are not configured to block UDP datagrams sent to strange or typically unused ports, like ports in the 65K range. Additionally, while some firewalls may filter incoming ICMP, weaknesses in firewall rule-sets may allow certain types of ICMP (host unreachable, port unreachable) which are useful for UDP ping attempts.\n\n**Prerequisites.** - The adversary requires the ability to send a UDP datagram to a remote host and receive a response.\n- The adversary requires the ability to craft custom UDP Packets for use during network reconnaissance.\n- The target's firewall must not be configured to block egress ICMP messages.\n\n**Resources required.** UDP pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language. Packet injection tools are also useful for this purpose. Depending upon the technique used it may also be necessary to sniff the network in order to see the response.\n\n**Mitigations.** - Configure your firewall to block egress ICMP messages.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Related patterns.** - ChildOf: CAPEC-292\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n\n## Reference: CAPEC-299 TCP SYN Ping\n**CAPEC-299 TCP SYN Ping (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary uses TCP SYN packets as a means towards host discovery. Typical RFC 793 behavior specifies that when a TCP port is open, a host must respond to an incoming SYN \"synchronize\" packet by completing stage two of the 'three-way handshake' - by sending an SYN/ACK in response. When a port is closed, RFC 793 behavior is to respond with a RST \"reset\" packet. This behavior can be used to 'ping' a target to see if it is alive by sending a TCP SYN packet to a port and then looking for a RST or an ACK packet in response.\n\n**Prerequisites.** - The ability to send a TCP SYN packet to a remote target. Depending upon the operating system, the ability to craft SYN packets may require elevated privileges.\n\n**Skills required.** - The adversary needs to know how to craft and send protocol commands from the command line or within a tool.\n\n**Resources required.** SYN pings can be performed via the use of a port scanner or by raw socket manipulation using a scripting or programming language.

An adversary can intentionally introduce leading \"ghost\" characters (extra characters that don't affect the validity of the request at the API layer) that enable the input to pass the filters and therefore process the adversary's input. This occurs when the targeted API will accept input data in several syntactic forms and interpret it in the equivalent semantic way, while the filter does not take into account the full spectrum of the syntactic forms acceptable to the targeted API.\n\n**Prerequisites.** - The targeted API must ignore the leading ghost characters that are used to get past the filters for the semantics to be the same.\n\n**Skills required.** - The ability to make an API request, and knowledge of \"ghost\" characters that will not be filtered by any input validation. These \"ghost\" characters must be known to not affect the way in which the request will be interpreted.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser, an automated tool or by inspecting the application, an adversary records all entry points to the application.\n. ****: [Probe entry points to locate vulnerabilities] The adversary uses the entry points gathered in the \"Explore\" phase as a target list and injects various leading 'Ghost' character sequences to determine how to application filters them.\n. ****: [Bypass input filtering] Using what the adversary learned about how the application filters input data, they craft specific input data that bypasses the filter. This can lead to directory traversal attacks, arbitrary shell command execution, corruption of files, etc.\n\n**Mitigations.** - Use an allowlist rather than a denylist input validation.\n- Canonicalize all data prior to validation.\n- Take an iterative approach to input validation (defense in depth).

The user would install this 3rd party app instead of the Facebook app.\n\n**Execution flow.** . ****: [Determine target web application] An adversary first needs to determine what web application they wish to target.\n. ****: [Create malicious application] An adversary creates an application, often mobile, that incorporates a WebView component to display the targeted web application. This malicious application needs to downloaded by a user, so adversaries will make this application useful in some way.\n. ****: [Get the victim to download and run the application] An adversary needs to get the victim to willingly download and run the application.\n. ****: [Inject malicious code] Once the victim runs the malicious application and views the targeted web page in the WebView component, the malicious application will inject malicious JavaScript code into the web application. This is done by using WebView's loadURL API, which can inject arbitrary JavaScript code into pages loaded by the WebView component with the same privileges. This is often done by adding a script tag to the document body with a src destination to a remote location that serves malicious JavaScript code.\n\n**Mitigations.** - The only known mitigation to this type of attack is to keep the malicious application off the system. There is nothing that can be done to the target application to protect itself from a malicious application that has been installed and executed.

The malicious activity is then used to mimic the trusted activity's user interface and prompt the target to enter sensitive data as if they were interacting with the trusted activity.\n\n**Prerequisites.** - The adversary must have previously installed the malicious application onto the Android device that will run in place of the trusted activity.\n\n**Skills required.** - The adversary must typically overcome network and host defenses in order to place malware on the system.\n\n**Resources required.** Malware capable of acting on the adversary's objectives.\n\n**Execution flow.** . ****: [Find an android application that uses implicit intents] Since this attack only works on android applications that use implicit intents, rather than explicit intents, an adversary must first identify an app that uses implicit intents to launch an Android-based trusted activity, and what that activity is.\n. ****: [Create a malicious app] The adversary must create a malicious android app meant to intercept implicit intents to launch an Adroid-based trusted activity. This malicious app will mimic the trusted activiy's user interface to get the user to enter sensitive data.\n. ****: [Get user to download malicious app] The adversary must get a user using the targeted app to download the malicious app by any means necessary\n. ****: [Gather sensitive data through malicious app] Once the target application sends an implicit intent to launch a trusted activity, the malicious app will be launched instead that looks identical to the interface of that activity. When the user enters sensitive information it will be captured by the malicious app.\n\n**Mitigations.** - To mitigate this type of an attack, explicit intents should be used whenever sensitive data is being sent. An 'explicit intent' is delivered to a specific application as declared within the intent, whereas an 'implicit intent' is directed to an application as defined by the Android operating system.

Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the Android device and convince the user to execute it. The malicious application will be used to issue spoofed intents.\n\n**Mitigations.** - To limit one's exposure to this type of attack, developers should avoid exporting components unless the component is specifically designed to handle requests from untrusted applications. Developers should be aware that declaring an intent filter will automatically export the component, exposing it to public access. Critical, state-changing actions should not be placed in exported components. If a single component handles both interand intra-application requests, the developer should consider dividing that component into separate components. If a component must be exported (e.g., to receive system broadcasts), then the component should dynamically check the caller's identity prior to performing any operations. Requiring Signature or SignatureOrSystem permissions is an effective way of limiting a component's exposure to a set of trusted applications. Finally, the return values of exported components can also leak private data, so developers should check the caller's identity prior to returning sensitive values.\n\n**Related patterns.** - ChildOf: CAPEC-148\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)\n\n## Reference: CAPEC-503 WebView Exposure\n**CAPEC-503 WebView Exposure (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.\n\n**Prerequisites.** - This type of an attack requires the adversary to convince the user to load the malicious web page inside the target application. Once loaded, the malicious web page will have the same permissions as the target application and will have access to all registered interfaces. Both the permission and the interface must be in place for the functionality to be exposed.\n\n**Mitigations.** - To mitigate this type of an attack, an application should limit permissions to only those required and should verify the origin of all web content it loads.\n\n**Related patterns.** - ChildOf: CAPEC-122\n\n**Underlying weaknesses.** - CWE-284 (Improper Access Control)\n\n## Reference: CAPEC-504 Task Impersonation\n**CAPEC-504 Task Impersonation (full record).** Abstraction: Standard; Status: Stable; Severity: High; Likelihood: Medium\nAn adversary, through a previously installed malicious application, impersonates an expected or routine task in an attempt to steal sensitive information or leverage a user's privileges.\n\n**Prerequisites.** - The adversary must already have access to the target system via some means.\n- A legitimate task must exist that an adversary can impersonate to glean credentials.\n- The user's privileges allow them to execute certain tasks with elevated privileges.\n\n**Skills required.** - Once an adversary has gained access to the target system, impersonating a task is trivial.\n\n**Resources required.** Malware or some other means to initially comprise the target system. Additional malware to impersonate a legitimate task.\n\n**Execution flow.** . ****: [Determine suitable tasks to exploit] Determine what tasks exist on the target system that may result in a user providing sensitive information.\n. ****: [Impersonate Task] Impersonate a legitimate task, either expected or unexpected, in an attempt to gain user credentials or to ride the user's privileges.\n\n**Mitigations.** - The only known mitigation to this attack is to avoid installing the malicious application on the device.

Fuzzing is a software security and functionality testing method that feeds randomly constructed input to the system and looks for an indication that a failure in response to that input has occurred. Fuzzing treats the system as a black box and is totally free from any preconceptions or assumptions about the system. Fuzzing can help an attacker discover certain assumptions made about user input in the system. Fuzzing gives an attacker a quick way of potentially uncovering some of these assumptions despite not necessarily knowing anything about the internals of the system. These assumptions can then be turned against the system by specially crafting user input that may allow an attacker to achieve their goals.\n\n**Skills required.** - There is a wide variety of fuzzing tools available.\n\n**Resources required.** Fuzzing tools.\n\n**Execution flow.** . ****: [Observe communication and inputs] The fuzzing attacker observes the target system looking for inputs and communications between modules, subsystems, or systems.\n. ****: [Generate fuzzed inputs] Given a fuzzing tool, a target input or protocol, and limits on time, complexity, and input variety, generate a list of inputs to try. Although fuzzing is random, it is not exhaustive. Parameters like length, composition, and how many variations to try are important to get the most cost-effective impact from the fuzzer.\n. ****: [Observe the outcome] Observe the outputs to the inputs fed into the system by fuzzers and see if anything interesting happens. If failure occurs, determine why that happened. Figure out the underlying assumption that was invalidated by the input.\n. ****: [Craft exploit payloads] Put specially crafted input into the system that leverages the weakness identified through fuzzing and allows to achieve the goals of the attacker. Fuzzers often reveal ways to slip through the input validation filters and introduce unwanted data into the system.

If the request is not blocked by a firewall or ACL, the target host will respond with an ICMP Type 0 Echo Reply datagram. This type of exchange is usually referred to as a 'Ping' due to the Ping utility present in almost all operating systems. Ping, as commonly implemented, allows a user to test for alive hosts, measure round-trip time, and measure the percentage of packet loss.\n\n**Prerequisites.** - The ability to send an ICMP type 8 query (Echo Request) to a remote target and receive an ICMP type 0 message (ICMP Echo Reply) in response. Any firewalls or access control lists between the sender and receiver must allow ICMP Type 8 and ICMP Type 0 messages in order for a ping operation to succeed.\n\n**Skills required.** - The adversary needs to know certain linux commands for this type of attack.\n\n**Resources required.** Scanners or utilities that provide the ability to send custom ICMP queries.\n\n**Mitigations.** - Consider configuring firewall rules to block ICMP Echo requests and prevent replies.

SYN scanning is the most common type of port scanning that is used because of its many advantages and few drawbacks. As a result, novice attackers tend to overly rely on the SYN scan while performing system reconnaissance. As a scanning method, the primary advantages of SYN scanning are its universality and speed.\n\n**Prerequisites.** - This scan type is not possible with some operating systems (Windows XP SP 2). On Linux and Unix systems it requires root privileges to use raw sockets.\n\n**Resources required.** The ability to send TCP SYN segments to a host during network reconnaissance via the use of a network mapper or scanner, or via raw socket programming in a scripting language. Packet injection tools are also useful for this purpose. Depending upon the method used it may be necessary to sniff the network in order to see the response.\n\n**Execution flow.** . ****: An adversary sends SYN packets to ports they want to scan and checks the response without completing the TCP handshake.\n. ****: An adversary uses the response from the target to determine the port's state. The adversary can determine the state of a port based on the following responses. When a SYN is sent to an open port and unfiltered port, a SYN/ACK will be generated. When a SYN packet is sent to a closed port a RST is generated, indicating the port is closed. When SYN scanning to a particular port generates no response, or when the request triggers ICMP Type 3 unreachable errors, the port is filtered.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Related patterns.** - ChildOf: CAPEC-300\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)"}]}

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.\n\n## Classification\n- Abstraction: Detailed\n- Status: Draft\n- Typical severity: High\n- Likelihood of attack: High\n\n## Mapped weaknesses (CWE)\nCWE-177, CWE-173, CWE-172, CWE-73, CWE-22, CWE-74, CWE-20, CWE-697, CWE-707\n\n## Examples in the field\n- **Example instance**: Attack Example: Combined Encodings CesarFTP Alexandre Cesari released a freeware FTP server for Windows that fails to provide proper filtering against multiple encoding. The FTP server, CesarFTP, included a Web server component that could be attacked with a combination of the triple-dot and URL encoding attacks. An attacker could provide a URL that included a string like This is an interesting exploit because it involves an aggregation of several tricks: the escape character, URL encoding, and the triple dot.\n\n## Why examples help\nConcrete instances turn an abstract pattern into something you can reconnoitre for and recognise, and they reveal the prerequisites actually used in the wild.\n\n## Execution flow\n. ****: The attacker accesses the server using a specific URL.\n. ****: The attacker tries to encode some special characters in the URL. The attacker find out that some characters are not filtered properly.\n. ****: The attacker crafts a malicious URL string request and sends it to the server.\n. ****: The server decodes and interprets the URL string. Unfortunately since the input filtering is not done properly, the special characters have harmful consequences.\n\n## Underlying weaknesses\n- CWE-177 (Improper Handling of URL Encoding (Hex Encoding))\n- CWE-173 (Improper Handling of Alternate Encoding)\n- CWE-172 (Encoding Error)\n- CWE-73 (External Control of File Name or Path)\n- CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'))\n- CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'))\n- CWE-20 (Improper Input Validation)\n- CWE-697 (Incorrect Comparison)\n- CWE-707 (Improper Neutralization)\n\n## Reference: CAPEC-236 DEPRECATED: Catching exception throw/signal from privileged block\n**CAPEC-236 DEPRECATED: Catching exception throw/signal from privileged block (full record).** Abstraction: Detailed; Status: Deprecated; Severity: n/a; Likelihood: n/a\nThis attack pattern has been deprecated as it did not have enough distinction from CAPEC-30: Hijacking a Privileged Thread of Execution.

For instance, Java code cannot perform unsafe operations, such as modifying arbitrary memory locations, due to restrictions placed on it by the Byte code Verifier and the JVM. If allowed, Java code can call directly into native C code, which may perform unsafe operations, such as call system calls and modify arbitrary memory locations on their behalf. To provide isolation, Java does not grant untrusted code with unmediated access to native C code. Instead, the sandboxed code is typically allowed to call some subset of the pre-existing native code that is part of standard libraries.\n\n**Skills required.** - The attacker must have a good knowledge of the platform specific mechanisms of signing and verifying code. Most code signing and verification schemes are based on use of cryptography, the attacker needs to have an understand of these cryptographic operations in good detail.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Probing] The attacker probes the target application to see whether calling code of another language is allowed within a sandbox.\n. ****: [Analysis] The attacker analyzes the target application to get a list of cross code weaknesses in the standard libraries of the sandbox.\n. ****: [Verify the exploitable security weaknesses] The attacker tries to craft malicious code of another language allowed by the sandbox to verify the security weaknesses of the standard libraries found in the Explore phase.\n. ****: [Exploit the security weaknesses in the standard libraries] The attacker calls malicious code of another language to exploit the security weaknesses in the standard libraries verified in the Experiment phase.

An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).\n\n**Prerequisites.** - Ability to control the length of data passed to an active filter.\n\n**Skills required.** - An attacker can simply overflow a buffer by inserting a long string into an attacker-modifiable injection vector.

This can be done manually or a dynamic tool (black box) can be used to automate this. An attacker can also use a custom script for that purpose.\n. ****: [Monitor responses] Watch for any indication of failure occurring. Carefully watch to see what happened when filter failure occurred. Did the data get in?\n. ****: [Abuse the system through filter failure] An attacker writes a script to consistently induce the filter failure.\n\n**Mitigations.** - Make sure that ANY failure occurring in the filtering or input validation routine is properly handled and that offending input is NOT allowed to go through. Basically make sure that the vault is closed when failure occurs.\n- Pre-design: Use a language or compiler that performs automatic bounds checking.\n- Pre-design through Build: Compiler-based canary mechanisms such as StackGuard, ProPolice and the Microsoft Visual Studio /GS flag. Unless this provides automatic bounds checking, it is not a complete solution.\n- Operational: Use OS-level preventative functionality.

Many filters do not adequately sanitize attributes against the presence of potentially dangerous commands even if they adequately sanitize tags. For example, dangerous expressions could be inserted into a style attribute in an anchor tag, resulting in the execution of malicious code when the resulting page is rendered. If a victim is tricked into viewing the rendered page the attack proceeds like a normal XSS attack, possibly resulting in the loss of sensitive cookies or other malicious activities.\n\n**Prerequisites.** - The target application must fail to adequately sanitize HTML attributes against the presence of dangerous commands.\n\n**Resources required.** The adversary must trick the victim into following a crafted link to a vulnerable server or view a web post where the dangerous commands are executed.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser or an automated tool, an adversary follows all public links and actions on a web site. They record all the links, the forms, the resources accessed and all other potential entry-points for the web application.\n. ****: [Probe identified potential entry points for XSS targeting HTML attributes] The adversary uses the entry points gathered in the \"Explore\" phase as a target list and injects various malicious expressions as input, hoping to embed them as HTML attributes.\n. ****: [Craft malicious XSS URL] Once the adversary has determined which parameters are vulnerable to XSS, they will craft a malicious URL containing the XSS exploit. The adversary can have many goals, from stealing session IDs, cookies, credentials, and page content from the victim.\n. ****: [Get victim to click URL] In order for the attack to be successful, the victim needs to access the malicious URL.\n\n**Mitigations.** - Design: Use libraries and templates that minimize unfiltered input.\n- Implementation: Normalize, filter and use an allowlist for all input including that which is not expected to have any scripting content.\n- Implementation: The victim should configure the browser to minimize active content from untrusted sources.

An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received.

The attacker could manipulate the system if the attacker-created file is trusted by the operating system or an application component that attempts to load the original file. Applications often load or include external files, such as libraries or configuration files. These files should be protected against malicious manipulation. However, if the application only uses the name of the file when locating it, an attacker may be able to create a file with the same name and place it in a directory that the application will search before the directory with the legitimate file is searched.

ATA Security is often employed to protect hard disk information from unauthorized access. The mechanism requires the user to type in a password before the BIOS is allowed access to drive contents. Some implementations of ATA security will accept the ATA command to update the password without the user having authenticated with the BIOS. This occurs because the security mechanism assumes the user has first authenticated via the BIOS prior to sending commands to the drive. Various methods exist for exploiting this flaw, the most common being installing the ATA protected drive into a system lacking ATA security features (a.k.a. hot swapping). Once the drive is installed into the new system the BIOS can be used to reset the drive password.\n\n**Prerequisites.** - Access to the system containing the ATA Drive so that the drive can be physically removed from the system.\n\n**Mitigations.** - Avoid using ATA password security when possible.\n- Use full disk encryption to protect the entire contents of the drive or sensitive partitions on the drive.\n- Leverage third-party utilities that interface with self-encrypting drives (SEDs) to provide authentication, while relying on the SED itself for data encryption.\n\n**Example instances.** - The A-FF Repair Station tool is a data recovery utility that can be used for ATA password removal (both High and Maximum level) and firmware area recovery.

This is often accomplished by overlaying one screen on top of another while giving the appearance of a single interface. There are two main techniques used to accomplish this. The first is to leverage transparent properties that allow taps on the screen to pass through the visible application to an application running in the background. The second is to strategically place a small object (e.g., a button or text field) on top of the visible screen and make it appear to be a part of the underlying application. In both cases, the user is convinced to tap on the screen but does not realize the application that they are interacting with.\n\n**Prerequisites.** - This pattern of attack requires the ability to execute a malicious application on the user's device.

As Attackers use this attack process to classify, map, and identify vulnerable aspects of an application, it simply requires hypotheses to be verified, interaction with the application, and time to conduct trial-and-error activities.\n\n**Skills required.** - Although fuzzing parameters is not difficult, and often possible with automated fuzzers, interpreting the error conditions and modifying the parameters so as to move further in the process of mapping the application requires detailed knowledge of target platform, the languages and packages used as well as software design.\n\n**Resources required.** The Attacker needs the ability to probe application functionality and provide it erroneous directives or data without triggering intrusion detection schemes or making enough of an impact on application logging that steps are taken against the adversary. The Attack does not need special hardware, software, skills, or access.\n\n**Execution flow.** . ****: [Determine parameters] Determine all user-controllable parameters of the application either by probing or by finding documentation\n. ****: [Cause error condition] Inject each parameter with content that causes an error condition to manifest\n. ****: [Modify parameters] Modify the content of each parameter according to observed error conditions\n. ****: [Follow up attack] Once the above steps have been repeated with enough parameters, the application will be sufficiently mapped out. The adversary can then launch a desired attack (for example, Blind SQL Injection)\n\n**Mitigations.** - Application designers can construct a 'code book' for error messages. […]"}]}

Email software has become increasingly sophisticated and feature-rich. In addition, email applications are ubiquitous and connected directly to the Web making them ideal targets to launch and propagate attacks. As the user demand for new functionality in email applications grows, they become more like browsers with complex rendering and plug in routines. As more email functionality is included and abstracted from the user, this creates opportunities for attackers. Virtually all email applications do not list email header information by default, however the email header contains valuable attacker vectors for the attacker to exploit particularly if the behavior of the email client application is known. Meta-characters are hidden from the user, but can contain scripts, enumerations, probes, and other attacks against the user's system.\n\n**Prerequisites.** - This attack targets most widely deployed feature rich email applications, including web based email programs.\n\n**Skills required.** - To distribute email\n\n**Execution flow.** . ****: [Identify and characterize metacharacter-processing vulnerabilities in email headers] An attacker creates emails with headers containing various metacharacter-based malicious payloads in order to determine whether the target application processes the malicious content and in what manner it does so.\n. ****: An attacker leverages vulnerabilities identified during the Experiment Phase to inject malicious email headers and cause the targeted email application to exhibit behavior outside of its expected constraints.\n\n**Mitigations.** - Design: Perform validation on email header data\n- Implementation: Implement email filtering solutions on mail server or on MTA, relay server.\n- Implementation: Mail servers that perform strict validation may catch these attacks, because metacharacters are not allowed in many header variables such as dns names\n\n**Consequences.** - None (None)\n\n**Example instances.** - Meta-characters are among the most valuable tools attackers have to deceive users into taking some action on their behalf.

Accurate contextual and environmental queues, such as knowing important information about the target company or individual can greatly increase the success of the attack and the quality of information gathered. Authentic mimicry combined with detailed knowledge increases the success of elicitation attacks.\n\n## Reference: CAPEC-411 DEPRECATED: Pretexting\n**CAPEC-411 DEPRECATED: Pretexting (full record).** Abstraction: Meta; Status: Deprecated; Severity: n/a; Likelihood: n/a\nThis attack pattern has been deprecated as it is a duplicate of the existing attack pattern \"CAPEC-407: Social Information Gathering via Pretexting\".

An adversary who uses social engineering to impersonate a tech support worker can have devastating effects on a network. This is an effective attack vector, because it can give an adversary physical access to network computers. It only takes a matter of seconds for someone to compromise a computer with physical access. One of the best technological tools at the disposal of a social engineer, posing as a technical support person, is a USB thumb drive. These are small, easy to conceal, and can be loaded with different payloads depending on what task needs to be done. However, this form of attack does not require physical access as it can also be effectively carried out via phone or email.\n\n**Related patterns.** - ChildOf: CAPEC-407\n\n## Reference: CAPEC-414 Pretexting via Delivery Person\n**CAPEC-414 Pretexting via Delivery Person (full record).** Abstraction: Detailed; Status: Draft; Severity: Low; Likelihood: n/a\nAn adversary engages in pretexting behavior, assuming the role of a delivery person, to solicit information from target persons, or manipulate the target into performing an action that serves the adversary's interests. Impersonating a delivery person is an effective attack and an easy attack since not much acting is involved. Usually the hardest part is looking the part and having all of the proper credentials, papers and \"deliveries\" in order to be able to pull it off.\n\n**Related patterns.** - ChildOf: CAPEC-407\n\n## Reference: CAPEC-415 Pretexting via Phone\n**CAPEC-415 Pretexting via Phone (full record).** Abstraction: Detailed; Status: Draft; Severity: Low; Likelihood: n/a\nAn adversary engages in pretexting behavior, assuming some sort of trusted role, and contacting the targeted individual or organization via phone to solicit information from target persons, or manipulate the target into performing an action that serves the adversary's interests. This is the most common social engineering attack. Some of the most commonly effective approaches are to impersonate a fellow employee, impersonate a computer technician or to target help desk personnel.\n\n**Related patterns.** - ChildOf: CAPEC-407\n\n## Reference: CAPEC-416 Manipulate Human Behavior\n**CAPEC-416 Manipulate Human Behavior (full record).** Abstraction: Meta; Status: Stable; Severity: Medium; Likelihood: Medium\nAn adversary exploits inherent human psychological predisposition to influence a targeted individual or group to solicit information or manipulate the target into performing an action that serves the adversary's interests. Many interpersonal social engineering techniques do not involve outright deception, although they can; many are subtle ways of manipulating a target to remove barriers, make the target feel comfortable, and produce an exchange in which the target is either more likely to share information directly, or let key information slip out unintentionally. A skilled adversary uses these techniques when appropriate to produce the desired outcome. Manipulation techniques vary from the overt, such as pretending to be a supervisor to a help desk, to the subtle, such as making the target feel comfortable with the adversary's speech and thought patterns.\n\n**Prerequisites.** - The adversary must have the means and knowledge of how to communicate with the target in some manner.\n\n**Mitigations.** - An organization should provide regular, robust cybersecurity training to its employees to prevent successful social engineering attacks.\n\n**Consequences.** - None (None)\n\n## Reference: CAPEC-417 Influence Perception\n**CAPEC-417 Influence Perception (full record).** Abstraction: Standard; Status: Stable; Severity: Low; Likelihood: High\nThe adversary uses social engineering to exploit the target's perception of the relationship between the adversary and themselves. This goal is to persuade the target to unknowingly perform an action or divulge information that is advantageous to the adversary.\n\n**Prerequisites.** - The adversary must have the means and knowledge of how to communicate with the target in some manner.\n\n**Skills required.** - The adversary requires strong inter-personal and communication skills.\n\n**Resources required.** There are no necessary resources required for this attack.\n\n**Mitigations.** - An organization should provide regular, robust cybersecurity training to its employees to prevent social engineering attacks."}]}
