There are an almost limitless number of ways an attacker can modify a technology when they are involved in its manufacture, as the attacker has potential inroads to the software composition, hardware design and assembly, firmware, or basic design mechanics. Additionally, manufacturing of key components is often outsourced with the final product assembled by the primary manufacturer. The greatest risk, however, is deliberate manipulation of design specifications to produce malicious hardware or devices.

Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the adversary access to the execution stack and execute arbitrary code in the target process.\n\n**Prerequisites.** - Target software processes binary resource files.\n- Target software contains a buffer overflow vulnerability reachable through input from a user-controllable binary resource file.\n\n**Skills required.** - To modify file, deceive client into downloading, locate and exploit remote stack or heap vulnerability\n\n**Execution flow.** . ****: [Identify target software] The adversary identifies software that uses external binary files in some way. This could be a file upload, downloading a file from a shared location, or other means.\n. ****: [Find injection vector] The adversary creates a malicious binary file by altering the header to make the file seem shorter than it is. Additional bytes are added to the end of the file to be placed in the overflowed location. The adversary then deploys the file to the software to determine if a buffer overflow was successful.\n. ****: [Craft overflow content] Once the adversary has determined that this attack is viable, they will specially craft the binary file in a way that achieves the desired behavior.

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. This attack pattern is included in CAPEC for historical purposes.\n\n**Prerequisites.** - System must use weak authentication mechanisms for administrative functions.\n\n**Skills required.** - Given a vulnerable phone system, the attackers' technical vector relies on attacks that are well documented in cracker 'zines and have been around for decades.\n\n**Resources required.** CCITT-5 or other vulnerable lines, with the ability to send tones such as combined 2,400 Hz and 2,600 Hz tones to the switch\n\n**Mitigations.** - Implementation: Upgrade phone lines.

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. 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. […]\n\n## Reference: CAPEC-502 Intent Spoof\n**CAPEC-502 Intent Spoof (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary, through a previously installed malicious application, issues an intent directed toward a specific trusted application's component in an attempt to achieve a variety of different objectives including modification of data, information disclosure, and data injection. 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)"}]}

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.

Exploitation of this preferential search order can allow an attacker to make the loading process load the adversary's rogue library rather than the legitimate library.

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. Access can be redirected through a number of techniques, including the use of symbolic links, search path modification, and relative path manipulation.\n\n**Prerequisites.** - The target must utilize external libraries and must fail to verify the integrity of these libraries before using them.\n\n**Skills required.** - To modify the entries in the configuration file pointing to malicious libraries\n- To force symlink and timing issues for redirecting access to libraries\n- To reverse engineering the libraries and inject malicious code into the libraries\n\n**Execution flow.** . ****: [Identify Target] The adversary identifies the target application and determines what libraries are being used.\n. ****: [Deploy Malicious Libraries] The adversary crafts malicious libraries and deploys them on the system where the application is running, or in a remote location that can be loaded by the application.\n. ****: [Redirect Library Calls to Malicious Library] Once the malicious library crafted by the adversary is deployed, the adversary will manipulate the flow of the application such that it calls the malicious library.

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.

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 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 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.

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)"}]}

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.

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.

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.. 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. 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. These technologies share common weaknesses that an attacker can exploit to gain access to a facility protected by the mechanisms via copying legitimate cards or badges, or generating new cards using reverse-engineered algorithms."}]}

Then an attacker creates special payloads to bypass this filter: When the application gets this input string, it will be the desired vector by the attacker.\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## Definition\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. 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## Classification\n- Abstraction: Detailed\n- Status: Draft\n- Typical severity: High\n- Likelihood of attack: High\n\n## Mapped weaknesses (CWE)\nCWE-23\n\n## Reference: CAPEC-275 DNS Rebinding\n**CAPEC-275 DNS Rebinding (full record).** Abstraction: Detailed; Status: Draft; Severity: Very High; Likelihood: High\nAn adversary serves content whose IP address is resolved by a DNS server that the adversary controls. After initial contact by a web browser (or similar client), the adversary changes the IP address to which its name resolves, to an address within the target organization that is not publicly accessible. This allows the web browser to examine this internal address on behalf of the adversary.\n\n**Prerequisites.** - The target browser must access content server from the adversary controlled DNS name. Web advertisements are often used for this purpose. The target browser must honor the TTL value returned by the adversary and re-resolve the adversary's DNS name after initial contact.\n\n**Skills required.** - Setup DNS server and the adversary's web server. Write a malicious script to allow the victim to connect to the web server.\n\n**Resources required.** The adversary must serve some web content that a victim accesses initially. This content must include executable content that queries the adversary's DNS name (to provide the second DNS resolution) and then performs the follow-on attack against the internal system. The adversary also requires a customized DNS server that serves an IP address for their registered DNS name, but which resolves subsequent requests by a single client to addresses internal to that client's network.\n\n**Execution flow.** . ****: [Identify potential DNS rebinding targets] An adversary publishes content on their own server with their own name and DNS server. Attract HTTP traffic and explore rebinding vulnerabilities in browsers, flash players of old version.\n. ****: [Establish initial target access to adversary DNS] The first time the target accesses the adversary's content, the adversary's name must be resolved to an IP address. The adversary's DNS server performs this resolution, providing a short Time-To-Live (TTL) in order to prevent the target from caching the value.\n.

By leveraging this pattern of attack, the adversary is able to gain access to data or resources normally restricted, or to cause the application or service to crash.\n\n**Prerequisites.** - The targeted application or service must rely on web service protocols in such a way that malicious manipulation of them can alter functionality.\n\n**Resources required.** The attacker must be able to manipulate the communications to the targeted application or service.\n\n**Mitigations.** - Design: Range, size and value and consistency verification for any arguments supplied to applications and services from external sources and devise appropriate error response.\n- Design: Ensure that function calls that should not be called by an unprivileged user are not accessible to them.\n\n**Related patterns.** - ChildOf: CAPEC-272\n\n**Underlying weaknesses.** - CWE-707 (Improper Neutralization)\n\n## Reference: CAPEC-279 SOAP Manipulation\n**CAPEC-279 SOAP Manipulation (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: Medium\nSimple Object Access Protocol (SOAP) is used as a communication protocol between a client and server to invoke web services on the server. It is an XML-based protocol, and therefore suffers from many of the same shortcomings as other XML-based protocols. Adversaries can make use of these shortcomings and manipulate the content of SOAP paramters, leading to undesirable behavior on the server and allowing the adversary to carry out a number of further attacks.\n\n**Prerequisites.** - An application uses SOAP-based web service api.\n- An application does not perform sufficient input validation to ensure that user-controllable data is safe for an XML parser.\n- The targeted server either fails to verify that data in SOAP messages conforms to the appropriate XML schema, or it fails to correctly handle the complete range of data allowed by the schema.\n\n**Execution flow.** . ****: [Find target application] The adversary needs to identify an application that uses SOAP as a communication protocol.\n. ****: [Detect Incorrect SOAP Parameter Handling] The adversary tampers with the SOAP message parameters and looks for indications that the tampering caused a change in behavior of the targeted application.\n. ****: [Manipulate SOAP parameters] The adversary manipulates SOAP parameters in a way that causes undesirable behavior for the server.

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.

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.

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.

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.

This attack is executed after a trusted user is authenticated into a cloud service, \"piggy-backing\" on the authenticated session, and exploiting the fact that the cloud service believes it is only interacting with the trusted user. If successful, the actions embedded in the malicious application will be processed and accepted by the targeted SaaS application and executed at the trusted user's privilege level.\n\n**Prerequisites.** - An adversary must be able install a purpose built malicious application onto the trusted user's system and convince the user to execute it while authenticated to the SaaS application.\n\n**Skills required.** - This attack pattern often requires the technical ability to modify a malicious software package (e.g. Zeus) to spider a targeted site and a way to trick a user into a malicious software download.\n\n**Mitigations.** - To limit one's exposure to this type of attack, tunnel communications through a secure proxy service.\n- Detection of this type of attack can be done through heuristic analysis of behavioral anomalies (a la credit card fraud detection) which can be used to identify inhuman behavioral patterns.

The attack then uses this access to exfiltrate sensitive data or information, manipulate said data or information, and conceal these actions. This will allow and aid the attack to meet the goal of future compromise of a recipient of the victim's manufactured product further down in the supply chain.\n\n**Prerequisites.** - The victim must use email or removable media from systems running the IDE (or systems adjacent to the IDE systems).\n- The victim must have a system running exploitable applications and/or a vulnerable configuration to allow for initial infiltration.\n- The attacker must have working knowledge of some if not all of the components involved in the IDE system as well as the infrastructure.\n\n**Skills required.** - Intelligence about the manufacturer's operating environment and infrastructure.\n- Ability to develop, deploy, and maintain a stealth malicious backdoor program remotely in what is essentially a hostile environment.\n- Development skills to construct malicious attachments that can be used to exploit vulnerabilities in typical desktop applications or system configurations.

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.

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## Underlying weaknesses\n- CWE-923 (Improper Restriction of Communication Channel to Intended Endpoints)\n\n## Reference: CAPEC-487 ICMP Flood\n**CAPEC-487 ICMP Flood (full record).** Abstraction: Standard; Status: Draft; Severity: n/a; Likelihood: n/a\nAn adversary may execute a flooding attack using the ICMP protocol with the intent to deny legitimate users access to a service by consuming the available network bandwidth. A typical attack involves a victim server receiving ICMP packets at a high rate from a wide range of source addresses. Additionally, due to the session-less nature of the ICMP protocol, the source of a packet is easily spoofed making it difficult to find the source of the attack.\n\n**Prerequisites.** - This type of an attack requires the ability to generate a large amount of ICMP traffic to send to the target server.\n\n**Mitigations.** - To mitigate this type of an attack, an organization can enable ingress filtering.

These attacks use legitimate session-based HTTP GET requests designed to consume large amounts of a server's resources. 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. Third party providers have dedicated resources and expertise that could allow them to update rules and prevent HTTP Floods very quickly.\n- Design: Use a load balancer such as nginx to prevent small scale HTTP Floods by dispersing traffic between a group of servers.\n- Implementation: Make a requesting machine solve some kind of challenge before allowing them to send an HTTP request.

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)"}]}

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.

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.

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)"}]}

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.

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.

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 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.

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\".

This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.\n\n**Prerequisites.** - The target must transmit data over a medium that is accessible to the adversary.\n\n**Resources required.** The adversary must have the necessary technology to intercept information passing between the nodes of a network. For TCP/IP, the capability to run tcpdump, ethereal, etc. can be useful. Depending upon the data being targeted the technological requirements will change.\n\n**Mitigations.** - Leverage encryption to encode the transmission of data thus making it accessible only to authorized parties.\n\n**Consequences.** - None (None)\n\n**Underlying weaknesses.** - CWE-319 (Cleartext Transmission of Sensitive Information)\n\n## Reference: CAPEC-12 Choosing Message Identifier\n**CAPEC-12 Choosing Message Identifier (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: High\nThis pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.\n\n**Prerequisites.** - Information and client-sensitive (and client-specific) data must be present through a distribution channel available to all users.\n- Distribution means must code (through channel, message identifiers, or convention) message destination in a manner visible within the distribution means itself (such as a control channel) or in the messages themselves.\n\n**Skills required.** - All the adversary needs to discover is the format of the messages on the channel/distribution means and the particular identifier used within the messages.\n\n**Resources required.** The adversary needs the ability to control source code or application configuration responsible for selecting which message/channel id is absorbed from the public distribution means.\n\n**Execution flow.** . ****: [Determine Nature of Messages] Determine the nature of messages being transported as well as the identifiers to be used as part of the attack\n. ****: [Authenticate] If required, authenticate to the distribution channel\n. ****: [Identify Known Client Identifiers] If any particular client's information is available through a control channel available to all users, the adversary will discover particular identifiers for targeted clients by observing this channel, or requesting client information through this channel.\n. ****: [Change Message Identifier] Adversaries with client access connecting to output channels could change their channel identifier and see someone else's (perhaps more privileged) data.\n\n**Mitigations.** - Associate some ACL (in the form of a token) with an authenticated user which they provide middleware.

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## Classification\n- Abstraction: Standard\n- Status: Draft\n- Typical severity: Medium\n- Likelihood of attack: Medium\n\n## Mapped weaknesses (CWE)\nCWE-384, CWE-664\n\n## Examples in the field\n- **Example instance**: This example uses client side scripting to set session ID in the victim's browser. The JavaScript code fixates a falsified session credential into victim's browser, with the help of crafted a URL link. A similar example uses session ID as an argument of the URL. Once the victim clicks the links, the attacker may be able to bypass authentication or piggy-back off some other authenticated victim's session.\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. ****: [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\n- 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.\n- Implementation: Regenerate and destroy session identifiers when there is a change in the level of privilege: This ensures that even though a potential victim may have followed a link with a fixated identifier, a new one is issued when the level of privilege changes.\n\n## Consequences\n- None (None)\n- None (None)\n- None (None)\n- None (None)\n- None (None)\n\n## Example instances\n- This example uses client side scripting to set session ID in the victim's browser.

The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash.\n\n**Prerequisites.** - The target application must fail to sanitize incoming messages adequately before processing.\n\n**Skills required.** - Although fuzzing parameters is not difficult, and often possible with automated fuzzing tools, 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.** Fuzzing tools, which automatically generate and send message variants, are necessary for this attack. The attacker must have sufficient access to send messages to the target. The attacker must also have the ability to observe the target application's log and/or error messages in order to collect information about the target.\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 might provide information to map the application\n.

Tools exist to automate part of the tasks, but to successfully use these tools in an attack scenario requires detailed understanding of the underlying principles.\n\n**Resources required.** The adversary needs the ability to sniff traffic, and optionally be able to route said traffic to a system where the sniffing of traffic can take place, and act upon the recovered traffic in real time.\n\n**Execution flow.** . ****: [Determine SSL/TLS Configuration] Determine the SSL/TLS configuration of either the server or client being targeted, preferably both. This is not a hard requirement, as the adversary can simply assume commonly exploitable configuration settings and indiscriminately attempt them.\n. ****: [Intercept Communication] Provide controlled access to the server by the client, by either providing a link for the client to click on, or by positioning one's self at a place on the network to intercept and control the flow of data between client and server, e.g. AiTM (adversary in the middle - CAPEC-94).\n. ****: [Capture or Manipulate Sensitive Data] Once the adversary has the ability to intercept the secure communication, they exploit the incorrectly configured SSL to view the encrypted communication. The adversary can choose to just record the secure communication or manipulate the data to achieve a desired effect.\n\n**Mitigations.** - Do not use SSL, as all SSL versions have been broken and should not be used.

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.

This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content.

If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.\n\n**Prerequisites.** - Information and client-sensitive (and client-specific) data must be present through a distribution channel available to all users.\n- Distribution means must code (through channel, message identifiers, or convention) message destination in a manner visible within the distribution means itself (such as a control channel) or in the messages themselves.\n\n**Skills required.** - All the adversary needs to discover is the format of the messages on the channel/distribution means and the particular identifier used within the messages.\n\n**Resources required.** The adversary needs the ability to control source code or application configuration responsible for selecting which message/channel id is absorbed from the public distribution means.\n\n**Execution flow.** . ****: [Determine Nature of Messages] Determine the nature of messages being transported as well as the identifiers to be used as part of the attack\n. ****: [Authenticate] If required, authenticate to the distribution channel\n. ****: [Identify Known Client Identifiers] If any particular client's information is available through a control channel available to all users, the adversary will discover particular identifiers for targeted clients by observing this channel, or requesting client information through this channel.\n. ****: [Change Message Identifier] Adversaries with client access connecting to output channels could change their channel identifier and see someone else's (perhaps more privileged) data.\n\n**Mitigations.** - Associate some ACL (in the form of a token) with an authenticated user which they provide middleware.

This may allow the adversary to bypass filters that attempt to detect illegal characters or strings, such as those that might be used in traversal or injection attacks. Filters may be able to catch illegal encoded strings, but may not catch doubly encoded strings. For example, a dot (.), often used in path traversal attacks and therefore often blocked by filters, could be URL encoded as %2E. However, many filters recognize this encoding and would still block the request. In a double encoding, the % in the above URL encoding would be encoded again as %25, resulting in %252E which some filters might not catch, but which could still be interpreted as a dot (.) by interpreters on the target.\n\n**Prerequisites.** - The target's filters must fail to detect that a character has been doubly encoded but its interpreting engine must still be able to convert a doubly encoded character to an un-encoded character.\n- The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Resources required.** Tools that automate encoding of data can assist the adversary in generating encoded strings.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser, an automated tool or by inspecting the application, an attacker records all entry points to the application.\n. ****: [Probe entry points to locate vulnerabilities] Try double-encoding for parts of the input in order to try to get past the filters.

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.

The adversary must be able to observe, read, and/or hear the communication traffic, but not necessarily block the communication or change its content. 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. Depending on the medium of transmission and the path the data takes between the sender and recipient, the adversary may require special equipment and/or require that this equipment be placed in specific locations (e.g., a network sniffing tool)\n\n**Execution flow.** . ****: [Determine Communication Mechanism] The adversary determines the nature and mechanism of communication between two components, looking for opportunities to exploit.\n. ****: [Position In Between Targets] The adversary positions themselves somewhere in the middle of the two components.

Network sniffing applications can reveal TCP/IP, DNS, Ethernet, and other low-level network communication information. The adversary takes a passive role in this attack pattern and simply observes and analyzes the traffic.

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. Access can be redirected through a number of techniques, including the use of symbolic links, search path modification, and relative path manipulation.\n\n**Prerequisites.** - The target must utilize external libraries and must fail to verify the integrity of these libraries before using them.\n\n**Skills required.** - To modify the entries in the configuration file pointing to malicious libraries\n- To force symlink and timing issues for redirecting access to libraries\n- To reverse engineering the libraries and inject malicious code into the libraries\n\n**Execution flow.** . ****: [Identify Target] The adversary identifies the target application and determines what libraries are being used.\n. ****: [Deploy Malicious Libraries] The adversary crafts malicious libraries and deploys them on the system where the application is running, or in a remote location that can be loaded by the application.\n. ****: [Redirect Library Calls to Malicious Library] Once the malicious library crafted by the adversary is deployed, the adversary will manipulate the flow of the application such that it calls the malicious library.

Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.\n\n**Prerequisites.** - The target must apply access controls, but incorrectly configure them. However, not all incorrect configurations can be exploited by an attacker. If the incorrect configuration applies too little security to some functionality, then the attacker may be able to exploit it if the access control would be the only thing preventing an attacker's access and it no longer does so. If the incorrect configuration applies too much security, it must prevent legitimate activity and the attacker must be able to force others to require this activity..\n\n**Skills required.** - In order to discover unrestricted resources, the attacker does not need special tools or skills. They only have to observe the resources or access mechanisms invoked as each action is performed and then try and access those access mechanisms directly.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Execution flow.** . ****: [Survey] The attacker surveys the target application, possibly as a valid and authenticated user.\n. ****: [Identify weak points in access control configurations] The attacker probes the access control for functions and data identified in the Explore phase to identify potential weaknesses in how the access controls are configured.\n. ****: [Access the function or data bypassing the access control] The attacker executes the function or accesses the data identified in the Explore phase bypassing the access control.\n\n**Mitigations.** - Design: Configure the access control correctly.\n\n**Consequences.** - None (None)\n- None (None)\n- None (None)\n- None (None)\n- None (None)\n- None (None)\n\n## Reference: CAPEC-181 Flash File Overlay\n**CAPEC-181 Flash File Overlay (full record).** Abstraction: Detailed; Status: Draft; Severity: Medium; Likelihood: n/a\nAn attacker creates a transparent overlay using flash in order to intercept user actions for the purpose of performing a clickjacking attack. In this technique, the Flash file provides a transparent overlay over HTML content. Because the Flash application is on top of the content, user actions, such as clicks, are caught by the Flash application rather than the underlying HTML. The action is then interpreted by the overlay to perform the actions the attacker wishes.\n\n**Prerequisites.** - The victim must be tricked into navigating to the attackers' decoy site and performing the actions on the decoy page.\n- The victim's browser must support invisible Flash overlays.\n\n**Resources required.** The attacker must be able to force the Flash overlay over the decoy content.\n\n**Related patterns.** - ChildOf: CAPEC-103\n\n**Underlying weaknesses.** - CWE-1021 (Improper Restriction of Rendered UI Layers or Frames)\n\n## Reference: CAPEC-182 Flash Injection\n**CAPEC-182 Flash Injection (full record).** Abstraction: Standard; Status: Draft; Severity: Medium; Likelihood: High\nAn attacker tricks a victim to execute malicious flash content that executes commands or makes flash calls specified by the 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. However, in most cases, the attacker will need to be a recognized user of the web-mail server.\n\n**Execution flow.** . ****: [Identify Target Web-Mail Server] The adversary first identifies the web-mail server they wish to exploit.\n. ****: [Identify Vulnerable Parameters] Once the adversary has identified a web-mail server, they identify any vulnerable parameters by altering their values in requests. The adversary knows that the parameter is vulnerable if the web-mail server returns an error of any sort. Ideally, the adversary is looking for a descriptive error message.\n. […]"}]}

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.

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 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.

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.

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.

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.

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.

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.

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. This attack pattern is included in CAPEC for historical purposes.\n\n**Prerequisites.** - System must use weak authentication mechanisms for administrative functions.\n\n**Skills required.** - Given a vulnerable phone system, the attackers' technical vector relies on attacks that are well documented in cracker 'zines and have been around for decades.\n\n**Resources required.** CCITT-5 or other vulnerable lines, with the ability to send tones such as combined 2,400 Hz and 2,600 Hz tones to the switch\n\n**Mitigations.** - Implementation: Upgrade phone lines.

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 that might load in certain files to memory.\n. ****: [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer.\n. ****: [Craft overflow file 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 specially crafted file content, the adversary creates a symbolic link from the identified resource to the malicious file, causing a targeted buffer overflow attack.\n\n**Mitigations.** - Pay attention to the fact that the resource you read from can be a replaced by a Symbolic link.

This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. 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.

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.

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.. 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. Most common locks, such as domestic locks in the US, can be picked using a standard 2 tools (i.e. a torsion wrench and a hook pick).\n\n**Related patterns.** - ChildOf: CAPEC-391\n\n## Reference: CAPEC-394 Using a Snap Gun Lock to Force a Lock\n**CAPEC-394 Using a Snap Gun Lock to Force a Lock (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker uses a Snap Gun, also known as a Pick Gun, to force the lock on a building or facility. 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. These technologies share common weaknesses that an attacker can exploit to gain access to a facility protected by the mechanisms via copying legitimate cards or badges, or generating new cards using reverse-engineered algorithms.\n\n**Related patterns.** - ChildOf: CAPEC-390\n\n## Reference: CAPEC-396 DEPRECATED: Bypassing Card or Badge-Based Systems\n**CAPEC-396 DEPRECATED: Bypassing Card or Badge-Based Systems (full record).** Abstraction: Standard; Status: Deprecated; Severity: n/a; Likelihood: n/a\nThis attack pattern has been deprecated as it a generalization of CAPEC-397: Cloning Magnetic Strip Cards, CAPEC-398: Magnetic Strip Card Brute Force Attacks, CAPEC-399: Cloning RFID Cards or Chips and CAPEC-400: RFID Chip Deactivation or Destruction.

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.\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. Some cards are protected by a checksum calculation, therefore it is necessary to determine what algorithm is being used to calculate the checksum and to employ that algorithm to calculate and write a new valid checksum for the card being created.\n\n**Related patterns.** - ChildOf: CAPEC-395\n\n## Reference: CAPEC-399 Cloning RFID Cards or Chips\n**CAPEC-399 Cloning RFID Cards or Chips (full record).** Abstraction: Detailed; Status: Draft; Severity: n/a; Likelihood: n/a\nAn attacker analyzes data returned by an RFID chip and uses this information to duplicate a RFID signal that responds identically to the target chip. 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.

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. Alternatively, the adversary can simply try to brute-force various encoding possibilities.\n\n**Execution flow.** . ****: [Survey the application for IP addresses as user input] Using a browser, an automated tool or by inspecting the application, an adversary records all entry points to the application where IP addresses are used.\n. ****: [Probe entry points to locate vulnerabilities] The adversary uses the entry points gathered in the \"Explore\" phase as a target list and attempts alternate IP address encodings, observing application behavior. 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.

The attacker sends command strings to the target terminal device hoping that the target user will hit enter and thereby execute the malicious command with their privileges. The attacker can send the results (such as copying /etc/passwd) to a known directory and collect once the attack has succeeded.\n\n**Prerequisites.** - User terminals must have a permissive access control such as world writeable that allows normal users to control data on other user's terminals.\n\n**Skills required.** - Ability to discover permissions on terminal devices.

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.

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.

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. This attack pattern is included in CAPEC for historical purposes.\n\n**Prerequisites.** - System must use weak authentication mechanisms for administrative functions.\n\n**Skills required.** - Given a vulnerable phone system, the attackers' technical vector relies on attacks that are well documented in cracker 'zines and have been around for decades.\n\n**Resources required.** CCITT-5 or other vulnerable lines, with the ability to send tones such as combined 2,400 Hz and 2,600 Hz tones to the switch\n\n**Mitigations.** - Implementation: Upgrade phone lines.

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 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.

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. If variables that serve as URLs that the Flash application references can be controlled through parameters, then by creating a link that includes values for those parameters, an attacker can cause arbitrary content to be referenced and possibly executed by the targeted Flash application.\n\n**Prerequisites.** - The targeted Flash application must reference external URLs and the locations thus referenced must be controllable through parameters.

Some operating systems or router firmware reverse the bit order of the ID field when echoing the IP Header portion of the original datagram within an ICMP error message.\n\n## Reference: CAPEC-306 TCP Window Scan\n**CAPEC-306 TCP Window Scan (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary engages in TCP Window scanning to analyze port status and operating system type. TCP Window scanning uses the ACK scanning method but examine the TCP Window Size field of response RST packets to make certain inferences. While TCP Window Scans are fast and relatively stealthy, they work against fewer TCP stack implementations than any other type of scan. 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. TCP Window scanning is one of the most complex scan types, and its results are difficult to interpret. Window scanning alone rarely yields useful information, but when combined with other types of scanning is more useful. It is a generally more reliable means of making inference about operating system versions than port status.\n\n**Prerequisites.** - TCP Window scanning requires the use of raw sockets, and thus cannot be performed from some Windows systems (Windows XP SP 2, for example). On Unix and Linux, raw socket manipulations require root privileges.\n\n**Resources required.** The ability to send TCP segments with a custom window size to a host during network reconnaissance. This can be achieved 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 TCP packets with the ACK flag set and that are not associated with an existing connection to target ports.\n. ****: An adversary uses the response from the target to determine the port's state. Specifically, the adversary views the TCP window size from the returned RST packet if one was received. Depending on the target operating system, a positive window size may indicate an open port while a negative window size may indicate a closed port.

UDP scanning methods involve sending a UDP datagram to the target port and looking for evidence that the port is closed. Open UDP ports usually do not respond to UDP datagrams as there is no stateful mechanism within the protocol that requires building or establishing a session. Responses to UDP datagrams are therefore application specific and cannot be relied upon as a method of detecting an open port. UDP scanning relies heavily upon ICMP diagnostic messages in order to determine the status of a remote port.\n\n**Prerequisites.** - The ability to send UDP datagrams to a host and receive ICMP error messages from that host. In cases where particular types of ICMP messaging is disallowed, the reliability of UDP scanning drops off sharply.\n\n**Resources required.** The ability to craft custom UDP Packets for use during network reconnaissance. This can be accomplished via the use of a port scanner, or via socket manipulation in a programming or scripting language. Packet injection tools are also useful. It is also necessary to trap ICMP diagnostic messages during this process. 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 UDP packets to target ports.\n. ****: An adversary uses the response from the target to determine the port's state. Whether a port responds to a UDP packet is dependant on what application is listening on that port. No response does not indicate the port is not open.\n\n**Mitigations.** - Firewalls or ACLs which block egress ICMP error types effectively prevent UDP scans from returning any useful information.\n- UDP scanning is complicated by rate limiting mechanisms governing ICMP error messages.\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)\n\n## Reference: CAPEC-309 Network Topology Mapping\n**CAPEC-309 Network Topology Mapping (full record).** Abstraction: Standard; Status: Draft; Severity: Low; Likelihood: n/a\nAn adversary engages in scanning activities to map network nodes, hosts, devices, and routes.

There are several different forms of this attack. The first form of this attack involves accessing HTTP Cookies to mine for potentially sensitive data contained therein. The second form involves intercepting this data as it is transmitted from client to server. This intercepted information is then used by the adversary to impersonate the remote user/session. The third form is when the cookie's content is modified by the adversary before it is sent back to the server. Here the adversary seeks to convince the target server to operate on this falsified information.\n\n**Prerequisites.** - Target server software must be a HTTP daemon that relies on cookies.\n- The cookies must contain sensitive information.\n- The adversary must be able to make HTTP requests to the server, and the cookie must be contained in the reply.\n\n**Skills required.** - To overwrite session cookie data, and submit targeted attacks via HTTP\n- Exploiting a remote buffer overflow generated by attack\n\n**Resources required.** A utility that allows for the viewing and modification of cookies.

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.

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.

Framing is information and experiences in life that alter the way we react to decisions we must make. This type of persuasive technique exploits the way people are conditioned to perceive data and its significance, while avoiding negative or avoidance responses from the target. Rather than a specific technique framing is a methodology of conversation that slowly encourages the target to adopt to the adversary's perspective. One technique of framing is to avoid the use of the word \"No\" and to contextualize responses in a manner that is positive.

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. The attacker will need to observe the application's/system's response to the encoded data to determine whether the data was interpreted properly.\n. ****: [Combine multiple encodings accepted by the application.] The attacker now combines encodings accepted by the application. The attacker may combine different encodings or apply the same encoding multiple times.\n. […]"}]}

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.

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)"}]}

Host discovery is one of the earliest phases of network reconnaissance. The adversary usually starts with a range of IP addresses belonging to a target network and uses various methods to determine if a host is present at that IP address. Host discovery is usually referred to as 'Ping' scanning using a sonar analogy. The goal is to send a packet through to the IP address and solicit a response from the host. As such, a 'ping' can be virtually any crafted packet whatsoever, provided the adversary can identify a functional host based on its response.

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.

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.

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.. 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. Most common locks, such as domestic locks in the US, can be picked using a standard 2 tools (i.e. a torsion wrench and a hook pick).\n\n## Classification\n- Abstraction: Detailed\n- Status: Draft\n- Typical severity: n/a\n- Likelihood of attack: n/a\n\n## Reference: CAPEC-1 Accessing Functionality Not Properly Constrained by ACLs\n**CAPEC-1 Accessing Functionality Not Properly Constrained by ACLs (full record).** Abstraction: Standard; Status: Draft; Severity: High; Likelihood: High\nIn applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. 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.

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.

Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. 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. They may then need to view a particular page in order to have the server execute the include directive and run a command or open a file on behalf of the adversary.\n\n**Mitigations.** - Set the OPTIONS IncludesNOEXEC in the global access.conf file or local.htaccess (Apache) file to deny SSI execution in directories that do not need them\n- All user controllable input must be appropriately sanitized before use in the application.

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.

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.

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 may be accomplished by comparing some manipulation of the secret to a known value, use of the secret to manipulate some known set of data and determining if the result displays specific characteristics (for example, turning cryptotext into plaintext), or by submitting the secret to some external authority and having the external authority respond as to whether the value was the correct secret. Ideally, the attacker will want to determine the correctness of their guess independently since involvement of an external authority is usually slower and can provide an indication to the defender that a brute-force attack is being attempted.\n. ****: [Reduce search space] Find ways to reduce the secret space.

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.

This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.\n\n**Prerequisites.** - The target must transmit data over a medium that is accessible to the adversary.\n\n**Resources required.** The adversary must have the necessary technology to intercept information passing between the nodes of a network. For TCP/IP, the capability to run tcpdump, ethereal, etc. can be useful. Depending upon the data being targeted the technological requirements will change.\n\n**Mitigations.** - Leverage encryption to encode the transmission of data thus making it accessible only to authorized parties.\n\n**Consequences.** - None (None)\n\n**Underlying weaknesses.** - CWE-319 (Cleartext Transmission of Sensitive Information)"}]}

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.

These attacks use legitimate session-based HTTP GET requests designed to consume large amounts of a server's resources. 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. Third party providers have dedicated resources and expertise that could allow them to update rules and prevent HTTP Floods very quickly.\n- Design: Use a load balancer such as nginx to prevent small scale HTTP Floods by dispersing traffic between a group of servers.\n- Implementation: Make a requesting machine solve some kind of challenge before allowing them to send an HTTP request.

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.

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.

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.

A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initially loaded, while a DOM-based attack executes sometime after the page loads. Another distinction of DOM-based attacks is that in some cases, the malicious script is never sent to the vulnerable web server at all.

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.

This type of persuasive technique exploits the way people are conditioned to perceive data and its significance, while avoiding negative or avoidance responses from the target. Rather than a specific technique framing is a methodology of conversation that slowly encourages the target to adopt to the adversary's perspective.

In situations of uncertainty, people tend to behave in ways they see others behaving. The adversary convinces the target of adopting behavior or actions that is advantageous to the adversary.\n\n## Mitigations\n- An organization should provide regular, robust cybersecurity training to its employees to prevent social engineering attacks.\n\n## Consequences\n- None (None)\n\n## Reference: CAPEC-3 Using Leading 'Ghost' Character Sequences to Bypass Input Filters\n**CAPEC-3 Using Leading 'Ghost' Character Sequences to Bypass Input Filters (full record).** Abstraction: Detailed; Status: Draft; Severity: Medium; Likelihood: Medium\nSome APIs will strip certain leading characters from a string of parameters. 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.

Any service or application available for TCP or UDP networking will have a port open for communications over the network.\n\n**Prerequisites.** - The adversary requires logical access to the target's network in order to carry out this type of attack.\n\n**Resources required.** The adversary requires a network mapping/scanning tool, or must conduct socket programming on the command line.

The scanning process involves completing a 'three-way handshake' with a remote port, and reports the port as closed if the full handshake cannot be established. An advantage of TCP connect scanning is that it works against any TCP/IP stack.\n\n**Prerequisites.** - The adversary requires logical access to the target network. The TCP connect Scan requires the ability to connect to an available port and complete a 'three-way-handshake' This scanning technique does not require any special privileges in order to perform. This type of scan works against all TCP/IP stack implementations.\n\n**Resources required.** The adversary can leverage a network mapper or scanner, or perform this attack via routine 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 to see the response.\n\n**Execution flow.** . ****: An adversary attempts to initialize a TCP connection with with the target port.\n. ****: An adversary uses the result of their TCP connection to determine the state of the target port. A successful connection indicates a port is open with a service listening on it while a failed connection indicates the port is not open.\n\n**Mitigations.** - Employ a robust network defense posture that includes an IDS/IPS system.\n\n**Consequences.** - None (None)\n\n**Related patterns.** - ChildOf: CAPEC-300\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n\n## Reference: CAPEC-302 TCP FIN Scan\n**CAPEC-302 TCP FIN Scan (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: n/a\nAn adversary uses a TCP FIN scan to determine if ports are closed on the target machine. This scan type is accomplished by sending TCP segments with the FIN bit set in the packet header. 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. This behavior should allow the adversary to scan for closed ports by sending certain types of rule-breaking packets (out of sync or disallowed by the TCB) and detect closed ports via RST packets.\n\n**Prerequisites.** - FIN scanning requires the use of raw sockets, and thus cannot be performed from some Windows systems (Windows XP SP 2, for example). On Unix and Linux, raw socket manipulations require root privileges.\n\n**Resources required.** This attack pattern requires the ability to send TCP FIN segments to a host during network reconnaissance. This can be achieved 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 TCP packets with the FIN flag but not associated with an existing connection to target ports.\n. ****: An adversary uses the response from the target to determine the port's state. If no response is received the port is open. If a RST packet is received then the port is closed.\n\n**Mitigations.** - FIN scans are detected via heuristic (non-signature) based algorithms, much in the same way as other scan types are detected. An IDS/IPS system with heuristic algorithms is required to detect them.\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)"}]}

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."}]}

Not all operating systems implement timestamps within the TCP header, but when timestamps are used then this provides the attacker with a means to guess the operating system of the target. The attacker begins by probing any active TCP service in order to get response which contains a TCP timestamp. Different Operating systems update the timestamp value using different intervals. This type of analysis is most accurate when multiple timestamp responses are received and then analyzed. TCP timestamps can be found in the TCP Options field of the TCP header.\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.The target OS must support the TCP timestamp option in order to obtain a fingerprint.\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).

One common way to test TCP Sequence Number generation is to send a probe packet to an open port on the target and then compare the how the Sequence Number generated by the target relates to the Acknowledgement Number in the probe packet. Different operating systems assign Sequence Numbers differently, so a fingerprint of the operating system can be obtained by categorizing the relationship between the acknowledgement number and sequence number as follows: 1) the Sequence Number generated by the target is Zero, 2) the Sequence Number generated by the target is the same as the acknowledgement number in the probe, 3) the Sequence Number generated by the target is the acknowledgement number plus one, or 4) the Sequence Number is any other non-zero number.\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.** A tool capable of sending and receiving packets from a remote system.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Related patterns.** - ChildOf: CAPEC-312\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)"}]}

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.

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 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.

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. UDP attacks can also target services like DNS or VoIP which utilize these protocols. Additionally, due to the session-less nature of the UDP protocol, the source of a packet is easily spoofed making it difficult to find the source of the attack.\n\n**Prerequisites.** - This type of an attack requires the ability to generate a large amount of UDP traffic to send to the desired port of a target service using UDP.\n\n**Mitigations.** - To mitigate this type of an attack, modern firewalls drop UDP traffic destined for closed ports, and unsolicited UDP reply packets. A variety of other countermeasures such as universal reverse path forwarding and remote triggered black holing(RFC3704) along with modifications to BGP like black hole routing and sinkhole routing(RFC3882) help mitigate the spoofed source IP nature of these attacks.\n\n**Related patterns.** - ChildOf: CAPEC-125\n\n**Underlying weaknesses.** - CWE-770 (Allocation of Resources Without Limits or Throttling)"}]}

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.

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.

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.

This is an ftpd glob Expansion LIST Heap Overflow Vulnerability. ftp daemon contains a heap-based buffer overflow condition. The overflow occurs when the LIST command is issued with an argument that expands into an oversized string after being processed by glob. This buffer overflow occurs in memory that is dynamically allocated. It may be possible for adversaries to exploit this vulnerability and execute arbitrary code on the affected host. To exploit this, the adversary must be able to create directories on the target host. The glob function is used to expand short-hand notation into complete file names. By sending to the FTP server a request containing a tilde (~) and other wildcard characters in the pathname string, a remote adversary can overflow a buffer and execute arbitrary code on the FTP server to gain root privileges. Once the request is processed, the glob function expands the user input, which could exceed the expected length. In order to exploit this vulnerability, the adversary must be able to create directories on the FTP server. [REF-1] Buffer overflow in the glob implementation in libc in NetBSD-current before 20050914, and NetBSD 2.* and 3.* before 20061203, as used by the FTP daemon, allows remote authenticated users to execute arbitrary code via a long pathname that results from path expansion.

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. If the intent is to simply cause the software to crash, the input needs only to expand to an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary will craft input that expands in a way that not only overflows the targeted buffer but does so in such a way that the overwritten return address is replaced with one of the adversaries' choosing which points to code injected by the adversary.\n. ****: [Overflow the buffer] Using the injection vector, the adversary gives the crafted input to the program, overflowing the buffer.\n\n## Mitigations\n- Ensure that when parameter expansion happens in the code that the assumptions used to determine the resulting size of the parameter are accurate and that the new size of the parameter is visible to the whole system\n\n## Underlying weaknesses\n- CWE-120 (Buffer Copy without Checking Size of Input ('Classic Buffer Overflow'))\n- CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)\n- CWE-118 (Incorrect Access of Indexable Resource ('Range Error'))\n- CWE-130 (Improper Handling of Length Parameter Inconsistency)\n- CWE-131 (Incorrect Calculation of Buffer Size)\n- CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'))\n- CWE-20 (Improper Input Validation)\n- CWE-680 (Integer Overflow to Buffer Overflow)\n- CWE-697 (Incorrect Comparison)\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.

This is an ftpd glob Expansion LIST Heap Overflow Vulnerability. ftp daemon contains a heap-based buffer overflow condition. The overflow occurs when the LIST command is issued with an argument that expands into an oversized string after being processed by glob.\n- This buffer overflow occurs in memory that is dynamically allocated. It may be possible for adversaries to exploit this vulnerability and execute arbitrary code on the affected host.\n- To exploit this, the adversary must be able to create directories on the target host.\n- The glob function is used to expand short-hand notation into complete file names. By sending to the FTP server a request containing a tilde (~) and other wildcard characters in the pathname string, a remote adversary can overflow a buffer and execute arbitrary code on the FTP server to gain root privileges. Once the request is processed, the glob function expands the user input, which could exceed the expected length. In order to exploit this vulnerability, the adversary must be able to create directories on the FTP server.\n- [REF-1]\n- Buffer overflow in the glob implementation in libc in NetBSD-current before 20050914, and NetBSD 2.* and 3.* before 20061203, as used by the FTP daemon, allows remote authenticated users to execute arbitrary code via a long pathname that results from path expansion.\n- The limit computation of an internal buffer was done incorrectly. The size of the buffer in byte was used as element count, even though the elements of the buffer are 2 bytes long.

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.

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.

This type of analysis is also referred to as Reverse Code Engineering, as techniques exist for extracting source code from an executable. Several techniques are often employed for this purpose, both black box and white box. The use of computer bus analyzers and packet sniffers allows the binary to be studied at a level of interactions with its computing environment, such as a host OS, inter-process communication, and/or network communication. This type of analysis falls into the 'black box' category because it involves behavioral analysis of the software without reference to source code, object code, or protocol specifications.\n\n**Resources required.** Access to the target file such that it can be analyzed with the appropriate tools.

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.

These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process.

Content served by a vulnerable web application includes script code used to manipulate the Document Object Model (DOM). This script code either does not properly validate input, or does not perform proper output encoding, thus creating an opportunity for an adversary to inject a malicious script launch a XSS attack. A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initially loaded, while a DOM-based attack executes sometime after the page loads. Another distinction of DOM-based attacks is that in some cases, the malicious script is never sent to the vulnerable web server at all.

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. Access can be redirected through a number of techniques, including the use of symbolic links, search path modification, and relative path manipulation.\n\n**Prerequisites.** - The target must utilize external libraries and must fail to verify the integrity of these libraries before using them.\n\n**Skills required.** - To modify the entries in the configuration file pointing to malicious libraries\n- To force symlink and timing issues for redirecting access to libraries\n- To reverse engineering the libraries and inject malicious code into the libraries\n\n**Execution flow.** . ****: [Identify Target] The adversary identifies the target application and determines what libraries are being used.\n. ****: [Deploy Malicious Libraries] The adversary crafts malicious libraries and deploys them on the system where the application is running, or in a remote location that can be loaded by the application.\n. ****: [Redirect Library Calls to Malicious Library] Once the malicious library crafted by the adversary is deployed, the adversary will manipulate the flow of the application such that it calls the malicious library.

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.

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.

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).

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.

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.

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.. 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. Unlike bump keys or lock picks, a Snap Gun may damage the lock more easily, leaving evidence that the lock has been tampered with."}]}

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.

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.

The developed product is adjusted and configured to handle what it believes to be a heavy network load, but when deployed at the victim site the large volumes of network traffic are dropped instead of being processed by the network security device.

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.

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).

Optionally, ability to capture output directly through synchronous communication or other method such as FTP.\n\n**Mitigations.** - Design: Enforce principle of least privilege\n- Design: Run server interfaces with a non-root account and/or utilize chroot jails or other configuration techniques to constrain privileges even if attacker gains some limited access to commands.\n- Implementation: Perform testing such as pen-testing and vulnerability scanning to identify directories, programs, and interfaces that grant direct access to executables.\n- Implementation: Implement host integrity monitoring to detect any unwanted altering of configuration files.\n- Implementation: Ensure that files that are not required to execute, such as configuration files, are not over-privileged, i.e. not allowed to execute.\n\n**Consequences.** - None (None)\n- None (None)\n- None (None)\n\n**Example instances.** - Another example targets clients reading pdf files.

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. Web service digging tools may be helpful.\n\n**Execution flow.** . ****: [Identify services] Discover a service of interest by exploring service registry listings or by connecting on a known port or some similar means.\n. ****: [Authenticate to service] Authenticate to the service, if required, in order to explore it.\n. ****: [Identify all interfaces] Determine the exposed interfaces by querying the registry as well as probably sniffing to expose interfaces that are not explicitly listed.\n. ****: [Attempt to discover unpublished functions] Using manual or automated means, discover unpublished or undocumented functions exposed by the service.\n. ****: [Exploit unpublished functions] Using information determined via experimentation, exploit the unpublished features of the service.\n\n**Mitigations.** - Authenticating both services and their discovery, and protecting that authentication mechanism simply fixes the bulk of this problem.

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. Attacks of this nature do not require network access or undue CPU, memory, or other hardware-based resources.\n\n**Execution flow.** . ****: [Identify Target] Attacker identifies client components to extract information from. These may be binary executables, class files, shared libraries (e.g., DLLs), configuration files, or other system files.\n. ****: [Retrieve Embedded Data] The attacker then uses a variety of techniques, such as sniffing, reverse-engineering, and cryptanalysis to retrieve the information of interest.

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. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution. […]"}]}

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.

One example could be harvesting lists of usernames or userIDs for the purpose of sending spam messages to those users. One example of this type of attack involves the adversary creating an event within the sub-application. Assume the adversary hosts a \"virtual sale\" of rare items. As other users enter the event, the attacker records via AiTM (CAPEC-94) proxy the user_ids and usernames of everyone who attends.

Performing this attack can allow the attacker to gain unauthorized privileges within the application, or conduct attacks such as phishing, deceptive strategies to spread malware, or traditional web-application attacks. 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.

Some applications make navigation remapping more difficult to detect because the actual HREF values of images, profile elements, and links/buttons are masked. One example would be to place an image in a user's photo gallery that when clicked upon redirected the user to an off-site location.

Network sniffing applications can reveal TCP/IP, DNS, Ethernet, and other low-level network communication information. The adversary takes a passive role in this attack pattern and simply observes and analyzes the traffic.

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. Access can be redirected through a number of techniques, including the use of symbolic links, search path modification, and relative path manipulation.\n\n**Prerequisites.** - The target must utilize external libraries and must fail to verify the integrity of these libraries before using them.\n\n**Skills required.** - To modify the entries in the configuration file pointing to malicious libraries\n- To force symlink and timing issues for redirecting access to libraries\n- To reverse engineering the libraries and inject malicious code into the libraries\n\n**Execution flow.** . ****: [Identify Target] The adversary identifies the target application and determines what libraries are being used.\n. ****: [Deploy Malicious Libraries] The adversary crafts malicious libraries and deploys them on the system where the application is running, or in a remote location that can be loaded by the application.\n. ****: [Redirect Library Calls to Malicious Library] Once the malicious library crafted by the adversary is deployed, the adversary will manipulate the flow of the application such that it calls the malicious library.

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.

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.

The adversary usually starts with a range of IP addresses belonging to a target network and uses various methods to determine if a host is present at that IP address. Host discovery is usually referred to as 'Ping' scanning using a sonar analogy. The goal is to send a packet through to the IP address and solicit a response from the host. As such, a 'ping' can be virtually any crafted packet whatsoever, provided the adversary can identify a functional host based on its response. An attack of this nature is usually carried out with a 'ping sweep,' where a particular kind of ping is sent to a range of IP addresses.\n\n**Prerequisites.** - The adversary requires logical access to the target network in order to carry out host discovery.\n\n**Resources required.** The resources required will differ based upon the type of host discovery being performed.

Editing registry information can permit the adversary to hide configuration information or remove indicators of compromise to cover up activity. Many applications utilize registries to store configuration and service information. As such, modification of registry information can affect individual services (affecting billing, authorization, or even allowing for identity spoofing) or the overall configuration of a targeted application. For example, both Java RMI and SOAP use registries to track available services. Changing registry values is sometimes a preliminary step towards completing another attack pattern, but given the long term usage of many registry values, manipulation of registry information could be its own end.\n\n**Prerequisites.** - The targeted application must rely on values stored in a registry.\n- The adversary must have a means of elevating permissions in order to access and modify registry content through either administrator privileges (e.g., credentialed access), or a remote access tool capable of editing a registry through an API.\n\n**Skills required.** - The adversary requires privileged credentials or the development/acquiring of a tailored remote access tool.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\n\n**Mitigations.** - Ensure proper permissions are set for Registry hives to prevent users from modifying keys.\n- Employ a robust and layered defensive posture in order to prevent unauthorized users on your system.\n- Employ robust identification and audit/blocking using an allowlist of applications on your system.

Many applications that communicate with remote entities or which perform intensive calculations utilize caches to improve efficiency. However, if the application computes or receives sensitive information and the cache is not appropriately protected, an attacker can browse the cache and retrieve this information. This can result in the disclosure of sensitive information.\n\n**Prerequisites.** - The target application must store sensitive information in a cache.\n- The cache must be inadequately protected against attacker access.\n\n**Resources required.** The attacker must be able to reach the target application's cache. 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**Execution flow.** . ****: [Identify Application Cache] An adversary first identifies an application that utilizes a cache. This could either be a web application storing data in a browser cache, or an application running on a separate machine.

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.

The goal of the adversary is to access directories and files that are intended to be restricted from their access.\n\n**Prerequisites.** - The target must leverage and access an underlying file system.\n\n**Skills required.** - Simple command line attacks.\n- Programming attacks.\n\n**Resources required.** The attacker must have access to an application interface or a direct shell that allows them to inject directory strings and monitor the results.\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 absolute file paths on all found user input locations and observes the responses.\n. ****: [Access, modify, or execute arbitrary files.] An adversary injects absolute path traversal syntax into identified vulnerable inputs to cause inappropriate reading, writing or execution of files. An adversary could be able to read directories or files which they are normally not allowed to read. The adversary could also access data outside the web document root, or include scripts, source code and other kinds of files from external websites. Once the adversary accesses arbitrary files, they could also modify files. In particular situations, the adversary could also execute arbitrary code or system commands.\n\n**Mitigations.** - Design: Configure the access control correctly.\n- Design: Enforce principle of least privilege.\n- Design: Execute programs with constrained privileges, so parent process does not open up further vulnerabilities.

This technique requires an On-path or In-path device that can monitor and respond to the target's DNS requests. This attack differs from BGP Tampering in that it directly responds to requests made by the target instead of polluting the routing the target's infrastructure uses.\n\n**Prerequisites.** - On/In Path Device\n\n**Skills required.** - To distribute email\n\n**Mitigations.** - Design: Avoid dependence on DNS\n- Design: Include \"hosts file\"/IP address in the application\n- Implementation: Utilize a.onion domain with Tor support\n- Implementation: DNSSEC\n- Implementation: DNS-hold-open\n\n**Related patterns.** - ChildOf: CAPEC-194\n\n## Reference: CAPEC-599 Terrestrial Jamming\n**CAPEC-599 Terrestrial Jamming (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: Low\nIn this attack pattern, the adversary transmits disruptive signals in the direction of the target's consumer-level satellite dish (as opposed to the satellite itself). The transmission disruption occurs in a more targeted range. Portable terrestrial jammers have a range of 3-5 kilometers in urban areas and 20 kilometers in rural areas. 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.

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.

Typically, the adversary conducts a covert channel attack to target non-discarded microarchitectural changes caused by transient executions such as speculative execution, branch prediction, instruction pipelining, and/or out-of-order execution. The transient execution results in a series of instructions (gadgets) which construct covert channel and access/transfer the secret data.\n\n**Prerequisites.** - The adversary needs at least user execution access to a system and a maliciously crafted program/application/process with unprivileged code to misuse transient instruction set execution of the CPU.\n\n**Skills required.** - Detailed knowledge on how various CPU architectures and microcode perform transient execution for various low-level assembly language code instructions/operations.\n- Detailed knowledge on compiled binaries and operating system shared libraries of instruction sequences, and layout of application and OS/Kernel address spaces for data leakage.\n\n**Resources required.** C2C mechanism or direct access to victim system, capable of dropping malicious program and collecting covert channel attack data.

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.

Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device.

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."}]}

Not all operating systems implement timestamps within the TCP header, but when timestamps are used then this provides the attacker with a means to guess the operating system of the target. The attacker begins by probing any active TCP service in order to get response which contains a TCP timestamp. Different Operating systems update the timestamp value using different intervals. This type of analysis is most accurate when multiple timestamp responses are received and then analyzed. TCP timestamps can be found in the TCP Options field of the TCP header.\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.The target OS must support the TCP timestamp option in order to obtain a fingerprint.\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).

One common way to test TCP Sequence Number generation is to send a probe packet to an open port on the target and then compare the how the Sequence Number generated by the target relates to the Acknowledgement Number in the probe packet. Different operating systems assign Sequence Numbers differently, so a fingerprint of the operating system can be obtained by categorizing the relationship between the acknowledgement number and sequence number as follows: 1) the Sequence Number generated by the target is Zero, 2) the Sequence Number generated by the target is the same as the acknowledgement number in the probe, 3) the Sequence Number generated by the target is the acknowledgement number plus one, or 4) the Sequence Number is any other non-zero number.\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.** A tool capable of sending and receiving packets from a remote system.\n\n**Consequences.** - None (None)\n- None (None)\n\n**Related patterns.** - ChildOf: CAPEC-312\n\n**Underlying weaknesses.** - CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)\n\n## Reference: CAPEC-322 TCP (ISN) Greatest Common Divisor Probe\n**CAPEC-322 TCP (ISN) Greatest Common Divisor Probe (full record).** Abstraction: Detailed; Status: Stable; Severity: Low; Likelihood: Medium\nThis OS fingerprinting probe sends a number of TCP SYN packets to an open port of a remote machine.

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.

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.

The adversary must be able to observe, read, and/or hear the communication traffic, but not necessarily block the communication or change its content. 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. Depending on the medium of transmission and the path the data takes between the sender and recipient, the adversary may require special equipment and/or require that this equipment be placed in specific locations (e.g., a network sniffing tool)\n\n**Execution flow.** . ****: [Determine Communication Mechanism] The adversary determines the nature and mechanism of communication between two components, looking for opportunities to exploit.\n. ****: [Position In Between Targets] The adversary positions themselves somewhere in the middle of the two components.

Network sniffing applications can reveal TCP/IP, DNS, Ethernet, and other low-level network communication information. The adversary takes a passive role in this attack pattern and simply observes and analyzes the traffic. The adversary may precipitate or indirectly influence the content of the observed transaction, but is never the intended recipient of the target information.\n\n**Prerequisites.** - The target must be communicating on a network protocol visible by a network sniffing application.\n- The adversary must obtain a logical position on the network from intercepting target network traffic is possible.

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. Access can be redirected through a number of techniques, including the use of symbolic links, search path modification, and relative path manipulation.\n\n**Prerequisites.** - The target must utilize external libraries and must fail to verify the integrity of these libraries before using them.\n\n**Skills required.** - To modify the entries in the configuration file pointing to malicious libraries\n- To force symlink and timing issues for redirecting access to libraries\n- To reverse engineering the libraries and inject malicious code into the libraries\n\n**Execution flow.** . ****: [Identify Target] The adversary identifies the target application and determines what libraries are being used.\n. ****: [Deploy Malicious Libraries] The adversary crafts malicious libraries and deploys them on the system where the application is running, or in a remote location that can be loaded by the application.\n. ****: [Redirect Library Calls to Malicious Library] Once the malicious library crafted by the adversary is deployed, the adversary will manipulate the flow of the application such that it calls the malicious library.

This is a specific instance of the password brute forcing attack pattern. Dictionary Attacks differ from similar attacks such as Password Spraying (CAPEC-565) and Credential Stuffing (CAPEC-600), since they leverage unknown username/password combinations and don't care about inducing account lockouts.\n\n**Prerequisites.** - The system uses one factor password based authentication.\n- The system does not have a sound password policy that is being enforced.\n- The system does not implement an effective password throttling mechanism.\n\n**Skills required.** - A variety of password cracking tools and dictionaries are available to launch this type of an attack.\n\n**Resources required.** A machine with sufficient resources for the job (e.g. CPU, RAM, HD).

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.

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. This attack pattern is included in CAPEC for historical purposes.\n\n**Prerequisites.** - System must use weak authentication mechanisms for administrative functions.\n\n**Skills required.** - Given a vulnerable phone system, the attackers' technical vector relies on attacks that are well documented in cracker 'zines and have been around for decades.\n\n**Resources required.** CCITT-5 or other vulnerable lines, with the ability to send tones such as combined 2,400 Hz and 2,600 Hz tones to the switch\n\n**Mitigations.** - Implementation: Upgrade phone lines.

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 BGP protocol helps traffic move throughout the Internet by selecting the most efficient route between Autonomous Systems (AS), or routing domains. BGP is the basis for interdomain routing infrastructure, providing connections between these ASs. By suppressing the intended AS routing advertisements and/or forcing less effective routes for traffic to ASs, the adversary can deny availability for the target network.\n\n## Mitigations\n- Implement Ingress filters to check the validity of received routes. However, this relies on the accuracy of Internet Routing Registries (IRRs) databases which are often not well-maintained.\n- Implement Secure BGP (S-BGP protocol), which improves authorization and authentication capabilities based on public-key cryptography.\n\n## Consequences\n- None (None)\n\n## Reference: CAPEC-279 SOAP Manipulation\n**CAPEC-279 SOAP Manipulation (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: Medium\nSimple Object Access Protocol (SOAP) is used as a communication protocol between a client and server to invoke web services on the server. It is an XML-based protocol, and therefore suffers from many of the same shortcomings as other XML-based protocols. Adversaries can make use of these shortcomings and manipulate the content of SOAP paramters, leading to undesirable behavior on the server and allowing the adversary to carry out a number of further attacks.\n\n**Prerequisites.** - An application uses SOAP-based web service api.\n- An application does not perform sufficient input validation to ensure that user-controllable data is safe for an XML parser.\n- The targeted server either fails to verify that data in SOAP messages conforms to the appropriate XML schema, or it fails to correctly handle the complete range of data allowed by the schema.\n\n**Execution flow.** . ****: [Find target application] The adversary needs to identify an application that uses SOAP as a communication protocol.\n. ****: [Detect Incorrect SOAP Parameter Handling] The adversary tampers with the SOAP message parameters and looks for indications that the tampering caused a change in behavior of the targeted application.\n. ****: [Manipulate SOAP parameters] The adversary manipulates SOAP parameters in a way that causes undesirable behavior for the server.

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.

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.

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.

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.

If the password chosen by the user was a word within the dictionary, this attack will be successful (in the absence of other mitigations). This is a specific instance of the password brute forcing attack pattern. Dictionary Attacks differ from similar attacks such as Password Spraying (CAPEC-565) and Credential Stuffing (CAPEC-600), since they leverage unknown username/password combinations and don't care about inducing account lockouts.\n\n**Prerequisites.** - The system uses one factor password based authentication.\n- The system does not have a sound password policy that is being enforced.\n- The system does not implement an effective password throttling mechanism.\n\n**Skills required.** - A variety of password cracking tools and dictionaries are available to launch this type of an attack.\n\n**Resources required.** A machine with sufficient resources for the job (e.g. CPU, RAM, HD).

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 some variants of this attack, the attacker must be able to stand up their own services that mimic the services the targeted client intends to use.\n\n**Related patterns.** - CanPrecede: CAPEC-664\n\n**Underlying weaknesses.** - CWE-923 (Improper Restriction of Communication Channel to Intended Endpoints)\n\n## Reference: CAPEC-162 Manipulating Hidden Fields\n**CAPEC-162 Manipulating Hidden Fields (full record).** Abstraction: Detailed; Status: Draft; Severity: High; Likelihood: n/a\nAn adversary exploits a weakness in the server's trust of client-side processing by modifying data on the client-side, such as price information, and then submitting this data to the server, which processes the modified data. 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 adversary observes the response from the server to determine if the values of each hidden field are being validated.\n. ****: [Manipulate hidden fields] Once the adversary has determined which hidden fields are not being validated by the server, they will manipulate them to change the normal behavior of the web application in a way that benefits the adversary.\n\n**Related patterns.** - ChildOf: CAPEC-77\n\n**Underlying weaknesses.** - CWE-602 (Client-Side Enforcement of Server-Side Security)"}]}

Even when the precise location of a targeted resource may not be known, naming conventions may indicate a small area of the target machine's file tree where the resources are typically located. For example, configuration files are normally stored in the /etc director on Unix systems. Adversaries can take advantage of this to commit other types of attacks.\n\n**Prerequisites.** - The targeted applications must either expect files to be located at a specific location or, if the location of the files can be configured by the user, the user either failed to move the files from the default location or placed them in a conventional location for files of the given type.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.

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.

Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the adversary access to the execution stack and execute arbitrary code in the target process.\n\n**Prerequisites.** - Target software processes binary resource files.\n- Target software contains a buffer overflow vulnerability reachable through input from a user-controllable binary resource file.\n\n**Skills required.** - To modify file, deceive client into downloading, locate and exploit remote stack or heap vulnerability\n\n**Execution flow.** . ****: [Identify target software] The adversary identifies software that uses external binary files in some way. This could be a file upload, downloading a file from a shared location, or other means.\n. ****: [Find injection vector] The adversary creates a malicious binary file by altering the header to make the file seem shorter than it is. Additional bytes are added to the end of the file to be placed in the overflowed location. The adversary then deploys the file to the software to determine if a buffer overflow was successful.\n. ****: [Craft overflow content] Once the adversary has determined that this attack is viable, they will specially craft the binary file in a way that achieves the desired behavior. If the source code is available, the adversary can carefully craft the malicious file so that the return address is overwritten to an intended value. If the source code is not available, the adversary will iteratively alter the file in order to overwrite the return address correctly.\n. ****: [Overflow the buffer] Once the adversary has constructed a file that will effectively overflow the targeted software in the intended way.

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. This attack pattern is included in CAPEC for historical purposes.\n\n**Prerequisites.** - System must use weak authentication mechanisms for administrative functions.\n\n**Skills required.** - Given a vulnerable phone system, the attackers' technical vector relies on attacks that are well documented in cracker 'zines and have been around for decades.\n\n**Resources required.** CCITT-5 or other vulnerable lines, with the ability to send tones such as combined 2,400 Hz and 2,600 Hz tones to the switch\n\n**Mitigations.** - Implementation: Upgrade phone lines.

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. 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)"}]}

This allows the adversary to sneak prohibited commands past filters and perform normally prohibited operations. Invalid characters may include null, carriage return, line feed or tab in an identifier. Successful bypassing of the filter can result in a XSS attack, resulting in the disclosure of web cookies or possibly other results.\n\n**Prerequisites.** - The target must fail to remove invalid characters from input and fail to adequately scan beyond these characters.\n\n**Resources required.** None: No specialized resources are required to execute this type of attack.\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.

This type of attack is possible when untrusted values are used to build these command strings. Weaknesses in input validation or command construction can enable the attack and lead to successful exploitation.\n\n**Prerequisites.** - The target application must accept input from the user and then use this input in the construction of commands to be executed.

This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.\n\n**Prerequisites.** - The target must transmit data over a medium that is accessible to the adversary.\n\n**Resources required.** The adversary must have the necessary technology to intercept information passing between the nodes of a network. For TCP/IP, the capability to run tcpdump, ethereal, etc. can be useful.

This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.\n\n**Prerequisites.** - Information and client-sensitive (and client-specific) data must be present through a distribution channel available to all users.\n- Distribution means must code (through channel, message identifiers, or convention) message destination in a manner visible within the distribution means itself (such as a control channel) or in the messages themselves.\n\n**Skills required.** - All the adversary needs to discover is the format of the messages on the channel/distribution means and the particular identifier used within the messages.\n\n**Resources required.** The adversary needs the ability to control source code or application configuration responsible for selecting which message/channel id is absorbed from the public distribution means.\n\n**Execution flow.** . ****: [Determine Nature of Messages] Determine the nature of messages being transported as well as the identifiers to be used as part of the attack\n. ****: [Authenticate] If required, authenticate to the distribution channel\n. ****: [Identify Known Client Identifiers] If any particular client's information is available through a control channel available to all users, the adversary will discover particular identifiers for targeted clients by observing this channel, or requesting client information through this channel.\n. ****: [Change Message Identifier] Adversaries with client access connecting to output channels could change their channel identifier and see someone else's (perhaps more privileged) data.\n\n**Mitigations.** - Associate some ACL (in the form of a token) with an authenticated user which they provide middleware. […]\n\n## Reference: CAPEC-120 Double Encoding\n**CAPEC-120 Double Encoding (full record).** Abstraction: Detailed; Status: Draft; Severity: Medium; Likelihood: Low\nThe adversary utilizes a repeating of the encoding process for a set of characters (that is, character encoding a character encoding of a character) to obfuscate the payload of a particular request. This may allow the adversary to bypass filters that attempt to detect illegal characters or strings, such as those that might be used in traversal or injection attacks. Filters may be able to catch illegal encoded strings, but may not catch doubly encoded strings. For example, a dot (.), often used in path traversal attacks and therefore often blocked by filters, could be URL encoded as %2E. However, many filters recognize this encoding and would still block the request. In a double encoding, the % in the above URL encoding would be encoded again as %25, resulting in %252E which some filters might not catch, but which could still be interpreted as a dot (.) by interpreters on the target.\n\n**Prerequisites.** - The target's filters must fail to detect that a character has been doubly encoded but its interpreting engine must still be able to convert a doubly encoded character to an un-encoded character.\n- The application accepts and decodes URL string request.\n- The application performs insufficient filtering/canonicalization on the URLs.\n\n**Resources required.** Tools that automate encoding of data can assist the adversary in generating encoded strings.\n\n**Execution flow.** . ****: [Survey the application for user-controllable inputs] Using a browser, an automated tool or by inspecting the application, an attacker records all entry points to the application.\n. ****: [Probe entry points to locate vulnerabilities] Try double-encoding for parts of the input in order to try to get past the filters.

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.

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.
