🚀 Sl0ppy-ProtopolCheck is an advanced prototype pollution scanner designed to test multiple attack vectors, function hijacking, and privilege escalation in JavaScript applications. This cutting-edge tool is a must-have for offensive security and application security research.
✅ Key Features:
- Deep prototype pollution detection (
__proto__,constructor.prototype, direct injections) - Function hijacking (
JSON.parse,toString,valueOf,fetch) - Security function bypass (
hasOwnProperty,isAdmin,hasAccess) - Privilege escalation checks and stealth property detection
⚡ This tool is built for research purposes and remains private source.
You Should Know:
Here are some practical commands and code snippets related to prototype pollution and JavaScript security:
1. Detecting Prototype Pollution:
function isPolluted(obj) {
return obj.<strong>proto</strong> !== Object.prototype;
}
console.log(isPolluted({})); // false
console.log(isPolluted(Object.create(null))); // true
2. Preventing Prototype Pollution:
const safeObject = Object.create(null); // Creates an object with no prototype safeObject.key = 'value'; console.log(safeObject.<strong>proto</strong>); // undefined
3. Function Hijacking Example:
const originalFetch = window.fetch;
window.fetch = function(url, options) {
console.log(<code>Fetching: ${url}</code>);
return originalFetch(url, options);
};
4. Security Function Bypass:
const user = { isAdmin: false };
user.<strong>proto</strong>.isAdmin = true; // Prototype pollution
console.log(user.isAdmin); // true
5. Linux Command to Monitor JavaScript Files:
grep -r "eval(" /path/to/javascript/files
6. Windows Command to Check for Suspicious Processes:
Get-Process | Where-Object { $_.CPU -gt 90 }
7. Linux Command to Check for Open Ports:
netstat -tuln | grep LISTEN
8. Windows Command to List Running Services:
Get-Service | Where-Object { $_.Status -eq "Running" }
- Linux Command to Check for Unauthorized Changes in Files:
find /path/to/files -mtime -1
-
Windows Command to Check for Unauthorized Changes in Files:
Get-ChildItem -Path C:\path\to\files -Recurse | Where-Object { $_.LastWriteTime -gt (Get-Date).AddDays(-1) }
What Undercode Say:
Prototype pollution is a critical vulnerability in JavaScript applications that can lead to severe security breaches. Tools like Sl0ppy-ProtopolCheck are essential for identifying and mitigating these risks. By understanding how prototype pollution works and implementing secure coding practices, developers can significantly reduce the attack surface of their applications. Always validate and sanitize user inputs, avoid using unsafe functions like eval, and regularly audit your code for potential vulnerabilities. Stay ahead in the cybersecurity game by continuously updating your knowledge and tools.
