arjun

This package can find query parameters for URL endpoints.

Web applications use parameters (or queries) to accept user input, take the following example into consideration.

http://api.example.com/v1/userinfo?id=751634589

This URL seems to load user information for a specific user id, but what if there exists a parameter named admin which when set to True makes the endpoint provide more information about the user? This is what Arjun does, it finds valid HTTP parameters with a huge default dictionary of 25,890 parameter names. It takes less than 10 seconds to go through this huge list while making just 50-60 requests to the target.

Some features:

• Supports GET/POST/POST-JSON/POST-XML requests;
• Automatically handles rate limits and timeouts;
• Export results to: BurpSuite, text or JSON file;
• Import targets from: BurpSuite, text file or a raw request file;
• Can passively extract parameters from JS or 3 external sources.

Arjun is useful for penetration testing (PENTEST) and network security analysis, serving as OSINT.
