Arjun

HTTP Parameter Discovery Suite

Introduction

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 25,980 parameter names.

The best part? It takes less than 30 seconds to go through this huge list while making just 50-60 requests to the target.
Want to know how Arjun does that? Here's how.
