General Information

Commix (short for [comm]and [i]njection e[x]ploiter) is an automated tool written by Anastasios Stasinopoulos (@ancst) that can be used from web developers, penetration testers or even security researchers in order to test web-based applications with the view to find bugs, errors or vulnerabilities related to command injection attacks. By using this tool, it is very easy to find and exploit a command injection vulnerability in a certain vulnerable parameter or HTTP header.

Legal Disclaimer

With each commix run end users are obligated to agree with the following prelude message:

(!) Legal disclaimer: Usage of commix for attacking targets without prior mutual consent is illegal. 
It is the end user's responsibility to obey all applicable local, state and federal laws.
