Commix a short form for Command Injection Exploiter is an environment that web developers, penetration testers and even security researchers can use to test web applications in order to find bugs or vulnerabilities.

Commix is written in python programming language. That helps to find vulnerabilities related to command injection attacks. In Command injection attack the goal is to execute arbitrary commands on the host operating system via a vulnerable application. These attacks are possible when an application passes unsafe user supplied data (forms, cookies, HTTP headers etc.) to a system shell.

The arbitrary commands will be executed on successful command injection attack through vulnerable application. The features available in Commix include a set of options for specifying which parameters should be injected and to append the injection payloads. User can also define data in POST request as well as employ injection payload suffix and prefix string to exploit the target.

Moreover, it supports base64 encoding for multiple injection techniques (eval-based, time based or file based).
