Dear Security Professionals,

Command injection is an attack in which the goal is execution of arbitrary commands on the host operating system via a vulnerable application. Command injection attacks are possible when an application passes unsafe user supplied data (forms, cookies, HTTP headers etc.) to a system shell. In this attack, the attacker-supplied operating system commands are usually executed with the privileges of the vulnerable application. Command injection attacks are possible largely due to insufficient input validation.

This publication is a teaser version of the "Command Injection Compendium" written by Mr. Shritam Bhowmick.

Full release is available here.

Enjoy the hacking!
