      'Description' => %q(
        This module exploits command execution vulnerability in PHP-Fusion 9.03.00 and prior versions.
        It is possible to execute commands in the system with ordinary user authority. No need admin privilage.
        There is almost no control in the avatar upload section in the profile edit area.
        Only a client-based control working with javascript. (Simple pre-check)
        If we do not care about this control, the desired file can be sent to the server via Interception-Proxies. 
        The module opens the meterpreter session for you by bypassing the controls.
