  					This module exploits a remote file inclusion flaw in the WordPress blogging
  				software plugin known as Advanced Custom Fields. The vulnerability allows for remote
  				file inclusion and remote code execution via the export.php script. The Advanced
  				Custom Fields plug-in versions 3.5.1 and below are vulnerable. This exploit only
  				works when the php option allow_url_include is set to On (Default Off).
