'Name' => "appRain CMF Arbitrary PHP File Upload Vulnerability",
'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.
