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