Successful exploitation of this exploit requires the site to be configured to allow users to upload video files directly, which is disabled by default. If this feature is enabled, any file uploaded via the "add video" upload form will end up in http://[victim]/images/originalvideos/[your account's user id]/[unique file name]. This folder is not protected with an index, so if indexes are allowed retrieving the shell's filename is trivial.
