  after the registration. After this process the user crops and saves the image. Then a 'POST'
  request that contains user supplied name of the image is sent to the server for renaming and
  cropping of the image. As a result of this request, the name of the user-supplied image is
  changed with a MD5 value. This process can be conducted only when type of the image is JPG or
  PNG. An attacker can use this vulnerability in order to rename an arbitrary image file. By doing
  this, they could destroy the design of the web site.");
