  script_tag(name:"insight", value:"Horde/Form/Type.php contains a vulnerable class that handles
  image upload in forms. When the Horde_Form_Type_image method onSubmit() is called on uploads, it
  invokes the functions getImage() and _getUpload(), which uses unsanitized user input as a path to
  save the image. The unsanitized POST parameter object[photo][img][file] is saved in the
  $upload[img][file] PHP variable, allowing an attacker to manipulate the $tmp_file passed to
  move_uploaded_file() to save the uploaded file. By setting the parameter to (for example)
  ../usr/share/horde/static/bd.php, one can write a PHP backdoor inside the web root. The static/
  destination folder is a good candidate to drop the backdoor because it is always writable in
  Horde installations.");
