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.");
