The vulnerability is caused due to an error in the handling of file uploads in "gm-upload.cgi". This can be exploited to upload arbitrary files to a location inside the web root (e.g. PHP scripts). Successful exploitation requires that the user has file upload privileges (normally administrators). The vulnerability has been confirmed in version 1.3.1. Other versions may also be affected. SOLUTION: Move the upload directory out of the web root. This may affect functionality.
