What the vulnerability does

01Description

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 1.4.107. This is due to insufficient file path validation in the become-dealer logo upload flow. The plugin allows any authenticated user to set an arbitrary filesystem path via the profile update handler. This makes it possible for authenticated attackers, with subscriber level access and above, to delete arbitrary files on the server.
