Motors – Car Dealer, Classifieds & Listing <= 1.4.107 - Authenticated (Subscriber+) Arbitrary File Deletion via 'stm_dealer_logo_path' Parameter

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.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Motors 1.4.108 closes this, and updating the plugin is the step that ends it.
