Description
The Motors – Car Dealership & Classified Listings plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'stm_f_s' parameter in versions 1.4.69 up to, and including, 1.4.124 due to insufficient input sanitization and output escaping. Values submitted when adding or editing a listing are saved as listing category term names with HTML-entity-encoded markup intact, even if the listing itself is held for moderation, and the front-end inventory filter dropdowns later insert these term names into the page as HTML. This makes it possible for authenticated attackers, with Subscriber-level access and above, who are permitted to submit or edit listings, to inject arbitrary web scripts that execute when a user views and uses an inventory filter that lists the injected term.
