Detailsinfo

A vulnerability was found in Stylemix Motors Plugin up to 1.4.125. It has been rated as problematic. This issue affects the function stm_listings_ajax_save_user_data of the component Path Validation. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is integrity, and availability. The summary by CVE is:

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the stm_listings_ajax_save_user_data function in all versions up to, and including, 1.4.125 This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Although deletion is bounded to wp-content/uploads (preventing removal of wp-config.php), any authenticated Subscriber can trivially exploit this because the required AJAX nonce is printed on every front-end page and the handler's stm_user_avatar_path meta is writable by any logged-in user against their own account.
