Description
The ilGhera Carta Docente for WooCommerce plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.5.0 via the 'cert' parameter of the 'wccd-delete-certificate' AJAX action. This is due to insufficient file path validation before performing a file deletion. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, such as wp-config.php, which can make site takeover and remote code execution possible.
