WWBN AVideo 12.4 through 29.7.1 Path Traversal File Deletion via deleteImage.json.php
WWBN AVideo 12.4 through 29.7.1 contains a path traversal vulnerability in the ADs plugin deleteImage.json.php that allows authenticated users with custom ads to delete arbitrary files. Attackers can set the unvalidated is_regular_user parameter to another user's id or ../ sequences to delete other users' ads or files like videos/configuration.php, taking the site offline and re-exposing the installer.
