Description
The Mang Board plugin for WordPress is vulnerable to Insecure Direct Object Reference via the board API (mb_board AJAX action) in all versions up to, and including, 2.4.7, due to the delete ownership check validating the comment identified by 'comment_pid' instead of the targeted post when the request sets 'mode' to 'comment', while the post delete query is scoped only by the user-supplied 'board_pid'. The check also passes when the referenced comment does not exist. This makes it possible for unauthenticated attackers to delete arbitrary board posts, along with their comments, written by other users.
