Description
The Mang Board plugin for WordPress is vulnerable to Local File Inclusion via the '{mode}_type' request parameter in all versions up to, and including, 2.4.3, due to insufficient sanitization of the parameter before it is used to build the path of a board skin template passed to require(). Only a few fixed type names were filtered, so a POST request with a custom 'mode' value can send a matching '<mode>_type' value containing directory traversal sequences. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server through any page that shows a Mang Board board. This can be used to bypass access controls, obtain sensitive data, or achieve code execution where PHP files can be placed on the server.
