WordPress Plugin Zingiri Forums - 'language' Local File Inclusion

source: https://www.securityfocus.com/bid/56777/info

The Zingiri Forums plugin for WordPress is prone to a local file-include vulnerability because it fails to sufficiently sanitize user-supplied input.

An attacker can exploit this vulnerability to view files and execute local scripts in the context of the web server process. This may aid in further attacks.
