The MediaWiki product implements support for internationalization which allows a user to specify the language of the web interface. There exists an arbitrary code execution vulnerability in MediaWiki. The flaw is caused by improper checking of the user supplied language option. An attacker can exploit this vulnerability to inject and execute arbitrary code on the vulnerable host. In an attack scenario where arbitrary code execution is successfull, the behavior of the target is dependent on the intention of the attacker.
