Description

According to its self-reported version number, the installation of MediaWiki running on the remote host is affected by a cross-site scripting vulnerability due to a failure to sanitize user-supplied input passed to certain HTML attributes when including a template inside a style directive when editing an entry. An attacker can exploit this flaw to inject arbitrary HTML and script code to be executed by a user's browser within the context of an affected site.
