includes/libs/IEUrlExtension.php in the MediaWiki API in MediaWiki 1.19.x
before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 does not
properly detect extensions when there are an even number of “.” (period)
characters in a string, which allows remote attackers to conduct cross-site
scripting (XSS) attacks via the siprop parameter in a query action to
wiki/api.php.
