Synopsis

The remote Debian host is missing a security-related update.

Description

Omer Iqbal discovered that MediaWiki, a wiki engine, parses invalid usernames on Special:PasswordReset as wikitext when $wgRawHtml is enabled. On such wikis this allows an unauthenticated attacker to insert malicious JavaScript, a cross site scripting attack.

Solution

Upgrade the mediawiki packages.

For the stable distribution (wheezy), this problem has been fixed in version 1:1.19.16+dfsg-0+deb7u1.
