More information:

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.

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

For the unstable distribution (sid), this problem has been fixed in version 1:1.19.16+dfsg-1.

We recommend that you upgrade your mediawiki packages.
