"According to its version number, the instance of MediaWiki running on
the remote host is affected by a cross-site request forgery
vulnerability.

A flaw exists with Special:ChangePassword within the
includes/specials/SpecialChangePassword.php script where HTTP requests
do not require explicit confirmation, a unique token, and/or multiple
steps performing sensitive actions. This allows a context-dependent
attacker to reset a user's password.

Nessus has not tested for this issue but has instead relied on the
application's self-reported version number.");
