BUG MIGRATED FROM SOURCEFORGE
http://sourceforge.net/tracker/index.php?func=detail&aid=842921&group_id=34373&atid=411192
Originally submitted by Brion Vibber (vibber)<a href="/help/icon_legend.php?context=user_wantsdonations&amp;user_id=446709&amp;return_to=%2F"><IMG src="http://images.sourceforge.net/images/icons/donate.png" alt="Accepting Donations" border="0" width="16" height="16"></a>  2003-11-16 00:29


Most form-handling code in the wiki doesn't actually check 
whether its stuff came via a GET or POST request. For the 
most part this isn't a big deal, but for admin actions that 
have confirmation screens, it's probably not a good idea.

It's possible for instance to craft a URL that will delete a 
page or ban an IP address and trick a sysop into loading it 
(possibly disguised as an inline image, hidden iframe or 
other secondary URL) and performing the action.

It's more difficult to fake a POST request, although still 
possible; checking the referrer header to avoid constructed 
forms on other sites (potentially autosubmitted via 
javascript) might be a step to counter this.
Comment 1 Brion Vibber 2005-02-25 05:59:04 UTC
Most POSTable forms now check $wgRequest->wasPosted(), and admin & editing forms protect 
against off-site form submissions with a session-based token key.

Resolving as FIXED.
