VERIFY ADVISORY:
http://secunia.com/advisories/12825/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:

SOFTWARE:
MediaWiki 1.x

DESCRIPTION:
Multiple vulnerabilities have been reported in MediaWiki, which can
be exploited by malicious people to conduct script insertion,
cross-site scripting, and SQL injection attacks.

1) Input passed in UnicodeConverter extension and "raw" page view is
not properly sanitised before being used. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site when the malicious user data is viewed.

2) Input passed to "SpecialIpblocklist", "SpecialEmailuser",
"SpecialMaintenance", and "ImagePage" isn't properly sanitised before
being returned to the user. This can be exploited to execute arbitrary
HTML and script code in a user's browser session in context of a
vulnerable site.

3) MediaWiki fails to verify input passed to "SpecialMaintenance"
properly, before it is used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 1.3.5. Other
versions may also be affected.

SOLUTION:
Update to version 1.3.6.
