TITLE:
Wordpress Script Insertion and SQL Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA26771

VERIFY ADVISORY:
http://secunia.com/advisories/26771/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
WordPress 2.x
http://secunia.com/product/6745/
WordPress MU 1.x
http://secunia.com/product/14628/

DESCRIPTION:
Some vulnerabilities have been reported in Wordpress, which can be
exploited by malicious users to conduct script insertion attacks and
by malicious people to conduct SQL injection attacks.

1) The "unfiltered_html" privilege feature can be bypassed by adding
a field named "no_filter". This can be exploited by malicious users
without the "unfiltered_html" privilege to e.g. post blog entries
with arbitrary HTML and script code via specially crafted POST
requests.

2) Input passed to certain parameters (e.g. the "post_type" parameter
of the URL passed to the "pingback.extensions.getPingbacks()" XMLRPC
method) is not properly sanitised before being used in SQL queries.
This can be exploited to manipulate SQL queries by injecting
arbitrary SQL code.

The vulnerabilities are reported in Wordpress prior to 2.2.3 and
Wordpress MU prior to 1.2.5a.

SOLUTION:
Update to Wordpress version 2.2.3 or Wordpress MU version 1.2.5a.
