VERIFY ADVISORY:
http://secunia.com/advisories/24689/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, Exposure of sensitive information, System
access

WHERE:
>From remote

SOFTWARE:
MyBB (formerly MyBulletinBoard) 1.x
http://secunia.com/product/4479/

DESCRIPTION:
DarkFig has reported a vulnerability in MyBB, which can be exploited
by malicious people to conduct SQL injection attacks and compromise a
vulnerable system.

Input passed in the "Client-IP" HTTP header to index.php is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation allows e.g. retrieving administrator IP
addresses and SIDs, which can be used to log in as administrator and
upload PHP files, which can then be exploited to execute arbitrary
code.

The vulnerability is related to:
SA21070

The vulnerability is reported in all 1.2.x versions prior to 1.2.4.
Other versions may also be affected.

SOLUTION:
Update to version 1.2.4.

Use another product.
