SECUNIA ADVISORY ID:
SA25165

VERIFY ADVISORY:
http://secunia.com/advisories/25165/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data

WHERE:
>From remote

SOFTWARE:
Nuked-Klan 1.x
http://secunia.com/product/1015/

DESCRIPTION:
DarkFig has discovered a vulnerability in Nuked-Klan, which can be
exploited by malicious people to conduct SQL injection attacks.

Input passed in the "X-Forwarded-For" HTTP header in index.php and
potentially other files 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 administrator access. Note that this
further can be exploited to execute arbitrary PHP code.

The vulnerability is confirmed in version 1.7.6. Other versions may
also be vulnerable.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
