http://secunia.com/advisories/15758/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data

WHERE:
>From remote

SOFTWARE:
MercuryBoard 1.x
http://secunia.com/product/4560/

DESCRIPTION:
4yka has reported a vulnerability in MercuryBoard, which can be
exploited by malicious people to conduct SQL injection attacks.

Input passed to the "User-Agent" HTTP header in "index.php" isn't
properly sanitised before being used in a SQL query. This can
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been reported in version 1.1.4. Other versions
may also be affected.

SOLUTION:
Set "magic_quotes_gpc" to "On".

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