DESCRIPTION:
D3vil-0x1 has discovered a vulnerability in MyBB, which can be
exploited by malicious people to conduct SQL injection attacks.

Input passed to the "comma" parameter in misc.php via cookies is not
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 1.0.4. Other versions
may also be affected.

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