DESCRIPTION:
rgod has discovered a vulnerability in PHP121 Instant Messenger,
which can be exploited by malicious people to conduct SQL injection
attacks.

Input passed in cookies to php121login.php is not properly sanitised
before being used in SQL queries. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.

This can reportedly further be exploited to include arbitrary local
files on a windows system.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been confirmed in version 1.4. Other versions
may also be affected.

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