IBWd Guestbook 1.0 - 'index.php' SQL Injection

                source: http://www.securityfocus.com/bid/18256/info

iBWd Guestbook is prone to an SQL-injection vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input before using it in an SQL query. 

A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.
