GravityBoardX(GBX)1.1存在SQL注入漏洞。这使得远程攻击者可以借助于登陆字段执行任意SQL命令和绕过认证。

source: http://www.securityfocus.com/bid/14497/info

Gravity Board X (GBX) 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.

Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation. 

The following demonstrates login credentials sufficient to exploit this vulnerability:
login: ' or isnull(1/0) /*
password: whatever
