Invision Power Board ipsclass.php脚本远程SQL注入漏洞

发布日期：2006-07-18
更新日期：2006-07-19

受影响系统：

Invision PS IPB 2.1.x

不受影响系统：

Invision PS IPB 2.1.7

描述：

BUGTRAQ  ID: 18984

Invision Power Board是一个非常流行的PHP论坛程序。

Invision Power Board对用户请求数据的处理存在输入验证漏洞，远程攻击者可能利用此漏洞对服务器执行SQL注入攻击，非法操作数据库。

在Invision Power Board的ipsclass.php脚本中由于没有正确的验证对CLIENT_IP HTTP头字段的输入数据，因此远程攻击者可以利用SQL注入攻击执行任意SQL代码。
