[原文]Snapgear Lite+ firewall 1.5.3 allows remote attackers to cause a denial of service (IPSEC crash) via a zero length packet to UDP port 500.


[CNNVD]Snapgear Lite+ 防火墙IPSEC实现拒绝服务攻击漏洞(CNNVD-200206-045)

        
        Snapgear Lite+是一款集成防火墙、路由和VPN支持的设备。
        Snapgear Lite+ 防火墙在处理IPSEC实现时存在问题,可导致远程攻击者进行拒绝服务攻击。
        如果Snapgear Lite+防火墙IPSEC功能使能的情况下,攻击者可以通过向防火墙发送0字节数据长度的UDP包,导致IPSEC实现崩溃,使VPN通道产生拒绝服务。

- 漏洞讨论

Snapgear Lite+ is a device with integrated firewall, routing, and VPN support.

Sending a 0 length UDP packet through the firewall when IPSEC is enabled will cause the IPSEC implementation to fail. This may result in a denial of VPN/tunnel service.

- 漏洞利用

There is no exploit code required.

- 解决方案

The vendor has released a firmware upgrade.
