安全系统：

Cisco IOS 12.3

漏洞报告人：

无

漏洞描述：

测试方法：

无

解决方法：

临时解决方法：

假如您不能马上安装补丁或者升级，NSFOCUS建议您采取以下措施以降低威胁：

* 在路由器上通过访问控制列表(ACL)过滤从未授权地址直接发往路由器本身地址的流量。
  使用访问控制列表可能造成性能影响，您应当根据实际情况谨慎选用合理的访问控制列表。
  您可以参考Cisco提供的下列文档进行设置:

  http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.sHtml#workarounds
  http://www.cisco.com/warp/public/707/racl.html
  http://www.cisco.com/warp/public/707/iacl.html

Cisco 也提供了一个样例ACL, 禁止所有协议类型为53,55,77,103的报文通过路由器:

    access-list 101 deny 53 any any
    access-list 101 deny 55 any any
    access-list 101 deny 77 any any
    access-list 101 deny 103 any any
    !--- insert any other PReviously applied ACL entries here
    !--- you must permit other protocols through to allow normal
    !--- traffic -- previously defined permit lists will work
    !--- or you may use the permit ip any any shown here
    access-list 101 permit ip any any
