[原文]Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862.


[CNNVD]Cisco IOS switching(DFS)权限许可和访问控制(CNNVD-199912-195)

        Cisco IOS 11.1至11.3的distributed fast switching(DFS)存在漏洞,当路由转换器使用子接口从DFS的输入接口流通至输出接口时(如Cisco bug CSCdk43862描述),远程攻击者可以绕过指定访问控制列表。

8805
Cisco IOS DFS Subinterface Access Control Bypass
Remote / Network Access Infrastructure
Loss of Integrity

- 漏洞描述

Cisco IOS contains a flaw that may allow a malicious user to send packets or fragments of packets to a subinterface even when an access control list prohibits such behaviour. The issue is triggered when distributed fast switching is enabled. It is possible that the flaw may allow traffic which ought to be prohibited by ACL to transit from a DFS-enabled input interface to an output interface with a logical subinterface, thereby resulting in a loss of integrity.
