Cisco Access Control List Fragment Keyword Ignored Vulnerability
IOS is the Cisco Internet Operating System, distributed with and used on various Cisco network hardware. A vulnerability in IOS on the 12000 series Cisco routers could make it possible for a remote user to send unauthorized traffic to a protected network. IOS does not filter packet fragments, even when the 'fragment' keyword is included in an ACL rule. This vulnerability may result in attackers or users bypassing security policy. |
