What is CVE-2001-0866?

The Cisco 12000 Series Routers equipped with IOS version 12.0 and using multi-port line cards are vulnerable due to improper handling of outbound Access Control Lists (ACLs). When an input ACL is not configured on all interfaces of a multi-port line card, it can lead to circumvention of intended access controls. This misconfiguration allows remote attackers to exploit the vulnerabilities, potentially gaining unauthorized access to network resources.
