CVE-2002-2208 is a high-severity vulnerability affecting the Extended Interior Gateway Routing Protocol (EIGRP) implemented in certain Cisco IOS versions and other products. This vulnerability allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, resulting in an ARP storm on the local network.

How do I know if I'm affected?

If you're using Cisco IOS versions 11.3, 12.0, 12.1, or 12.2, your system might be at risk of the vulnerability. This issue affects the Extended Interior Gateway Routing Protocol (EIGRP) and can cause a denial of service (flood) on your local network. To know if you're affected, check your Cisco IOS version and monitor your network for any unusual ARP storms or flooding caused by spoofed EIGRP neighbor announcements.

What should I do if I'm affected?

If you're affected by the vulnerability, take these steps to protect your network. First, block access to core infrastructure using access control lists (ACLs). Then, configure anti-spoofing measures like Unicast Reverse Path Forwarding (uRPF) or ACLs. Next, deploy 802.1x-based port security. Then, use static defined EIGRP neighbors. Finally, enable MD5 Neighbor Authentication.
