7.5 · HIGHOverview
CVE-2005-4437 is a high-severity vulnerability affecting extended_interior_gateway_routing_protocol extended_interior_gateway_routing_protocol. It was published on December 21, 2005 and has a CVSS 2.0 base score of 7.5 (HIGH).
This vulnerability has a CVSS 2.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
MD5 Neighbor Authentication in Extended Interior Gateway Routing Protocol (EIGRP) 1.2, as implemented in Cisco IOS 11.3 and later, does not include the Message Authentication Code (MAC) in the checksum, which allows remote attackers to sniff message hashes and (1) replay EIGRP HELLO messages or (2) cause a denial of service by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network.
