CVE-2002-2208: Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other...

Security readout for executives and security teams

This is an old Cisco EIGRP denial-of-service issue. Attackers could send many spoofed EIGRP neighbor announcements, triggering an ARP storm that floods the local network. The main business risk is loss of availability on legacy routing segments, not data theft. Exposure is most likely in environments still running EIGRP on legacy Cisco IOS 11.3 through 12.2. The affected list in the bundle is incomplete, so confirm against Cisco’s advisory and actual router inventory. Prioritize if the business still depends on EIGRP in legacy Cisco networks. The issue can disrupt network availability, but the provided evidence does not support a current widespread exploitation claim. Mitigation focus: Inventory routers running EIGRP and identify Cisco IOS 11.3 through 12.2 systems.; Review Cisco’s advisory for vendor-confirmed fixes or configuration guidance.; Upgrade or retire affected legacy routing platforms where vendor guidance supports it..
