CVE-2014-2108: Cisco IOS 12.2 and 15.0 through 15.3 and IOS XE 3.2 through 3.7 before 3.7.5S and 3.8 through 3.10 before 3...

Security readout for executives and security teams

This flaw can let a remote attacker crash and reload affected Cisco IOS or IOS XE devices by sending a malformed IKEv2 packet. The business impact is service disruption, especially for VPN gateways or edge routers using IKEv2. Exposure is most likely on Cisco routers or gateways running affected IOS or IOS XE releases with IKEv2 reachable from untrusted networks. The bundle does not identify specific device models or configurations beyond software and IKEv2. Prioritize remediation for internet-facing VPN or edge devices because reloads can interrupt connectivity. Treat internal-only or non-IKEv2 devices as lower urgency after confirming exposure. No active exploitation is evidenced in the provided sources. Mitigation focus: Review Cisco advisory cisco-sa-20140326-ikev2 for affected trains and fixed releases.; Upgrade IOS XE before 3.7.5S or before 3.10.1S to fixed versions.; For IOS 12.2 or 15.0-15.3, confirm vendor-recommended fixed rebuilds..
