The LAN-to-LAN IPSEC capability for Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.4, allows remote attackers to cause a denial of service via an incoming LAN-to-LAN connection with an existing security association with another device on the remote network, which causes the concentrator to remove the previous connection.

Security readout for executives and security teams

This is a denial-of-service issue in Cisco VPN 3000 Concentrator LAN-to-LAN IPsec. A remote connection scenario can cause the concentrator to remove an existing VPN connection, disrupting site-to-site connectivity. The sources do not indicate active exploitation or provide a CVSS score. Exposure is likely limited to legacy Cisco VPN 3000 Concentrator deployments using LAN-to-LAN IPsec. Organizations with retired, replaced, or non-IPsec site-to-site VPN infrastructure are unlikely to be affected. Prioritize this where legacy Cisco VPN 3000 devices still support business-critical site-to-site connectivity. The impact is availability disruption, not confirmed data compromise, but an outage could affect remote offices or partner links. Mitigation focus: Identify any Cisco VPN 3000 Concentrator appliances still in service.; Check whether LAN-to-LAN IPsec is enabled on those devices.; Review Cisco advisory guidance for fixed software or replacement options..
