CVE-2004-0710: IP Security VPN Services Module (VPNSM) in Cisco Catalyst 6500 Series Switch and the Cisco 7600 Series Inte...

Security readout for executives and security teams

This affects older Cisco Catalyst 6500 switches and Cisco 7600 routers using the IP Security VPN Services Module. A malformed IKE packet could crash and reload the device, causing a denial of service. Business urgency depends on whether these legacy platforms still terminate VPN or IKE traffic in production. Exposure is likely limited to environments still operating Cisco Catalyst 6500 or Cisco 7600 devices with VPNSM and affected IOS releases, especially where IKE traffic can reach the module. Modern environments without these legacy modules are unlikely to be affected. Prioritize if these legacy Cisco platforms still support production VPN or edge connectivity. The impact is availability, not data theft, but a crash and reload on core infrastructure can cause meaningful outage risk. Mitigation focus: Inventory Catalyst 6500 and Cisco 7600 devices for VPNSM modules.; Check IOS versions against the affected pre-fixed releases listed by Cisco.; Upgrade applicable IOS trains to Cisco fixed versions named in the advisory..
