CVE-2004-0469: Buffer overflow in the ISAKMP functionality for Check Point VPN-1 and FireWall-1 NG products, before VPN-1/...

Security readout for executives and security teams

CVE-2004-0469 is a buffer overflow in Check Point VPN and firewall products during VPN tunnel negotiation. If an affected gateway or client is still in use, a remote attacker may be able to execute code. This is old, but legacy perimeter VPN systems can remain exposed for years. Exposure is most likely on legacy Check Point VPN-1 or FireWall-1 NG deployments handling ISAKMP/IKE VPN negotiation, especially internet-facing VPN gateways. The bundle does not provide CPEs or a complete affected-version matrix. Treat as high priority only if these legacy Check Point products remain deployed. The business issue is potential remote code execution on VPN or firewall infrastructure, but urgency depends on whether affected versions are still present. Mitigation focus: Upgrade VPN-1/FireWall-1 R55 to HFA-03 or later vendor-fixed level.; Upgrade R54 to HFA-410 or NG FP3 to HFA-325 where applicable.; Upgrade VPN-1 SecuRemote/SecureClient to R56 or later vendor-fixed level..
