CVE-2000-0482: Check Point Firewall-1 allows remote attackers to cause a denial of service by sending a large number of ma...

Security readout for executives and security teams

A flaw in Check Point Firewall-1 lets a remote attacker crash or slow the firewall by flooding it with malformed fragmented IP packets. Because the firewall protects the perimeter of a network, an outage here can knock legitimate business traffic offline until service is restored. This is a denial-of-service issue, not a data-theft or takeover flaw. Exposure is limited to legacy Check Point Firewall-1 deployments reachable from untrusted networks. The vulnerability dates to 2000, and any modern, patched Check Point gateway should not be affected. Environments still running unsupported Firewall-1 versions at the perimeter face the greatest risk of outage. Low priority for modern environments, but treat as urgent if any Firewall-1 device from that era is still perimeter-facing. A successful attack does not steal data, but it can take the firewall — and therefore internet-facing business services — offline until traffic subsides or the device is restarted. Mitigation focus: Confirm no unsupported Check Point Firewall-1 instances remain in service; upgrade to a currently supported gateway version.; Review Check Point's advisory list for the IP Fragmentation entry and apply the referenced vendor guidance.; Restrict inbound access to firewall management and service interfaces to trusted networks..
