CVE-2000-0882: Intel Express 500 series switches allow a remote attacker to cause a denial of service via a malformed ICMP...

Security readout for executives and security teams

A very old flaw (from 2000) in Intel Express 500 series network switches lets an attacker on the network send a specially malformed ping-style packet that crashes the switch's processor, knocking it offline. It is a denial-of-service issue only, not a data breach, and it affects hardware that is well beyond its supported life. Exposure is limited to organizations still running Intel Express 500 series switches with their management or in-band interfaces reachable by untrusted networks. Modern environments have almost certainly retired this hardware, so real-world exposure today is expected to be minimal. Low priority. This is a legacy 2000-era denial-of-service issue in end-of-life switch hardware. Address only if Intel Express 500 series switches remain in use anywhere in the environment; otherwise close as informational. Mitigation focus: Inventory the network for any surviving Intel Express 500 series switches and plan replacement with supported hardware.; Restrict ICMP and management access to switch interfaces using ACLs on upstream routers or firewalls.; Segment legacy switches onto isolated management VLANs unreachable from user or internet-facing networks..
