Communications interruption via Ethernet controller exhaustion
Published Feb 13, 2024 · Updated Nov 7, 2024
Uncontrolled resource consumption in affected HIMA safety-controller modules allows remote attackers to interrupt communications via Ethernet traffic. Wire-speed traffic at 1 Gbit/s or 100 Mbit/s on one port exhausts Ethernet-controller resources, triggering an automatic reset after the load stops. No authentication or user action is required; all other communications through that Ethernet controller are interrupted until traffic subsides and reset completes.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
