VLAN boundary bypass via faulty origin verification
Published Feb 13, 2024 · Updated May 8, 2025
Origin validation errors in HIMA safety-controller firmware allow remote attackers to send ICMP ping requests across VLAN boundaries. The origin-verification logic accepts a ping received on one network and forwards it through a port assigned to a different VLAN. Exploitation requires adjacent network access but no authentication; the reported consequence is limited to crossing segmentation and disclosing host reachability.

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.
