description

OpENer v2.3 at commit 76b95cf is affected by an out-of-bounds read in the server-side EtherNet/IP ForwardOpen connection-path parser. A remote attacker may cause a denial of service when they can send traffic that reaches the affected parser.

mitigation

Restrict EtherNet/IP access to trusted hosts and networks, and isolate affected OpENer services from untrusted networks. Update to a vendor-provided corrected release when one is available; the evidence does not identify a fixed version.
