CVE-2024-23765Public exploitNetwork attack vector

Network-service outage via port 7412 resource exhaustion

Published Jun 26, 2024 · Updated Nov 14, 2024

Denial of service in HMS Anybus X-Gateway AB7832-F firmware 3.29.01 allows remote attackers to halt network services via UDP requests. The mainboard's daughter-card API creates the port 7412 service but fails to handle malformed packets resiliently, exhausting daughter-card resources. Network reachability is sufficient; successful exploitation stops gateway traffic until power is physically disconnected and restored.
