CVE-2022-4240Network attack vector

Network-resource disclosure via unauthenticated API

Published May 30, 2023 · Updated Jan 9, 2025

Missing authentication in Honeywell OneWireless Wireless Device Manager 322.1 allows remote attackers to bypass critical API access controls. The vendor identifies an unauthenticated API that returns information about network resources but has not disclosed the endpoint or omitted authentication operation. Network access to the appliance is sufficient; the disclosed result is resource-information exposure, while Honeywell's vector records limited integrity and availability effects.
