CVE-2025-65856Public exploitNetwork attack vector

Unauthenticated camera access via missing ONVIF checks

Published Dec 22, 2025 · Updated Dec 22, 2025

Authentication bypass in Xiongmai XM530 firmware 5.00.R02.000807D8.10010.346624.S.ONVIF 21.06 allows remote attackers to access video and device data. The ONVIF web service accepts SOAP requests at 31 protected endpoints without validating WS-Security headers, including GetDeviceInformation and GetStreamUri. No credentials or user interaction are required; network-reachable cameras disclose live streams, configuration, user data, and stream credentials and permit PTZ and relay control.
