Technical details
The ONVIF service endpoints in firmware 3.3.2.4_build_2024-12-26 lack authentication checks on management requests, enabling unauthenticated network access to privileged functions. An attacker with network-level access can directly invoke these endpoints to modify device settings, execute commands, or extract sensitive data. No patch is available; Anjvision has not engaged with CISA on remediation.
