CVE-2020-29000Network attack vector

Device takeover via crafted RTSP message

Published Jan 26, 2021 · Updated Aug 4, 2024

Remote code execution in the RTSP service on Geeni GNC-CW013 doorbell 1.8.1 allows remote authenticated users to take control via a crafted message. Published sources do not identify the RTSP handler or explain how the crafted message causes the service to deliver a Telnet session. Exploitation requires control of the device's DNS resolution and access to a high-privileged account, after which the attacker obtains a Telnet session and camera-system control.
