CVE-2020-28999Network attack vector

Camera takeover via hard-coded streaming-service credentials

Published Jan 26, 2021 · Updated Aug 4, 2024

Authentication bypass in Geeni GNC-CW013 doorbell firmware 1.8.1 allows remote attackers to take full control of the camera. The Apexis streaming service loads a static username and password compiled into libhipcam.so, granting the same high-privileged account on affected devices. Network reachability to the streaming service and possession of the embedded credentials are required; successful authentication permits complete camera control.
