CVE-2021-44369Network attack vector

Camera reboot via malformed SetNtp JSON

Published Jan 28, 2022 · Updated Apr 15, 2025

Denial of service in Reolink RLC-410W firmware 3.0.0.136_20121102 allows remote attackers to reboot the camera via an HTTP request. The cgiserver.cgi JSON command parser mishandles a SetNtp parameter that is not an object, triggering a reboot. An attacker needs network access to the camera's HTTP interface; successful requests interrupt service until the device restarts.
