What is CVE-2021-44403?

A denial of service vulnerability has been identified in the JSON command parser of the Reolink RLC-410W camera. An adversary can craft a malicious HTTP request that, when processed, can trigger a reboot of the device. This may lead to interruptions in service and pose risks to device availability. The vulnerability arises from improper handling of the 'GetPtzTattern' parameter, which is expected to be an object. It highlights the importance of securing IoT devices against malformed inputs to prevent service disruptions.
