Technical description
TP-Link Tapo C200 v5 contains a stack-based buffer overflow flaw in RTSP authentication handling due to improper validation of Authorization header field lengths, which can be triggered by a crafted authentication request.
Successful exploitation causes the affected RTSP core service process to crash and triggers an automatic system reboot, resulting in a denial of service (DoS) condition. This prevents legitimate users from accessing the camera’s live video stream or management interface until the service restarts.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
