Executive Summary

CVE-2026-8714 is a denial-of-service vulnerability in the RTSP server component of the TP-Link Tapo C520WS v2 camera. It occurs because the server improperly handles syntactically invalid or malformed input, which triggers a processing error. This error causes the RTSP service to become unresponsive, effectively disrupting the camera's functionality.

Detection Guidance

This vulnerability causes the RTSP service on the TP-Link Tapo C520WS v2 camera to become unresponsive when it processes syntactically invalid input. Detection can involve monitoring the RTSP service for non-responsiveness or crashes after receiving malformed RTSP requests.

A practical approach to detect this vulnerability is to send crafted malformed RTSP requests to the camera's RTSP server and observe if the service becomes unresponsive, indicating a denial-of-service condition.

Example commands to test the RTSP service might include using tools like curl or netcat to send malformed RTSP requests. For instance:

• Using netcat (nc) to send a malformed RTSP request: echo -e "OPTIONS rtsp://camera-ip:554 RTSP/1.0\r\nCSeq: 1\r\nMalformedHeader\r\n\r\n" | nc camera-ip 554
• Using curl to send an RTSP OPTIONS request (though curl has limited RTSP support): curl -v rtsp://camera-ip:554

If the RTSP service stops responding after such tests, it indicates the presence of the vulnerability.

Note: Always perform such testing in a controlled environment and with permission, as it may disrupt device functionality.
