Tp-Link: >> Tapo C200 Firmware >> 1.3.9 Security Vulnerabilities
A stack-based buffer overflow vulnerability was identified in the ONVIF SOAP XML Parser in Tapo C200 v3 and C520WS v2.6. When processing XML tags with namespace prefixes, the parser fails to validate the prefix length before copying it to a fixed-size stack buffer. It allowed a crafted SOAP request with an oversized namespace prefix to cause memory corruption in stack.
An unauthenticated attacker on the same local network may exploit this flaw to enable remote code execution with elevated privileges, leading to full compromise of the device.

The HTTPS service on Tapo C200 V3 exposes a connectAP interface without proper authentication. An unauthenticated attacker on the same local network segment can exploit this to modify the device’s Wi-Fi configuration, resulting in loss of connectivity and denial-of-service (DoS).

The HTTPS server on Tapo C200 V3 does not properly validate the Content-Length header, which can lead to an integer overflow. An unauthenticated attacker on the same local network segment can send crafted HTTPS requests to trigger excessive memory allocation, causing the device to crash and resulting in denial-of-service (DoS).
