Title
Unauthenticated Access to connectAP API Endpoint on Tapo C100, C200 & C425
Summary
The HTTPS service on Tapo C200 v3, v5, C425 v1.2 and C100 v5  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).
