Server-Side Request Forgery in Tapo Cloud MQTT Proxy

Summary

The Tapo Cloud MQTT proxy contains a server-side request forgery (SSRF) vulnerability because it accepts a user-controlled host value without sufficient input validation. An attacker may exploit this vulnerability to cause the Tapo Cloud service to send requests to an attacker-controlled server. Successful exploitation may cause the Tapo Cloud service to send a request to an attacker-controlled server, exposing the internal information and causing potential Distributed Denial-of-Service (DDoS).

Remediation

1. Inventory every TP-Link Systems Inc. Tapo Cloud Service deployment, including staging.
