Exploitation Summary

EIP tracks 1 public exploit for CVE-2022-43704. PoCs published by 9lyph.

AI-analyzed exploit summary This repository contains a Python-based PoC for CVE-2022-43704, which exploits an authentication bypass via capture-replay in the Sinilink XY-WFTX WiFi Remote Thermostat. The exploit leverages UDP communication to retrieve device info and send malicious payloads to control the relay without authentication.

Description

The Sinilink XY-WFT1 WiFi Remote Thermostat, running firmware 1.3.6, allows an attacker to bypass the intended requirement to communicate using MQTT. It is possible to replay Sinilink aka SINILINK521 protocol (udp/1024) commands interfacing directly with the target device. This, in turn, allows for an attack to control the onboard relay without requiring authentication via the mobile application. This might result in an unacceptable temperature within the target device's physical environment.
