CVE-2025-15573: Improper certificate validation vulnerability

The affected devices do not validate the server certificate when connecting to the SolaX Cloud MQTTS server hosted in the Alibaba Cloud (mqtt001.solaxcloud.com, TCP 8883). This allows attackers in a man-in-the-middle position to act as the legitimate MQTT server and issue arbitrary commands to devices.
