Arbitrary commands via unvalidated MQTT server certificate
Published Feb 12, 2026 · Updated Feb 12, 2026
Improper certificate validation in affected SolaX Power Pocket WiFi firmware allows man-in-the-middle attackers to issue arbitrary commands. The cloud client opens MQTTS connections to mqtt001.solaxcloud.com on TCP 8883 without validating the server certificate, accepting an attacker-controlled broker as legitimate. Exploitation requires interception or redirection of the cloud connection, such as BGP hijacking or DNS spoofing, and permits inverter control or malicious firmware delivery through broker commands.
