CVE-2025-29756

SunGrow's back end users system iSolarCloud https://isolarcloud.com uses an MQTT service to transport data from the user's connected devices to the user's web browser. The MQTT server however did not have sufficient restrictions in place to limit the topics that a user could subscribe to. While the data that is transmitted through the MQTT server is encrypted and the credentials for the MQTT server are obtained though an API call, the credentials could be used to subscribe to any topic and the encryption key can be used to decrypt all messages received. An attack with an account on iSolarCloud.com could extract MQTT credentials and the decryption key from the browser and then use an external program to subscribe to the topic '#' and thus recieve all messages from all connected devices.

Summary		(es) El sistema de usuarios back-end de SunGrow, iSolarCloud (https://isolarcloud.com), utiliza un servicio MQTT para transportar datos desde los dispositivos conectados del usuario a su navegador web. Sin embargo, el servidor MQTT no tenía suficientes restricciones para limitar los temas a los que un usuario podía suscribirse. Si bien los datos que se transmiten a través del servidor MQTT están cifrados y las credenciales se obtienen mediante una llamada a la API, estas credenciales pueden usarse para suscribirse a cualquier tema y la clave de cifrado puede usarse para descifrar todos los mensajes recibidos. Un ataque con una cuenta en iSolarCloud.com podría extraer las credenciales MQTT y la clave de descifrado del navegador y, a continuación, usar un programa externo para suscribirse al tema '#' y, por lo tanto, recibir todos los mensajes de todos los dispositivos conectados.
