CVE-2024-50688Network attack vector

Telemetry disclosure via shared hardcoded MQTT credentials

Published Feb 26, 2025 · Updated Mar 4, 2025

Hard-coded credentials in Sungrow iSolarCloud Android 2.1.6.20241017 and earlier allow remote attackers to access MQTT telemetry. The application embeds the same MQTT credentials used by the cloud to exchange device telemetry, exposing a shared broker identity in every affected copy. No account privileges or user interaction are required; the established impact is limited to unauthorized access to or manipulation of device telemetry.
