CVE-2024-50692Network attack vector

Unauthorized inverter control via hardcoded MQTT credentials

Published Jan 24, 2025 · Updated Feb 6, 2025

Hardcoded credentials in Sungrow WiNet-S firmware WINET-SV200.001.00.P027 and earlier allow remote attackers to control inverters. The module embeds reusable MQTT credentials and does not authenticate the MQTT broker with TLS, enabling device or broker impersonation. Network access to MQTT is required; successful abuse permits arbitrary inverter commands and interception or modification of broker traffic.
