CVE-2024-50698Network attack vector

Remote code execution via MQTT message overflow

Published Jan 24, 2025 · Updated Sep 15, 2025

Heap-based buffer overflow in Sungrow WiNet-S WINET-SV200.001.00.P027 and earlier allows remote attackers to execute code via MQTT messages. The MQTT-processing path applies inadequate bounds checks to message content, allowing it to overrun a heap buffer; Sungrow has not named the affected function. Unauthenticated network access is sufficient, and exploitation can execute code or interrupt the device service.
