CVE-2024-50690Network attack vector

Firmware disclosure via WebUI hardcoded decryption password

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 decrypt update files. The WiNet-S WebUI embeds the hardcoded password accepted for decrypting encrypted firmware update files, exposing every update's contents. Network access is sufficient and requires no authentication; the established consequence is firmware disclosure, not direct device-code execution.
