CVE-2025-41279Network attack vector

Authenticated OS command execution via Administration WebUI

Published May 29, 2026 · Updated May 29, 2026

OS command injection in WF-500 RX Host 7.9.1.0 R2502171040 and earlier allows remote authenticated users to execute OS commands via the WebUI. The advisory says the Administration WebUI fails to neutralize special elements before an operating system command is formed, but it does not identify the request, parameter, or code path. High-privilege authenticated access is required; successful exploitation gives command execution on the RX Host without user interaction.
