DescriptionFUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Versions 1.2.11 until 1.3.1 allow an unauthenticated remote attacker to achieve Full Remote Code Execution (RCE) as root. The exploit succeeds even when the platform is configured in its most secure state (Secure Mode Enabled and Node-RED Secure Auth Enabled). Version 1.3.1 fixes the issue.
