Lifecycle Timeline
2DescriptionGitHub Advisory
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. From 1.2.8 through version 1.2.10, an authorization bypass vulnerability in the FUXA allows an unauthenticated, remote attacker to create and modify arbitrary schedulers, exposing connected ICS/SCADA environments to follow-on actions. This has been patched in FUXA version 1.2.11.
Executive ViewAI
A critical vulnerability (CVSS 9.1) in FUXA web-based SCADA/HMI software could allow unauthorized attackers to compromise industrial process visualization systems and potentially disrupt operational technology environments. Organizations running FUXA are at immediate risk of system compromise, data theft, and operational disruption until patching is completed.
Apply vendor patch.
