Description

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.
