UMAS (Unified Messaging Application Services) is a proprietary Schneider Electric (SE) protocol used to configure and monitor Schneider Electric PLCs. Schneider Electric controllers that use UMAS include Modicon M580 CPU (part numbers BMEP* and BMEH*) and Modicon M340 CPU (part numbers BMXP34*). Controllers are configured and programmed using engineering software – EcoStruxure™ Control Expert (Unity Pro), EcoStruxure™ Process Expert, etc. In 2020, CVE-2020-28212, a vulnerability affecting ...
