ABB disclosed three ICS/OT vulnerability clusters this week affecting energy management, edge computing, and substation automation platforms across critical infrastructure sectors. Two authentication bypass flaws (OPTIMAX and Edgenius) allow unauthenticated access or code execution, with OPTIMAX versions 6.1 and 6.2 permanently unpatched. A third cluster targets the IEC 61850 MMS communication stack in System 800xA and Symphony Plus, enabling denial-of-service against industrial process automation. Organizations in energy, utilities, and critical manufacturing running these platforms must act this week.
