A vulnerability has been identified in Opcenter Execution Foundation (All versions < V2407), Opcenter Quality (All versions < V2312), SIMATIC PCS neo (All versions < V4.1), SINEC NMS (All versions < V2.0 SP1), Totally Integrated Automation Portal (TIA Portal) V14 (All versions), Totally Integrated Automation Portal (TIA Portal) V15.1 (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions < V17 Update 8), Totally Integrated Automation Portal (TIA Portal) V18 (All versions < V18 Update 3). When accessing the UMC Web-UI from affected products, UMC uses an overly permissive CORS policy. This could allow an attacker to trick a legitimate user to trigger unwanted behavior.
