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.
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.

If a cross-domain policy file includes domains that should not be trusted, such as when using wildcards under a high-level domain, then the application could be attacked by these untrusted domains. In many cases, the attack can be launched without the victim even being aware of it.
