Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Product-specific: Opcenter Execution Foundation V2407, Opcenter Quality V2312, SIMATIC PCS neo V4.1, SINEC NMS V2.0 SP1, TIA Portal V17 Update 8, or TIA Portal V18 Update 3

  1. 1. Identify the specific Siemens product from the affected list: Opcenter Execution Foundation, Opcenter Quality, SIMATIC PCS neo, SINEC NMS, or Totally Integrated Automation Portal (TIA Portal)
  2. 2. Determine the current installed version of the affected product
  3. 3. For Opcenter Execution Foundation: upgrade to version V2407 or later
  4. 4. For Opcenter Quality: upgrade to version V2312 or later
  5. 5. For SIMATIC PCS neo: upgrade to version V4.1 or later
  6. 6. For SINEC NMS: upgrade to version V2.0 SP1 or later
