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). The affected application contains an out of bounds write past the end of an allocated buffer when handling specific requests on port 4002/tcp. This could allow an attacker to crash the application. The corresponding service is auto-restarted after the crash.

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.

dbcve analysis
How this class of weakness works · CWE-120

A fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

General guidance for the classic buffer overflow class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

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

  1. 1. Identify the specific Siemens product from the affected list running in your environment (Opcenter Quality, SIMATIC PCS neo, Sinumerik Integrate Runmyhmi/automotive, TIA Portal, or others)
  2. 2. For Opcenter Execution Foundation: upgrade to V2407 or later
  3. 3. For Opcenter Quality: upgrade to V2312 or later
  4. 4. For SIMATIC PCS neo: upgrade to V4.1 or later
  5. 5. For SINEC NMS: upgrade to V2.0 SP1 or later
  6. 6. For Totally Integrated Automation Portal V17: upgrade to V17 Update 8 or later
  7. 7. For Totally Integrated Automation Portal V18: upgrade to V18 Update 3 or later
  8. 8. After upgrade, verify the service on port 4002/tcp is functioning correctly
Caveat Some product lines (TIA Portal V14, V15.1, V16, Opcenter Quality all versions, Sinumerik Integrate Runmyhmi/automotive) lack documented fixed versions in the advisory - may require contacting Siemens for specific patch guidance
