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
Siemens SINUMERIK Integrate Operate Clients between 2.0.3.00.016 (including) and 2.0.6 (excluding) and between 3.0.4.00.032 (including) and 3.0.6 (excluding) contain a vulnerability that could allow an attacker to read and manipulate data in TLS sessions while performing a man-in-the-middle (MITM) attack.

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 · high confidence

This is a TLS man-in-the-middle vulnerability in Siemens SINUMERIK Integrate Operate Clients. The vulnerability allows an attacker to read and manipulate data in encrypted TLS sessions, indicating improper certificate validation or weak TLS implementation in the affected client software.

MitigationUpdate SINUMERIK Integrate Operate Clients to version 2.0.6 or 3.0.6 or higher to obtain the patched TLS implementation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Sinumerik Integrate software
    Locate Siemens Sinumerik Integrate Operate Client or Sinumerik Integrate Access Mymachine/ethernet installations on the system. Check program directories, installed programs list, or Siemens software inventory for these products.
    Affected if Any Sinumerik Integrate Operate Client or Access Mymachine/ethernet software is found on the system
  2. Determine the installed version of Sinumerik Integrate Operate Client
    Using system inventory tools or Siemens software management utilities, retrieve the exact version number of the Sinumerik Integrate Operate Client installation. Compare against known affected versions 2.0.3.00.016 and 3.0.4.00.032.
    Affected if The installed version is exactly 2.0.3.00.016 or exactly 3.0.4.00.032
  3. Determine the installed version of Sinumerik Operate
    Using system inventory tools or Siemens software management utilities, retrieve the exact version number of the Sinumerik Operate installation. Compare against known affected versions 4.5 and 4.7.
    Affected if The installed version is exactly 4.5 or exactly 4.7
  4. Determine the installed version of Sinumerik Integrate Access Mymachine/ethernet
    Using system inventory tools or Siemens software management utilities, retrieve the version of Sinumerik Integrate Access Mymachine/ethernet. Note that all versions of this product are affected.
    Affected if Any version of Sinumerik Integrate Access Mymachine/ethernet is installed
  5. Verify TLS client functionality is in use
    Check if the Sinumerik Integrate client is configured to establish outbound TLS connections to upstream servers. Review client configuration files or network connection settings for active TLS client profiles.
    Affected if TLS client connections are configured and active

The environment is affected if any Sinumerik Integrate Operate Client version 2.0.3.00.016 or 3.0.4.00.032, Sinumerik Operate version 4.5 or 4.7, or any version of Sinumerik Integrate Access Mymachine/ethernet is installed and TLS client functionality is enabled.
