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 Tecnomatix Plant Simulation (All versions < V2201.0006). The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted SPP files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-20308, ZDI-CAN-20345)

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

Tecnomatix Plant Simulation contains an out-of-bounds read vulnerability when parsing specially crafted SPP files. The vulnerability occurs in the file parsing logic, reading past the end of an allocated memory structure. Successful exploitation allows arbitrary code execution in the context of the current process.

MitigationUpdate Tecnomatix Plant Simulation to version V2201.0006 or later. Until patched, exercise caution with SPP files from untrusted sources.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Verify Tecnomatix Plant Simulation is installed
    Check for the presence of the Tecnomatix Plant Simulation application in the system program directory or Start menu, typically under Siemens Tecnomatix or a similar installation folder.
    Affected if The application is found on the system
  2. Locate the installed version information
    Right-click the Plant Simulation executable or access Help > About in the application menu to view the exact version number. Alternatively, check the program files directory for version details.
    Affected if No version information can be retrieved or the application is not found
  3. Compare installed version to affected range
    Take the installed version (e.g., V2201.0005 or earlier) and compare it numerically against 2201.0006. Versions below 2201.0006 are affected.
    Affected if Installed version is less than 2201.0006 (e.g., 2201.0005, V16, earlier releases)
  4. Confirm SPP file handling capability
    Open Plant Simulation and verify if the application can import or open SPP files through File > Open or drag-and-drop functionality.
    Affected if The SPP file import feature is present and accessible in the installed version

The environment is affected if Tecnomatix Plant Simulation is installed with a version lower than 2201.0006 and the SPP file parsing feature is available.

Upgrade available Upgrade to 2201.0006 or later
Fixed in 2201.0006
Interim mitigation

Update Tecnomatix Plant Simulation to version V2201.0006 or later. Until patched, exercise caution with SPP files from untrusted sources.

Recommended fix High confidence

V2201.0006 or later

  1. 1. Identify the current installed version of Tecnomatix Plant Simulation by opening the application and navigating to Help > About, or checking in the Windows Programs and Features list.
  2. 2. Confirm the installed version is below V2201.0006 (versions such as V2201.0005, V16, V15, etc. are affected).
  3. 3. Back up all critical Plant Simulation projects, libraries, and custom configurations before proceeding with the upgrade.
  4. 4. Obtain the fixed version V2201.0006 (or a later fixed release) from the official Siemens support portal at cert-portal.siemens.com or the Siemens Digital Industries Software download center.
  5. 5. Uninstall the current version of Tecnomatix Plant Simulation through Windows Control Panel > Programs and Features, or proceed with an in-place upgrade if supported by the installer.
  6. 6. Install the downloaded V2201.0006 or later version following the Siemens installation wizard prompts.
  7. 7. After installation, verify the version by checking Help > About to confirm V2201.0006 or higher is installed.
  8. 8. Test that existing SPP files can be opened and parsed correctly in the upgraded application.
Caveat Review Siemens release notes for V2201.0006 to check for any changes to SPP file handling, API behavior, or deprecated features that may affect existing simulations or custom scripts.
