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 application contains a memory corruption vulnerability while parsing specially crafted SPP files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-20303, ZDI-CAN-20348)

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 a memory corruption vulnerability when parsing specially crafted SPP files. An attacker can trigger this vulnerability by providing a malicious SPP file to the affected application, potentially achieving arbitrary code execution in the context of the current process.

MitigationUpgrade to Tecnomatix Plant Simulation version V2201.0006 or later. Until patched, avoid opening untrusted SPP files from unknown or untrusted sources.

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 Siemens Tecnomatix Plant Simulation application in the system. Common installation paths include C:\Program Files\Siemens\Tecnomatix_Plant_Simulation or C:\Program Files (x86)\Siemens\Tecnomatix_Plant_Simulation. Look for the executable file PlantSimulation.exe in these directories.
    Affected if The application directory exists and contains PlantSimulation.exe
  2. Determine the installed version
    Right-click on PlantSimulation.exe, select Properties, and check the File Version tab. Alternatively, open the application and navigate to Help > About Tecnomatix Plant Simulation to view the version information.
    Affected if The version number returned is lower than 2201.0006 (for example, 2201.0005, V2201, or any 15.x/16.x/17.x/18.x/19.x/20.x release)
  3. Confirm SPP file handling capability
    Check if the application has the capability to open .spp files, which are Plant Simulation files. This can be verified by attempting to open a .spp file or checking file association settings for .spp extensions in the Windows registry under HKCR\.spp.
    Affected if The .spp file extension is associated with the installed Tecnomatix Plant Simulation application
  4. Check for recent SPP file processing activity
    Review recent files opened by the application or check the application's recent documents list for .spp files. On Windows, check the Jump List or recent items in the application for any .spp files that may have been opened.
    Affected if Any .spp files have been opened or processed by the application

If Tecnomatix Plant Simulation version is below 2201.0006 and the application processes .spp files, the environment is vulnerable to this memory corruption flaw.
