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 is vulnerable to stack-based buffer while parsing specially crafted SPP files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-20433)

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 stack-based buffer overflow vulnerability when parsing specially crafted SPP files. An attacker can exploit this by supplying a malicious SPP file to trigger the overflow and achieve code execution in the context of the current process.

MitigationUpgrade Tecnomatix Plant Simulation to version V2201.0006 or later to apply the vendor patch that addresses the buffer overflow in SPP file parsing.

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 installation
    Check for the presence of Tecnomatix Plant Simulation in the system. Look in standard installation directories (e.g., C:\Program Files\Siemens\ or C:\Program Files (x86)\Siemens\) or check Windows Registry under HKLM\SOFTWARE\Siemens\ for Plant Simulation entries.
    Affected if Tecnomatix Plant Simulation is installed on the system.
  2. Determine installed version
    Locate the Plant Simulation executable (typically named something like PlantSimulation.exe) and check its file version property, or check the software's About/Help dialog for the version number.
    Affected if The installed version is any version prior to 2201.0006.
  3. Identify SPP file association
    Check if .spp file extension is associated with Plant Simulation. This can be verified by searching for .spp files on the system, checking file type associations in Windows, or examining the Plant Simulation configuration for supported import formats.
    Affected if The system can process or import SPP files through Plant Simulation.
  4. Audit recent SPP file activity
    Search for .spp files on accessible drives, particularly in recent download folders, document directories, or paths used for Plant Simulation data import. Use file system auditing or look at recent file access timestamps.
    Affected if Suspicious or unexpected SPP files are found, especially from untrusted sources.

The environment is affected if Tecnomatix Plant Simulation version is installed and is lower than 2201.0006, and the system has the capability to process SPP files.

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

Upgrade Tecnomatix Plant Simulation to version V2201.0006 or later to apply the vendor patch that addresses the buffer overflow in SPP file parsing.

Recommended fix High confidence

V2201.0006

  1. Download Tecnomatix Plant Simulation version V2201.0006 or later from the official Siemens support portal (cert-portal.siemens.com or support.industry.siemens.com)
  2. Install the updated version over the existing installation, following standard Siemens installation procedures
  3. Verify the installed version is V2201.0006 or higher after installation completes
