CVE-2023-27400
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 · uneditedA vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V2201.0006). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-20300)
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 confidenceThis is an out-of-bounds write vulnerability in Tecnomatix Plant Simulation where parsing a specially crafted SPP file causes the application to write past the end of an allocated buffer. Successful exploitation allows arbitrary code execution in the context of the current process, making it a high-severity memory corruption issue.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate Tecnomatix Plant Simulation installationSearch for the Plant Simulation executable (typically PlantSimulation.exe) in program directories such as C:\Program Files\Siemens\Tecnomatix_Plant_Simulation or check Windows Registry under HKLM\SOFTWARE\Siemens\Tecnomatix for the installation pathAffected if The software is installed on the system
-
Identify installed version numberRight-click the PlantSimulation.exe file, select Properties, and view the Details tab for the Product Version, or use the command: Get-Item 'C:\Program Files\Siemens\Tecnomatix_Plant_Simulation\PlantSimulation.exe' | Select-Object VersionInfoAffected if Version cannot be determined or is lower than 2201.0006
-
Compare version to affected rangeCompare the identified version string against 2201.0006 - versions earlier than 2201.0006 (such as 2201.0005, 2201, 2000.x, etc.) are in the affected rangeAffected if Installed version is less than 2201.0006 (for example: 2201.0005, 2201.0004, 2201, V2000, etc.)
-
Confirm SPP file handling capabilityVerify the installation includes SPP file association or the ability to open .spp files, which is the core file format processed by Plant SimulationAffected if The software can open or parse SPP files and the version is below 2201.0006
You are affected if Tecnomatix Plant Simulation is installed with any version lower than 2201.0006 and the software is capable of parsing SPP files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2201.0006
Upgrade to Tecnomatix Plant Simulation version V2201.0006 or later. Until patched, avoid opening SPP files from untrusted or unknown sources to prevent exploitation.
V2201.0006 or later
- Obtain the fixed version V2201.0006 or later from the official Siemens support portal (cert-portal.siemens.com)
- Verify the current installed version of Tecnomatix Plant Simulation
- Download the V2201.0006 update or later version
- Apply the update following standard Siemens installation procedures
- Restart the application after update installation
- Validate the update was successful by checking the installed version
