CVE-2023-24991
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-19813)
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 confidenceTecnomatix Plant Simulation contains an out-of-bounds write vulnerability when parsing specially crafted SPP files. The application writes past the end of an allocated buffer during SPP file parsing, allowing an attacker to achieve arbitrary code execution in the context of the current process.

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.
-
Confirm Tecnomatix Plant Simulation installationCheck for the presence of Tecnomatix Plant Simulation in the Windows Programs and Features list, or look for the installation directory typically under C:\Program Files\Siemens\Tecnomatix_Plant_SimulationAffected if The software is installed on the system
-
Identify installed versionOpen the Windows Registry under HKLM\SOFTWARE\Siemens\Tecnomatix\PlantSimulation\ and look for the Version value, or right-click the PlantSimulation.exe executable in the installation folder and view Properties > DetailsAffected if Version cannot be determined or is not visible
-
Compare version against vulnerability rangeIf version is found, compare the full version number (including build/sub-version) to 2201.0006Affected if Installed version is less than 2201.0006 (for example, 2201.0005, V2201, or any earlier release)
-
Verify SPP file handling capabilityConfirm the application can open .spp files by checking if the software includes SPP file import functionality or by locating .spp file type associationsAffected if The application has the capability to parse SPP files and the version is vulnerable
The environment is affected if Tecnomatix Plant Simulation is installed with a version number lower than 2201.0006 and the application can parse 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 Tecnomatix Plant Simulation to version V2201.0006 or later to remediate this vulnerability; refrain from opening untrusted SPP files from unknown or unverified sources.
V2201.0006
- Verify current Tecnomatix Plant Simulation version by opening the application and navigating to Help > About, or checking the installation directory for version information
- Download Tecnomatix Plant Simulation version V2201.0006 or later from the official Siemens support portal (cert-portal.siemens.com)
- Ensure all SPP files are backed up before performing the upgrade
- Close all instances of Tecnomatix Plant Simulation
- Run the installer for version V2201.0006 and follow the installation wizard prompts
- After installation, verify the version by checking Help > About to confirm V2201.0006 is installed
- Test that existing SPP files open correctly in the upgraded version
