CVE-2023-37246
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 V2201 (All versions < V2201.0008), Tecnomatix Plant Simulation V2302 (All versions < V2302.0002). The affected application is vulnerable to heap-based buffer overflow while parsing specially crafted PRT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21109)
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 is vulnerable to a heap-based buffer overflow when parsing specially crafted PRT files. An attacker can exploit this to execute arbitrary code in the context of the current process, potentially achieving local privilege escalation or remote code execution depending on the application's privileges.

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 application in typical installation paths such as C:\Program Files\Siemens\Tecnomatix_Plant_Simulation or check Start Menu for Siemens Tecnomatix entries. Look for executables named Plant_Simulation.exe or similar.Affected if The application is not found on the system.
-
Identify installed version numberRight-click the Plant Simulation executable, select Properties, and check the Details tab for the Product Version. Alternatively, launch the application and navigate to Help > About to view the version.Affected if Unable to determine the version number from the executable or application.
-
Compare version to affected rangesCheck if the installed version falls within: 2201.0 through 2201.0007 (all versions between 2201 and 2201.0007), or 2302.0 through 2302.0001. Versions outside these ranges (2201.0008 or higher, 2302.0002 or higher) are not affected.Affected if The installed version is 2201.x where x < 8, or 2302.x where x < 2.
-
Assess exposure to PRT file parsingDetermine if the system processes PRT (part) files using Tecnomatix Plant Simulation. Check recent file open activities or look for PRT file associations with the application. Review any logs if available.Affected if Users routinely open PRT files from untrusted or unknown sources using this application.
The environment is affected if Tecnomatix Plant Simulation is installed with a version between 2201.0 and 2201.0007, or between 2302.0 and 2302.0001, and users may open PRT files from untrusted sources.

dbcve · scoped2201.00082302.0002
Apply vendor-supplied updates: upgrade to V2201.0008, V2302.0002, or later versions. Until patched, avoid opening untrusted PRT files from unknown sources.
Tecnomatix Plant Simulation V2201.0008 or V2302.0002
- 1. Identify the currently installed Tecnomatix Plant Simulation version (V2201.x or V2302.x)
- 2. For V2201 branch users: Upgrade to version V2201.0008
- 3. For V2302 branch users: Upgrade to version V2302.0002
- 4. Obtain the update from the official Siemens cert-portal or Siemens Support portal
- 5. Backup any critical PRT files and simulation data before upgrading
- 6. Install the updated version and verify the application runs without errors
