CVE-2023-24996
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-19818)
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 parsing logic writes past the end of an allocated buffer, which can be exploited 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 is installedLook for the program in standard installation directories such as C:\Program Files\Siemens\Tecnomatix_Plant_Simulation, or check the Windows Programs and Features list for any Siemens Tecnomatix Plant Simulation entry.Affected if The software is present on the system.
-
Determine the installed version numberRight-click the Plant Simulation executable (typically named Plant_Simulation.exe or similar in the installation folder), select Properties, and view the Details tab for the Product Version field. Alternatively, open the program and check Help > About Tecnomatix Plant Simulation.Affected if A version number is displayed.
-
Compare version against the affected rangeCompare the identified version to the vulnerable range: any version earlier than 2201.0006 is affected. For example, versions such as 2201.0005, 2201.0004, 2100.0001, or older releases are within the vulnerable range.Affected if The installed version is 2201.0005 or lower, or any version number below 2201.0006.
-
Identify SPP file usage in the environmentSearch the system for .spp files in user directories, shared folders, or recent project locations using File Explorer or the command line: dir /s /b C:\*.sppAffected if SPP files exist on the system or have been recently opened.
The environment is affected if Tecnomatix Plant Simulation version 2201.0005 or earlier is installed and the system handles 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 V2201.0006 or later. Until patched, do not open SPP files from untrusted sources.
Tecnomatix Plant Simulation V2201.0006 or later
- Back up all Plant Simulation projects, libraries, and configuration data
- Download Tecnomatix Plant Simulation V2201.0006 or later from Siemens Support (cert-portal.siemens.com or siemens.com/support)
- Uninstall the current vulnerable version of Plant Simulation, or use the upgrade installer if supported
- Install the fixed version V2201.0006
- Restore the backed-up projects and configuration data
- Verify the installation by checking Help > About shows version V2201.0006 or later
- Test that SPP files can be opened and used normally
