CVE-2023-27406
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 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-20449)
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 confidenceA stack-based buffer overflow vulnerability exists in Tecnomatix Plant Simulation when parsing specially crafted SPP files. The vulnerability allows an attacker to overwrite stack memory boundaries by providing malicious input, potentially achieving arbitrary code execution within the context of the running process. This is a classic memory corruption vulnerability in file parsing logic.

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.
-
Check installed Tecnomatix Plant Simulation versionOpen Windows Programs and Features (appwiz.cpl), locate Siemens Tecnomatix Plant Simulation, and note the version shown in the Version columnAffected if Version displayed is less than 2201.0006
-
Verify application file versionNavigate to the installation directory (typically C:\Program Files\Siemens\Tecnomatix_Plant_Simulation\), right-click Plant_Simulation.exe, select Properties, and check the File Version under the Details tabAffected if File version is less than 2201.0006 or the version field shows a build number below 2201.0006
-
Confirm SPP file usageSearch the system for .spp files or check recent documents within the Plant Simulation application to identify if SPP files are being openedAffected if SPP files are opened or processed by the vulnerable version
-
Check process context when opening SPP filesOpen Plant Simulation and attempt to load an SPP file while monitoring with Process Explorer or similar tool to confirm the application parses this file typeAffected if The application loads and parses SPP files (this is the vulnerable code path)
User is affected if Tecnomatix Plant Simulation version is below 2201.0006 AND the application is used to open SPP files from any source.

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 the vulnerability. Until upgraded, exercise caution when opening SPP files from untrusted sources.
V2201.0006
- Upgrade Tecnomatix Plant Simulation to version V2201.0006 or later
- Obtain the updated version from Siemens official distribution channels or Siemens Product Lifecycle Management (PLM) software downloads
- Verify the installation by checking the application version in the About section
