CVE-2023-27402
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 applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted SPP files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-20334)
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 read vulnerability when parsing SPP files. The application reads past the end of an allocated buffer structure during parsing, which can lead to memory corruption and potential 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.
-
Verify if Tecnomatix Plant Simulation is installedCheck the Windows registry under HKLM\SOFTWARE\Siemens\Tecnomatix_Plant_Simulation\ or look for the installation directory (typically C:\Program Files\Siemens\Tecnomatix Plant Simulation)Affected if The product is found on the system
-
Determine the installed versionLocate the executable (Plant_Simulation.exe) and check its version property, or check the version in the Windows registry under the product keyAffected if The installed version is below 2201.0006
-
Verify the SPP parser component existsCheck for the presence of SPP file parsing DLLs in the installation directory, typically in the bin or lib folderAffected if SPP parsing libraries are present in the installation folder
-
Confirm SPP file handling is enabledCheck if the SPP file type handler is registered in Windows (look for .spp extension associations) or inspect the application's configuration files for SPP import settingsAffected if SPP file handling is registered or enabled in the application
The system is affected if Tecnomatix Plant Simulation is installed with a version lower than 2201.0006 and SPP file parsing functionality is present and enabled.
Generated from the published advisory. Verify against your own configuration.
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. Avoid opening untrusted SPP files from unknown sources until the patch is applied.
