CVE-2023-27398
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-20304)
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, which can be exploited to execute arbitrary code 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.
-
Identify if Tecnomatix Plant Simulation is installedCheck for the application in typical installation directories such as C:\Program Files\Siemens\Tecnomatix_Plant_Simulation or C:\Program Files (x86)\Siemens\Tecnomatix_Plant_Simulation. Also check the Windows Start Menu for Siemens Tecnomatix Plant Simulation.Affected if The product is present on the system
-
Determine installed versionLocate the Plant Simulation executable (typically PlantSimulation.exe) and check its version properties. Right-click the executable, select Properties, and view the Details tab. Alternatively, check the file version information using PowerShell: Get-Item 'C:\Program Files\Siemens\Tecnomatix_Plant_Simulation\PlantSimulation.exe' | Select-Object VersionInfo.Affected if The version shown is earlier than 2201.0006 (such as 2201.0005, V2201, or any version below 2201.0006)
-
Verify SPP file handling is accessibleSPP files are simulation package files used by Plant Simulation. Check if the application has file association handlers registered for .spp extensions. Look in Windows Registry under HKCR\.spp or test by attempting to open an SPP file through the application.Affected if The application can open or parse SPP files, which is the vulnerable feature
-
Inspect recent SPP file accessCheck for recently opened SPP files in the application's recent files list, or examine Windows prefetch/temp directories for SPP files that may have been opened. Review the application's file history or recent documents folder.Affected if Any SPP files from untrusted sources have been opened recently, indicating potential exploitation attempt
A system is affected if Tecnomatix Plant Simulation is installed with a version number lower than 2201.0006 and the application has the ability to parse SPP files, which is the default behavior.

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 version V2201.0006 or later to remediate this vulnerability. Until the patch is applied, avoid opening untrusted SPP files from unknown or untrusted sources.
2201.0006 or later
- 1. Identify the current version of Tecnomatix Plant Simulation installed by opening the application and navigating to Help > About or checking in the Windows Programs list
- 2. Download Tecnomatix Plant Simulation version 2201.0006 or later from the Siemens Industry Online Support portal (support.industry.siemens.com)
- 3. Create a backup of all existing Plant Simulation projects, libraries, and custom configurations
- 4. Uninstall the current version of Tecnomatix Plant Simulation through Windows Control Panel > Programs and Features
- 5. Install the downloaded version 2201.0006 (or later) by running the installer with administrative privileges
- 6. Follow the on-screen installation prompts and restart the system if prompted
- 7. After installation, verify the version by checking Help > About to confirm V2201.0006 or later is installed
- 8. Re-import backed-up projects and validate functionality
