CVE-2023-27405
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-20432)
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 versions before V2201.0006 contain an out-of-bounds read vulnerability when parsing SPP files. The vulnerability occurs when the parser reads past the end of an allocated memory structure, leading to memory corruption that can be exploited for 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 installationOpen Windows Settings > Apps & features (or use 'appwiz.cpl') and search for 'Tecnomatix Plant Simulation' in the installed programs listAffected if The software is not listed, indicating it is not installed and therefore not affected by this specific vulnerability in this product
-
Identify installed version numberOpen Tecnomatix Plant Simulation, then navigate to Help > About, or locate the executable (usually in Program Files/Siemens) and right-click to view Properties > Details for the File VersionAffected if Unable to determine version - manual verification required before proceeding
-
Compare version against affected rangeIf version is found, compare the full version string to 2201.0006 - specifically check if it is below this version (versions like 2201.0005, 13.1, etc.)Affected if Version is below 2201.0006 - for example 2201.0005, 13.0, or any version with a number less than 0006 in the V2201 line
-
Verify SPP file processing capabilityAttempt to locate or confirm whether the installation includes SPP file parsing functionality - this is typically a native capability of the software used for plant simulation dataAffected if Software can open, import, or parse .spp files - the vulnerability is triggered during SPP file parsing even without opening a malicious file yet
If the installed version is below 2201.0006 AND the software includes SPP file parsing capability, the environment is vulnerable to CVE-2023-27405 when processing 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. Until patched, refrain from opening SPP files from untrusted sources.
V2201.0006
- 1. Close any running instances of Tecnomatix Plant Simulation
- 2. Obtain the fixed version V2201.0006 from the official Siemens distribution channel (e.g., Siemens Support Portal, Siemens Digital Industries Software)
- 3. Verify the integrity of the downloaded installer using checksums if provided
- 4. Run the installer and follow the on-screen prompts to upgrade Tecnomatix Plant Simulation to version V2201.0006
- 5. After installation, verify the version by checking 'Help > About Tecnomatix Plant Simulation' to confirm V2201.0006 is installed
- 6. Test critical SPP file workflows to ensure the upgrade does not affect your existing models and simulations
