Security readout for executives and security teams
Plain-English summary
Siemens Tecnomatix Plant Simulation can crash or run attacker-controlled code when a user opens a malicious PAR file. The issue affects specific V2201 and V2302 builds before the fixed version thresholds. It needs user interaction, but successful exploitation could affect confidentiality, integrity, and availability on the user’s workstation.
Executive priority
Treat this as high priority where Tecnomatix Plant Simulation is used in operational or engineering workflows. It is not internet-facing by default from the evidence provided, but malicious project-file handling can still create a practical route to workstation compromise.
Technical view
CVE-2023-37247 is a heap-based buffer overflow in Siemens Tecnomatix Plant Simulation while parsing specially crafted PAR files. Affected versions are V2201 before V2201.0008 and V2302 before V2302.0002. CVSS v3.1 is 7.8, local attack vector, low complexity, no privileges, user interaction required, with code execution in the current process context.
Likely exposure
Exposure is most likely on engineering, simulation, manufacturing, or OT-adjacent workstations that open PAR files in Tecnomatix Plant Simulation V2201 or V2302. Systems not running those product lines, or already at the listed fixed thresholds or later, are not indicated as affected by the provided sources.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. The CVSS vector indicates proof-of-concept exploit maturity, but exploitation still requires a target user or workflow to open a specially crafted PAR file in the affected application.
Researcher notes
Focus validation on file-association and document-ingest paths for PAR files, not network scanning alone. Evidence supports heap overflow and code execution in process context, but the bundle does not provide exploit details, telemetry, or compensating controls beyond vendor remediation.
Mitigation direction
- Review Siemens SSA-764801 for official remediation guidance.
- Upgrade V2201 installations to V2201.0008 or later where applicable.
- Upgrade V2302 installations to V2302.0002 or later where applicable.
- Restrict untrusted PAR file handling until remediation is complete.
- Train affected users to avoid unsolicited simulation files.
Validation and detection
- Inventory Tecnomatix Plant Simulation installations and versions.
- Identify hosts running V2201 before V2201.0008.
- Identify hosts running V2302 before V2302.0002.
- Confirm whether PAR files are received from external parties.
- Verify upgraded hosts report non-affected versions.

Heap-based Buffer Overflow
Heap-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
