A vulnerability has been identified in Tecnomatix Plant Simulation V2201 (All versions < V2201.0008), Tecnomatix Plant Simulation V2302 (All versions < V2302.0002). The affected application is vulnerable to stack-based buffer overflow while parsing specially crafted STP files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21054)

Security readout for executives and security teams

Plain-English summary

This flaw affects Siemens Tecnomatix Plant Simulation when it opens a malicious STP file. If a user imports or opens such a file, an attacker could run code with that user’s application privileges. It is high risk for engineering environments that exchange CAD or simulation files externally.

Executive priority

Treat this as a high-priority engineering workstation risk, not an internet-exposed server emergency. Prioritize teams handling external design files and systems supporting manufacturing or simulation workflows.

Technical view

CVE-2023-37374 is a CWE-121 stack-based buffer overflow in STP file parsing in Tecnomatix Plant Simulation V2201 before V2201.0008 and V2302 before V2302.0002. CVSS 3.1 is 7.8: local attack vector, low complexity, no privileges, user interaction required, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to organizations running the affected Siemens Tecnomatix Plant Simulation versions, especially users who open STP files from suppliers, customers, shared repositories, or email attachments.

Exploitation context

The CVE data does not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation requires local user interaction by opening a specially crafted STP file.

Researcher notes

The public bundle identifies ZDI-CAN-21054, CWE-121, affected version ranges, and code execution in the current process. It does not include exploit details, observed exploitation, or broader affected product claims.

Mitigation direction

  • Upgrade V2201 deployments to V2201.0008 or later.
  • Upgrade V2302 deployments to V2302.0002 or later.
  • Check Siemens SSA-764801 for current vendor guidance.
  • Restrict opening STP files from untrusted sources until remediated.
  • Route external STP files through established file-handling controls.

Validation and detection

  • Inventory Tecnomatix Plant Simulation V2201 and V2302 installations.
  • Confirm whether each installation is below the fixed version threshold.
  • Review engineering workflows that receive or import STP files.
  • Verify upgraded hosts report V2201.0008, V2302.0002, or later.
  • Confirm users know not to open unexpected STP files.
