CVE-2024-41170 Siemens CVE debrief

A stack-based buffer overflow vulnerability exists in Siemens Tecnomatix Plant Simulation V2302 and V2404 when parsing specially crafted SPP (Plant Simulation Project) files. The flaw allows an attacker to execute arbitrary code within the context of the current process. This vulnerability requires local access and user interaction, as the victim must open a malicious SPP file. The CVSS 3.1 score of 7.8 reflects high impacts to confidentiality, integrity, and availability. CISA published advisory ICSA-24-256-12 on September 10, 2024, with a revision on May 6, 2025 to correct typos. Siemens has released patched versions: V2302.0015 or later for the V2302 branch, and V2404.0004 or later for the V2404 branch.

Who should care

Organizations using Siemens Tecnomatix Plant Simulation for manufacturing process design and simulation, particularly in discrete manufacturing and automotive industries. Security teams responsible for engineering workstation protection, OT/ICS security practitioners, and asset owners with digital manufacturing environments should prioritize patching.

Technical summary

The vulnerability is a stack-based buffer overflow triggered during parsing of malformed SPP (Plant Simulation Project) files in Siemens Tecnomatix Plant Simulation. The affected versions are V2302 (before V2302.0015) and V2404 (before V2404.0004). Successful exploitation allows arbitrary code execution with the privileges of the user running the application. The attack requires the victim to open a malicious file, making social engineering a likely delivery vector. No network-based exploitation is indicated; the attack vector is local (AV:L) with required user interaction (UI:R).

Defensive priority

HIGH

Recommended defensive actions

  • Update Tecnomatix Plant Simulation V2302 to version V2302.0015 or later
  • Update Tecnomatix Plant Simulation V2404 to version V2404.0004 or later
  • Implement user awareness training to avoid opening untrusted SPP files from unknown sources
  • Apply defense-in-depth strategies for industrial control systems per CISA guidance
  • Restrict user permissions to limit impact of potential exploitation
  • Monitor for anomalous process execution in engineering workstation environments
