CVE-2024-32065 Siemens CVE debrief

Who should care

Engineering teams using Simcenter Femap for finite element analysis and CAD preprocessing, particularly in aerospace, automotive, and manufacturing sectors where IGS file exchange is common. Security teams responsible for OT/ICS environments and software asset management should prioritize patching.

Technical summary

The vulnerability stems from an out-of-bounds read past the end of an allocated structure during IGS file parsing in Simcenter Femap. This memory safety defect can be triggered by a malformed IGS file and may lead to arbitrary code execution within the process context. The attack requires local access and user interaction (opening a malicious file), with no privileges required. The fix in V2406 addresses the parsing logic to prevent the out-of-bounds access.

Defensive priority

HIGH

Recommended defensive actions

• Update Simcenter Femap to V2406 or later version
• Avoid opening untrusted IGS files in affected applications
• Avoid opening untrusted IGS, BDF, or BMP files using Simcenter Femap
• Apply defense-in-depth practices for industrial control systems per CISA guidance

Evidence notes
