CVE-2024-54093 Siemens CVE debrief

Who should care

Organizations using Siemens Solid Edge SE2024 for CAD/CAM/CAE operations, particularly in manufacturing, aerospace, automotive, and industrial design sectors. Security teams responsible for engineering workstation protection and supply chain security for design file exchanges.

Technical summary

CVE-2024-54093 is a heap-based buffer overflow in Siemens Solid Edge SE2024 triggered during parsing of specially crafted ASM assembly files. The vulnerability exists in the application's file parsing logic and can result in arbitrary code execution within the context of the current process. The attack requires local access and user interaction (opening a malicious file), with no privileges required. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates high impacts to confidentiality, integrity, and availability if exploited. Siemens has addressed this in V224.0 Update 5.

Defensive priority

HIGH

Recommended defensive actions

• Apply Siemens Solid Edge SE2024 V224.0 Update 5 or later immediately
• Implement user training to avoid opening untrusted ASM files from unknown sources
• Consider application whitelisting and least-privilege execution for CAD workstations
• Monitor for anomalous Solid Edge process behavior or unexpected child processes
