CVE-2024-54095 Siemens CVE debrief

CVE-2024-54095 is a high-severity integer underflow vulnerability in Siemens Solid Edge SE2024, published December 10, 2024. The flaw exists in the application's parsing of PAR (part) files, where specially crafted input can trigger an integer underflow condition. Successful exploitation allows arbitrary code execution within the context of the current process, with a CVSS 3.1 score of 7.8 (HIGH). The attack vector is local, requiring user interaction to open a malicious file, but needs no privileges and has low attack complexity. Siemens has released V224.0 Update 10 to address this vulnerability. CISA and Siemens both recommend updating immediately and avoiding untrusted PAR files as an interim mitigation.

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, OT/ICS security practitioners, and IT administrators managing product lifecycle management (PLM) environments should prioritize this patch.

Technical summary

An integer underflow vulnerability in the PAR file parser of Siemens Solid Edge SE2024 allows attackers to achieve arbitrary code execution by tricking users into opening maliciously crafted part files. The vulnerability stems from improper validation during file parsing operations, resulting in memory corruption that can be leveraged for process-level code execution. The CVSS 3.1 vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H reflects local attack vector with user interaction required but no privilege prerequisites, yielding high impacts across confidentiality, integrity, and availability.

Defensive priority

HIGH

Recommended defensive actions

  • Apply Siemens Solid Edge V224.0 Update 10 or later immediately to remediate the integer underflow vulnerability
  • Implement user awareness training to prevent opening untrusted PAR files from unknown sources
  • Consider application whitelisting and endpoint protection to detect anomalous Solid Edge process behavior
  • Review and apply CISA ICS recommended practices for defense-in-depth strategies in engineering workstation environments

Evidence notes

Vulnerability disclosed via CISA ICS Advisory ICSA-24-347-07 and Siemens Security Advisory SSA-730188. Affected product confirmed as Solid Edge SE2024. Remediation guidance specifies V224.0 Update 10 or later.
