Security readout for executives and security teams
Plain-English summary
This flaw affects Siemens CAD/engineering file import components. A malicious IGS file could crash the application or potentially run code as the user who opens it. Business risk is highest where engineers exchange files with external parties or open supplier/customer CAD data.
Executive priority
Prioritize remediation for engineering teams that handle external CAD files. This is not evidenced as actively exploited in the provided sources, but the potential for code execution and the common use of file exchange make timely patching appropriate.
Technical view
CVE-2025-40936 is a CWE-125 out-of-bounds read in Siemens PS/IGES Parasolid Translator Component, Simcenter Femap, and Solid Edge while parsing crafted IGS files. CVSS 3.1 is 7.8 with local attack vector, low complexity, no privileges, and required user interaction.
Likely exposure
Exposure is likely limited to endpoints or engineering environments running affected Siemens products before PS/IGES Parasolid Translator V29.0.258, Simcenter Femap V2512.0003, or Solid Edge V226.00 Update 03, especially where IGS files are imported from outside the organization.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires a user to open or import a specially crafted IGS file in an affected application. Impact may include application crash or code execution in the current process context.
Researcher notes
Key constraints are user interaction and local file parsing. The source version records are sparse, but the description provides affected version thresholds. Do not assume broader Siemens products are affected without advisory confirmation.
Mitigation direction
- Upgrade PS/IGES Parasolid Translator to V29.0.258 or later where deployed.
- Upgrade Simcenter Femap to V2512.0003 or later where deployed.
- Upgrade Solid Edge to V226.00 Update 03 or later where deployed.
- Restrict opening IGS files from untrusted or unexpected sources.
- Review Siemens advisories for any product-specific workarounds or deployment guidance.
Validation and detection
- Inventory Siemens CAD and translator installations across engineering workstations.
- Compare installed versions against the affected version thresholds in Siemens advisories.
- Identify workflows that import IGS files from suppliers, customers, or public sources.
- Confirm patched applications still handle required IGS workflows after updates.
- Review recent CAD crashes associated with IGS import activity.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
