CVE-2026-23716
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in Simcenter Femap (All versions < V2512), Simcenter Nastran (All versions < V2512). The affected applications contains an out of bounds read vulnerability while parsing specially crafted XDB files. This could allow an attacker to execute code in the context of the current process.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability exists in Simcenter Femap and Simcenter Nastran when parsing XDB files. The vulnerability occurs during the parsing of specially crafted XDB files, allowing an attacker to potentially execute arbitrary code in the context of the current process by triggering memory corruption.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Simcenter Femap versionUse the software's About dialog or check the installed program version through system settings or the executable's propertiesAffected if Version is below 2512.0000
-
Check Simcenter Nastran versionUse the software's About dialog or check the installed program version through system settings or the executable's propertiesAffected if Version is below 2512.0000
-
Identify XDB file usageReview whether your workflow involves opening or importing XDB files in the softwareAffected if XDB files are opened or imported in either product
You are affected if either Simcenter Femap or Simcenter Nastran is installed at a version below 2512.0000 AND the software is used to parse XDB files.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2512.0000
Upgrade to Simcenter Femap and Simcenter Nastran version V2512 or later. Until then, avoid opening untrusted XDB files and implement application whitelisting to reduce attack surface.
V2512.0000 or later for both Simcenter Femap and Simcenter Nastran
- 1. Identify the current installed version of Simcenter Femap or Simcenter Nastran.
- 2. Obtain the V2512 release or later from official Siemens channels (Siemens Support or cert-portal.siemens.com).
- 3. Back up all existing project files, templates, and custom configurations.
- 4. Uninstall the current version of the affected application.
- 5. Install Simcenter Femap V2512.0000 or later / Simcenter Nastran V2512.0000 or later.
- 6. Re-apply any custom configurations or preferences from backups.
- 7. Validate that XDB files can be opened and parsed correctly in the updated version.
