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 · unedited
A vulnerability has been identified in Simcenter Femap (All versions < V2512), Simcenter Nastran (All versions < V2512). The affected applications contains an out of bounds write 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 confidence

An out-of-bounds write vulnerability exists in Simcenter Femap and Simcenter Nastran when parsing specially crafted XDB files. The vulnerability allows an attacker to achieve code execution in the context of the current process due to insufficient bounds checking during XDB file parsing.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Simcenter Femap version
    Open Simcenter Femap and navigate to Help > About, or right-click the executable file, select Properties, and view the Details tab. Note the version number displayed (typically a four-digit format such as 2406 or 2512).
    Affected if The installed version is less than 2512.0000
  2. Check Simcenter Nastran version
    Open Simcenter Nastran and locate the version information in the About dialog or Help menu, or check the executable file properties under the Details tab.
    Affected if The installed version is less than 2512.0000
  3. Confirm XDB file processing is in use
    Examine recent file history, default import/export settings, or automation scripts to determine whether XDB files are being opened, imported, or processed by either product. XDB is a native database format for finite element model data.
    Affected if The software is configured to handle or import XDB files from any source

The environment is affected if either Simcenter Femap or Simcenter Nastran is installed with a version below 2512.0000 and the software is used to process XDB files.
