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 application is vulnerable to heap-based buffer overflow while parsing specially crafted NDB 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

Simcenter Femap and Nastran versions prior to V2512 contain a heap-based buffer overflow vulnerability when parsing specially crafted NDB files. An attacker can exploit this by convincing a user to open a malicious NDB file, potentially executing arbitrary code in the context of the user's session.

MitigationUpgrade to Simcenter Femap and Nastran version V2512 or later. Until patches are applied, avoid opening NDB files from untrusted sources.

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. Identify installed Simcenter product
    Check Programs and Features (Windows) or use the application Help > About dialog to determine if Simcenter Femap, Simcenter Nastran, or both are installed
    Affected if Either product is installed with a version number lower than 2512.0000
  2. Determine installed version number
    Open the application and navigate to Help > About, or right-click the executable in the installation directory and view Properties > Details to find the version
    Affected if Version shown is below 2512.0000 (for example, 2510.0000, 2024.x, etc.)
  3. Confirm NDB file handling capability
    Attempt to locate .ndb files or check if the software includes NDB database parsing functionality through the application's file open dialog or documentation
    Affected if The installed version includes the ability to open or parse NDB files and the version is below 2512.0000
  4. Review recent file access
    Check the application's recent files list or Windows Jump List for any recently opened .ndb files from untrusted or unknown sources
    Affected if A malicious NDB file was opened and the software version is below 2512.0000

You are affected if Simcenter Femap or Nastran is installed with any version prior to 2512.0000 and the software has been used to open NDB files from untrusted sources.
