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 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 confidence

An out-of-bounds read vulnerability exists in Simcenter Femap and Simcenter Nastran (all versions prior to V2512) when parsing specially crafted XDB files. This memory corruption during file parsing could allow an attacker to achieve code execution within the context of the current user process.

MitigationUpgrade Simcenter Femap and Nastran to version V2512 or later. Until patches are applied, refrain from opening untrusted or unverified XDB files from external 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. Check if Simcenter Femap is installed
    Look for Simcenter Femap in the installed programs list on Windows (Control Panel > Programs and Features) or check the installation directory typically found under C:\Program Files\Siemens\ or C:\Program Files (x86)\Siemens\
    Affected if Simcenter Femap is installed and its version is less than 2512.0000
  2. Check if Simcenter Nastran is installed
    Look for Simcenter Nastran in the installed programs list on Windows (Control Panel > Programs and Features) or check the installation directory typically found under C:\Program Files\Siemens\ or C:\Program Files (x86)\Siemens\
    Affected if Simcenter Nastran is installed and its version is less than 2512.0000
  3. Determine the exact version of installed Simcenter Femap
    Open the application and navigate to Help > About, or check the version information in the application's executable file properties, or review the installation log files
    Affected if The displayed version is less than 2512.0000 or the version cannot be determined to be 2512.0000 or higher
  4. Determine the exact version of installed Simcenter Nastran
    Open the application and navigate to Help > About, or check the version information in the application's executable file properties, or review the installation log files
    Affected if The displayed version is less than 2512.0000 or the version cannot be determined to be 2512.0000 or higher
  5. Confirm XDB file handling capability is present
    Verify that the XDB file import/export module is available in the product by checking the File menu for XDB import options or reviewing installed plugins/modules
    Affected if The product includes XDB file parsing functionality and the version is below 2512.0000

The environment is affected if either Simcenter Femap or Simcenter Nastran is installed with a version number lower than 2512.0000 and the software has the ability to open or parse XDB files.
