CVE-2024-47046
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 V2306 (All versions), Simcenter Femap V2401 (All versions), Simcenter Femap V2406 (All versions). The affected application is vulnerable to memory corruption while parsing specially crafted BDF 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 confidenceSimcenter Femap contains a memory corruption vulnerability in its BDF file parser. Specially crafted BDF files can trigger out-of-bounds memory access during parsing, potentially allowing an attacker to achieve code execution in the context of the running process.

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.
-
Locate installed Simcenter applicationIdentify the Simcenter Femap or Simcenter Nastran installation on the system and retrieve its version information from the application properties, about dialog, or installation metadataAffected if The application is present on the system and version cannot be determined or is below 2406.5000
-
Compare version to affected rangeExtract the exact version number of the installed Simcenter Nastran build and compare it against 2406.5000 using your organization's software inventory or version reporting toolsAffected if The installed version is lower than 2406.5000, indicating the vulnerable build is present
-
Verify BDF file parsing capabilityConfirm that the BDF (Bulk Data File) parser module is available and enabled in the installed Simcenter application, typically by checking the application's feature set or parsing capabilitiesAffected if BDF parsing functionality is present and operational in the vulnerable version
-
Check for recent BDF file processingReview application logs, recent file access history, or file association settings to determine whether BDF files have been opened or processed in the applicationAffected if BDF files have been opened in the affected application version, creating potential exploitation conditions
A system is affected if Simcenter Nastran version is below 2406.5000 and BDF files can be parsed by the application, as the vulnerability triggers during BDF file processing.

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 · scoped2406.5000
Do not open untrusted or unverified BDF files in Simcenter Femap. Apply vendor patches when released. Implement input validation and bounds checking in BDF parsing code.
Simcenter Nastran 2406.5000 or later
- 1. Identify the installed Simcenter Nastran version by checking the software 'About' information or using the NASTRAN version command
- 2. Download Simcenter Nastran version 2406.5000 or later from the Siemens PLM Community or official download portal
- 3. Uninstall the current version of Simcenter Nastran
- 4. Install the updated version (2406.5000 or newer)
- 5. Verify the installation by checking the version number in the product
- 6. Test critical BDF file workflows to ensure functionality
