CVE-2024-24920
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 < V2401.0000). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted Catia MODEL file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21710)
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 an out-of-bounds write vulnerability when parsing Catia MODEL files. The parsing logic writes past the end of an allocated buffer, allowing an attacker to achieve code execution in the context of the current process by using a specially crafted malicious file.

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 if Simcenter Femap is installedLook for the Simcenter Femap executable (femap.exe) in typical installation directories such as C:\Program Files\Siemens\SimcenterFemap or check the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\Simcenter FemapAffected if Simcenter Femap is not found on the system, then the vulnerability does not apply
-
Determine the installed Femap versionRight-click on femap.exe, select Properties, then go to the Details tab to view the Product version. Alternatively, launch Femap and go to Help > About Simcenter Femap to see the exact version numberAffected if The version displayed is below 2401.0000 (for example, 2301.0000, 2201.0000, or any version number less than 2401.0000)
-
Verify Catia MODEL file import capability existsIn Femap, check if the Catia MODEL import option is available. This is typically found under File > Import or by looking for Catia-related import handlers in the application's import menuAffected if The Catia MODEL file import feature is present and functional in the installed version
You are affected if Simcenter Femap is installed with any version below 2401.0000 and the Catia MODEL file import functionality is available in the application.

dbcve · scoped2401.0000
Update Simcenter Femap to version V2401.0000 or later to patch the vulnerability. Until updated, do not open untrusted Catia MODEL files with the application.
V2401.0000 or later
- 1. Verify current installed version of Simcenter Femap by checking the About section or program properties.
- 2. Backup all important Femap project files and configurations before upgrading.
- 3. Obtain Simcenter Femap version 2401.0000 or later from official Siemens channels (Siemens Support Center or cert-portal.siemens.com).
- 4. Uninstall the current version of Simcenter Femap.
- 5. Install version 2401.0000 or later of Simcenter Femap.
- 6. Verify the installation was successful and the version is correctly reported as V2401.0000 or higher.
- 7. Test that Catia MODEL file parsing functions correctly in the updated version.
