Several known vulnerabilities affect BIOS (Reference URLs below). So my question is, are the Vulnerability Management tools (such as Nessus, NeXpose, Qualys, etc) technically capable of highlighting BIOS and driver-level vulnerabilities? Is this something that can be detected for example via an authenticated Windows scan?

Nessus does not have a plugin for that CVE. You can check this using the Nessus plugin search. I don't know about the other tools.

In theory it is possible to detect these issues on an authenticated scan, as you can do a WMI query for the BIOS version. It may turn out that there are particular difficulties that prevent this; perhaps the BIOS version doesn't update when you apply the new firmware. Or it may just be that Tenable haven't yet developed such a plugin.

Nessus does have checks for some driver vulnerabilities (e.g. Nvidia flaw) They are generally local checks only, although a few remote ones exist (Etherleak is one that springs to mind).

You could write a Python program that invokes Intel CHIPSEC module, and generate SCAP output, instead of the normal non-SCAP output that CHIPSEC uses. But, SCAP has no OVAL definitions for BIOS/UEFI/firmware, so any BIOS results will likely only be found via full-text-search, until OVAL problem is fixed. HTH, Lee. http://firmwaresecurity.com/feed
