Preparing to update for Intel® Management Engine Critical Firmware Update (Intel SA-00086)

Intel released a security advisory yesterday (22/11/2017) advising of vulnerabilities with their management engine firmware – which can he found here

The reason why this is concerning for corporate customers is that basically every PC, Server and laptop that you have, most likely will be exposed, as the vast majority of corporate level hardware contains this hardware.

Intel has provided a detection tool available at https://downloadcenter.intel.com/download/27150. Contained within is a couple of applications, the GUI version will probably be handy for those orgs with only a handful of makes and models – where-as the command line tool will be more useful for larger organisations to run and centralise results via tools such as SCCM.

 

The original page contains links for various vendors update, the downside is that there doesnt seem to be many patches as yet, as per this page (at the time of writing, all Dell entries are marked as “TBD”, where-as Lenovo lists a target date of 24/11/2017)

 

So, what can you do while waiting for the patches to be released?

  • Test your systems using the provided tool to see if they are vulnerable. Testing at least one of each make/model will give you a good idea what you will need to target
  • Setup SCCM collections ready to go, which would entail
    • A collection for each make and model (I imagine many places would have this already)
    • A series of collections which each include one/make model and the criteria “AMT Agent – Flash is NOT equal to <insert version number of patched FW – once released>” – This will enable you quickly identify machines which need to be targeted with the update
    • (Please note the above is an assumption, some vendors may patch this via a BIOS update, in which case, the BIOS version may be the identifier instead)

 

Please post a comment if there are any questions – and ill update thios post once the patches are released – if there are any gotcha’s we run into.
