Problems updating the Management Engine firmware on DB75EN

My Intel Desktop Board DB75EN is affected by the AMT vulnerability.

I found a firmware update here:

https://www.intel.com/content/www/us/en/support/boards-and-kits/000024181.html Intel® Active Management Technology Escalation of Privilege Advisory...

However, when I try to install it, I encounter two problems.

First: I'm running Linux -- and the firmware update utility runs on Windows only. So is there also a utility available to update the FW under Linux?

As a workaround, I created a Windows 10 Recovery Drive (on a USB stick) and copied the update to that USB stick. I then booted the PC using that USB stick and tried to run the firmware update from within that Windows Recovery (WinPE) environment. I then got the following output:

D:\EN-FW-Update\EN-FW-Update-64bit>FWUpdLcl64.exe -f ME8_5M_Production.bin -generic

Intel (R) Firmware Update Utility Version: 8.1.40.1456

Copyright (C) 2007 - 2013, Intel Corporation. All rights reserved.

Error 8743: Unknown or Unsupported Platform

Cannot locate hardware platform identification

This program cannot be run on the current platform.

Any idea why this does not work? And how to resolve it?

I am also interested in a linux update utility. I know that FWUpdLcl has builds for DOS, win32 and win64, and initially went for the DOS executable, but found it impossible to boot DOS in EFI (Heavy reliance on BIOS), and with the other two I hit the same issue mentioned above.

Can no one help me?

Also, why does the advisory page state that a "System BIOS update [is] not planned" for this board?

https://www.intel.com/content/www/us/en/support/boards-and-kits/000024181.html Intel® Active Management Technology Escalation of Privilege Advisory...

Quite disappointing, I must say. Intel bakes in some management funtion into their chipsets that turns out to be a fully open backdoor. And then, Intel does not even provide a normal BIOS update for the board to fix it. Only some obscure update utility that requires Windows to be installed on the machine...

I finally managed to fix it. See my solution in the original thread that can be found here:

To Intel: thanks a lot for your great support...

Sadly this is not a fix for me, as it is not EFI compatible.

Hi, the reason why a system BIOS update is not planned for this board is because it has been discontinued:

The firmware update utility for this board is currently available for Windows OS...I've read through your fix which looks good. Another method would be to build a WinPE disk and install the MEI driver, then run the FWUpdate tool.

I tried exactly that (WinPE) but yet again had issues booting via EFI. I finally bit the bullet, split another gpt partition of around 32gb of my drive and put Windows 10 on it. The update itself was then executed successfully and i wiped the win 10 partition (s) right after. I just find it to be bad support when Intel is involved in the Linux kernel, mesa drivers, and releases firmware blobs for Linux, but then has difficulty porting a simple update utility (which is also available for DOS).

I'm grateful for your contribution to the community for anyone needing assistance in the future with Linux. I also get your frustration surrounding linux support. The feedback has been shared with the developers.

I'm sorry but that is BS... have a look at the table below which I copied from this page:

https://www.intel.com/content/www/us/en/support/boards-and-kits/000024181.html Intel® Active Management Technology Escalation of Privilege Advisory...

ALL products in this list have been discontinued. Yet, the majority receives a BIOS update - except the DB75EN, DQ57TM and DQ57TML. For no apparent reason.

It would be very helpful if the requirement that the MEI drivers must be installed, is mentioned somewhere.

This is not mentioned on the download page:

https://downloadcenter.intel.com/download/26829/Intel-Management-Engine-Firmware-8-x-Update-for-Inte... Download Intel® Management Engine Firmware 8.x Update for Intel® Desktop Board DB75EN, DQ77KB, DQ77CP, and DQ77MK

Nor in the https://downloadmirror.intel.com/26829/eng/Intel-ME-FW-Update-EN-Readme.pdf Read Me (pdf) that can be downloaded from that page (and is included in the firmware update package/zip).

It's especially frustrating since the ME is an OS agnostic function. And the security vulnerability is therefore present regardless which OS you run. As such, I expect a patch that can be installed regardless which OS you run.

By far the easiest solution would have been if simply a BIOS update (.BIO file) would have been made available for this board -- like for all others (see my previous reply). This could then be installed during boot (F7 BIOS Flash Update option).
