MSI Accidentally Breaks Secure Boot for Hundreds of Motherboards 59

Over 290 MSI motherboards are reportedly affected by an insecure default UEFI Secure Boot setting that allows any operating system image to run regardless of whether it has a wrong or missing signature. From a report: This discovery comes from a Polish security researcher named Dawid Potocki, who claims that he did not receive a response despite his efforts to contact MSI and inform them about the issue. The issue, according to Potocki, impacts many Intel and AMD-based MSI motherboards that use a recent firmware version, affecting even brand-new MSI motherboard models.

        Secureboot has had a huge effect on security and is very much beneficial. I'm old enough to remember when rootkits were one of the most common forms of malware. Attack the early boot process, make it impossible for anti-virus software to remove them. Secureboot made them mostly go away because they no longer work.

    • But it could lead to a proliferation of hobbyist operating systems! The horror!

    • This sounds like a feature, not a bug...

      Not sure why you think you're smart, the feature is security, the bug is you not RTFM and realising it is entirely within your control to disable it allowing you to install whatever you want.

      • The feature is control, not security. The main goal of UEFI is to stop people from installing other things than the manufacturer wants. Especially it hinders people in installing a more secure operating system.

          You mean a more secure system like Linux, many flavours of which have been cross signed so you never even need to touch secure boot? Or a more secure OS like whatever the fuck you like because secure boot gives you the control you need to install your own keys.

          You're mistake "lack of a control" with "not having a clue and not RTFM". All you do is look silly. Stop spreading FUD and go learn to install whatever OS you want. Or just disable secure boot completely. It's all up to you, in your control.

    I once bought a bunch of MSI gear for the quality capacitors.

    I never bought any again because of the firmware.

    Gigabyte seems quite solid though not many slots on the lower end. ASUS half way on firmware with lots of slots. Tyan if you're made of money. Supermicro if you can figure out what the hay is going on with spyware situation, maybe.

      LOL! I could repeat your post except replace MSI with Gigabyte and Gigabyte with ASUS. I've sworn off Gigabyte. I've RMA'd two motherboards due to bioses self destructing. Their ability to switch bioses to a backup is flaky at best and non-functional from a flashing point of view at worse, and even now I still have an X470 board that will randomly when the moon phase is just right decide ...

Since the new firmware had a valid checksum, but was wrong for that motherboard, the "Dual BIOS" feature wouldn't work and the board was dead. I fixed it by de-soldering and swapping the firmware chips. I never dared to apply another update.

        • Mine had a socketed secondary chip, which didn't help because if you booted from the secondary chip there was (at the time) no way to flash the primary chip. The entire Dual BIOS implementation was always incredibly useless.

    • I used to only purchase Tyan board for the many builds I did for people back in the late 90'/early 2000s until they stopped making consumer boards. They were the best motherboards back then and priced mostly the same as other brands. I still have a few of those Trinity and Tiger boards laying around and they still work.

      Well, ideally, it's a choice.

      You can disable SecureBoot to boot your own compiled kernel.

      You can leave it enabled but put your own keys, to let you compile your kernel, potentially do it in a way that keeps the private signing key elsewhere.

      You can leave it at defaults and boot *most* things people would want to boot (Windows, RedHat, Centos, Rocky, Alma, Oracle Linux, Fedora, Ubuntu, Suse, LEAP, probably more).

      If something hypothetically tries to insert itself between your kernel and the platform, then it will hopefully work to mitigate that.

      It's not. The owner is in full control, always have been. The sky didn't fall. Linux didn't stop working, and basically everything the anti-secure boot FUD spreaders have said has simply not happened.

      The defect here is that the feature for those people who *want* to use it, doesn't work as intended.

      Shame on whomever modded you up.

      • Clearly you don't remember how Microsoft broke it the very first week, and aren't aware that it still doesn't work on numerous devices in the wild. Sure, the sky didn't fall, but it's disingenuous to say the things the "FUD spreaders" said would happen didn't, because every single one of their predictions absolutely did come true, if not on the scale or for the duration of time they said it would.

        To be fair, it did come to pass, but not significantly on x86. The Surface RT did not actually allow SecureBoot disable.

        Surface Pro default doesn't allow 3rd party OSes at all, but does allow you to enable 3rd party. It does also permit disabling SecureBoot.

        So there is still room to worry that devices will exist that use this to prevent non-Microsoft OSes, but so far MS hasn't gone that far on x86 devices...

        • As part of Microsoft's Designed for Windows certification requirements a system *must* allow both secure boot to be disabled, and custom keys to be installed. This is the case with the Surface Pro as well. Expecting a user to install an OS without ever touching a UEFI settings is a fantasy as they will need to in many cases enable booting from external media in the first place.

      SecureBoot is an option. You can enable and disable it at will, even on PCs that come shipped with Windows. Disable it and Windows will refuse to do some things, but you can, and always could, install whatever the heck you wanted on it.

      I don't mind UEFI compared to legacy BIOS, it solves a lot of problems. It's like GPT is a big leap over MBR.

      Please don't confuse EUFI with secure boot. Secure boot just happens to be a feature that can (usually) be turned off if you don't need it.

        I long thought there were absolutely no advantages to running UEFI with Linux, but recently (yeah, took me a long time) I discovered you can upgrade BIOS version directly from Linux in UEFI mode on most systems, while it is sometimes impossible in Legacy mode (even booting from a USB key, I'm looking at you HP).

            I'm moderately proficient on Linux, and I've written device drivers and bootloaders for custom embedded system. My take on it was to do the strict minimum in the bootloader and then offload the rest of the heavy lifting to the kernel.

      Indeed, so you got whole disk encryption and you're safe. Now the question is, do you have UEFI SecureBoot enabled, or are you leaving yourself open to someone installing a rogue malware faking a boot process and passing off to windows which can then run in the background to steal your password (you know, the one you use for your precious full disk encryption). Your full disk encryption is worthless if someone can execute arbitrary code without your knowledge on your machine. You'll just hand him the keys.

        If I suspect the machine may have been compromised, I wouldn't just enter my keys and decrypt the containers. I'd be booting Linux from a USB stick and checking things out. And of course there's the possibility that the machine may have been compromised, but UEFI doesn't necessarily prevent that. You make it sound like UEFI doesn't have its own vulnerabilities.

      Popular opinions among "techy folks" are why we can't have nice things. Do you know anybody with any experience with non-x86 firmware at all? Like what was EFI competing against, or inspired by, for example? There are many nice things you will never have by sticking with old 16-bit BIOS. If you don't understand it, how can you have an opinion? But hey, that's how IT works, or doesn't, it's not just you.

And if you do need to use custom keys for some reason, it is easy to do. 1) Enter UEFI mode and select 'clear secure boot variables'. 2) Boot install CD. Install CD sets all the required keys. 3) Reboot into UEFI and select 'Enable secure boot'. Gee, that was tough, and obviously way beyond the abilities of the 'average user'.

        • Deploying custom keys are beyond the technical aptitude of the average user

          The average user is not playing with Linux systems that require deploying custom keys. The average user is installing popular Linux distributions that very much are signed and as complex to install as popping in the installation media.

          You're spreading FUD. If you're competent enough to play with custom OSes rather than popular OSes for the masses, you're competent enough to either disable secure boot or load a custom key. The average user is unaffected by this.

If you like running anything you want then use the feature that allows you to turn secure boot off, or the feature to upload keys from your other operating systems.
