    Apply Windows Security Feature Bypass in Secure Boot BootHole


    Hello all!I have been attempting to patch some vulnerabilities on our network and have been experiencing some issues and was wondering if anyone had the insight to assist!When running this Powershell command, the result comes back as true:[System.Text.Encoding]::ASCII.GetStringGet-SecureBootUEFI db.bytes -match 'Microsoft Corporation UEFI CA 2011'So, given that this should not be true, I have followed these steps and everything worked as outlined by this link:https://support.microsoft.com/en-us/topic/microsoft-guidance-for-applying-secure-boot-dbx-update-e3b9e4cb-a330-b3ba-a602-15083965d9c

    Windows 8 Secure Boot Feature: Not So Secure?

    • Linux

    • Oh and OSX
    Here is a statement from a Kernal Developer at Red Hat:

    I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.

    So Linux is switching to secure boot also? Or they have to because of UEFI?
