  "title": "Secure Boot Component Security Feature Bypass Vulnerability",
  "description": "\u003Cp\u003EA security feature bypass vulnerability exists when Windows Secure Boot improperly loads a boot policy that is affected by the vulnerability. An attacker who successfully exploited this vulnerability could disable code integrity checks, allowing test-signed executables and drivers to be loaded onto a target device.\u003C/p\u003E\n\u003Cp\u003ETo exploit the vulnerability, an attacker who has physical access or Administrative rights to a target device could install an affected boot policy.\u003C/p\u003E\n\u003Cp\u003EThe security update addresses the vulnerability by revoking affected boot policies in the firmware. The revocation protection level depends upon platform firmware. The Windows event channel Microsoft-Windows-Kernel-Boot may be used to determine the protection level provided. Note that an additional reboot is needed to view the event:\u003C/p\u003E\n\u003Cul\u003E\n\u003Cli\u003EWindows versions prior to Windows 10 do not log the event by default. You must enable \u201Canalytic\u201D logging for this channel prior to installation of the patch.\u003C/li\u003E\n\u003Cli\u003EWindows versions 10 and higher log the event by default. Event ID 155 indicates baseline protection. Event ID 154 indicates enhanced protection.\u003C/li\u003E\n\u003C/ul\u003E\n\u003Cp\u003EFor systems that provide baseline protection, firmware updates from your OEM may be available that upgrade systems to enhanced protection.\u003C/p\u003E",
