UEFI Secure Boot Security Feature Bypass Vulnerability
Protection mechanism failure in Windows UEFI allows an authorized attacker to bypass a security feature locally.
FAQ
What kind of security feature could be bypassed by successfully exploiting this vulnerability?
Successfully exploiting this vulnerability could bypass UEFI Secure Boot, a security feature designed to ensure that only trusted software runs when a device starts. This could allow an attacker with local administrator privileges or physical access to run untrusted code early in the boot process, before the operating system’s protections are active.

Multiple Microsoft-sigend UEFI SHIM bootloaders are vulnerable to SecureBoot bypass. An attacker with administrative privileges or the ability to modify the boot process could use one of the vulnerable shim bootloaders to bypass Secure Boot protections and execute arbitrary code before the operating system loads. Specific UEFI DBX update is required to block these vulnerable boot loaders.
