ESET researchers have discovered a vulnerability that allows bypassing UEFI Secure Boot, affecting the majority of UEFI-based systems. This vulnerability, assigned CVE-2024-7344, was found in a UEFI application signed by Microsoft’s Microsoft Corporation UEFI CA 2011 third-party UEFI certificate. Exploitation of this vulnerability leads to the execution of untrusted code during system boot, enabling potential attackers to easily deploy malicious UEFI bootkits (such as Bootkitty or BlackLotus) even on systems with UEFI Secure Boot enabled, regardless of the installed operating system.
