New Horizon Datasys Bootloaders
A flaw was found in the bootloaders, allowing an attacker to bypass or tamper with Secure Boot protections. To load and execute arbitrary code in the pre-boot stage, an attacker needs to replace the existing signed bootloader with this one, requiring access to the EFI System Partition for booting using external media. The vulnerability is related to errors in security settings, which can be exploited to bypass existing security restrictions.
