CVE-2018-12176 Intel NUC BIOS Vulnerability (Windows 10)

Intel processors have been the victim of attackers and CVE-2018-12176 Intel NUC BIOS Vulnerability is a new threat in this series. The impact of this “vulnerability” is very high which affects the denial of service, information disclosure, and escalation of privilege. The inappropriate input validation in the firmware for Intel NUC kits normally let attackers patch the UEFI/BIOS. They patch BIOS or UEFI with unsigned updates and place arbitrary code. The security researchers Embedi have evolved a proof of concept to operate the BIOS/UEFI on several Intel NUCs.

So, Embedi security researchers are with a view that for an attack, you need to have access to the Intel NUC as well as administrative rights. Furthermore, this restricts the possibility of abuse – no hacking through the Internet. However, it opens up new approaches for manipulating hardware. Hence, if the attacker succeeds in gaining direct access to the devices, he can place a Trojan in the BIOS/UEFI. However, this would also survive a new installation of the OS. As a proof of concept, Embedi provides the below-given screenshot that displays a UEFI/BIOS message on the monitor.
