Intel NUC BIOS vulnerability CVE-2018-12176

There is a vulnerability (CVE-2018-12176) in the BIOS of various Intel NUCs, which can be used to manipulate the devices. Intel has published a Security Advisory.


An improper input validation in the firmware for Intel NUC kits (CVE-2018-12176) allows attackers to patch the BIOS/UEFI with unsigned updates and place arbitrary code. Embdi security researchers have developed a proof of concept to manipulate the BIOS/UEFI on various Intel NUCs (details are described here). The following screenshot shows a BIOS/UEFI message on the monitor manipulated by Embedi as part of a proof of concept.

Embedi security researchers write that you need to have access to the Intel NUC and administrative privileges for an attack. This restricts the possibility of abuse (no hacking via the Internet). But it opens up new approaches for manipulating hardware. If the attacker succeeds in gaining direct access to the devices, he could place a Trojan in the BIOS/UEFI which would also survive a new installation of the operating system.

Intel now warns in the Security Advisory INTEL-SA-00176 of the vulnerability in the following NUC systems:

  • Intel® NUC Kit NUC7CJYH
  • Intel® NUC Kit NUC8i7HNK
  • Intel® Compute Card CD1M3128MK
  • Intel® Compute Card CD1IV128MK
  • Intel® Compute Card CD1P64GK
  • Intel® NUC Kit NUC7i7DNKE
  • Intel® NUC Kit NUC7i5DNKE
