CVE-2017-3754
This could enable an attacker with physical or administrative access to a system to be able to flash the BIOS with an arbitrary image and potentially run malicious BIOS code.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
Description
Some Lenovo brand notebook systems do not have write protections properly configured in the system BIOS. This could enable an attacker with physical or administrative access to a system to be able to flash the BIOS with an arbitrary image and potentially run malicious BIOS code.
