CVE-2017-9457
The absence of signature validation allows an attacker with administrator privileges to flash a modified UEFI BIOS.
Does this matter?
Lower severity and a low EPSS score (0.83%). Track it; it rarely justifies an emergency change on its own.
Description
Intense PC Phoenix SecureCore UEFI firmware does not perform capsule signature validation before upgrading the system firmware. The absence of signature validation allows an attacker with administrator privileges to flash a modified UEFI BIOS.
