CVE-2017-3197

CWE-693Published: July 9, 2018· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

GIGABYTE BRIX UEFI firmware for the GB-BSi7H-6500 (version F6) and GB-BXi7-5775 (version F2) platforms does not securely implement BIOSWE, BLE, SMM_BWP, and PRx features. As a result, the BIOS is not protected from arbitrary write access and may permit modifications to the SPI flash.

Technical Analysis

CVE-2017-3197 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
