Detailsinfo

A vulnerability, which was classified as critical, was found in Gigabyte GB-BSi7H-6500 and GB-BXi7-5775 (unknown version). This affects an unknown code block of the component BIOSWE/BLE/SMM_BWP/PRx. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The bug was discovered 03/31/2017. The weakness was shared 07/09/2018 by Alex Matrosov with Cylance as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2017-3197 since 12/05/2016. The exploitability is told to be easy. It is possible to initiate the attack remotely.
