Summary:
Intel® NUC and Intel® Compute Stick systems based on 6th Gen Intel® Core™ processors do not have DCI debug capability properly locked for BIOS only access. This would allow an attacker with physical possession of the system to potentially enable DCI from outside the BIOS.
Description:
Intel® Direct Connect Interface (DCI) provides closed chassis access to perform debug for processing OEM and OEM customer returns. DCI is was designed to be enabled only via BIOS settings. Current settings in the referenced product family BIOS may allow an attacker with physical access to the system.
If an attacker were able to gain physical access to a system and enable DCI, it is possible they may gain access to personal information. Intel views this risk as a Moderate (4.7) due to physical access and high privileges being required by an attacker.
- Moderate (4.7) CVSS:3.0/AV:P/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L
