Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Security features bypass

EUVDB-ID: #VU63503

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-0004

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows an attacker to bypass implemented security restrictions.

The vulnerability exists due to hardware debug modes and processor INIT setting allow to override of locks for some Intel Processors in Intel Boot Guard and Intel Trusted Execution Technology. An unauthenticated attacker with physical access to the system can bypass implemented security restrictions and escalate privileges on the system.

The vulnerability can be also exploited remotely by an authenticated attacker on the local network.

Mitigation

Install updates from vendor's website.
