Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper access control
EUVDB-ID: #VU48426
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2020-8764
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in BIOS firmware. A local administrator can bypass implemented security restrictions, gain unauthorized access to the application and escalate privileges on the target system.
MitigationInstall updates from vendor's website.
