CVE-ID: CVE-2020-8672

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in in BIOS firmware for 8th, 9th Generation Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 Series Processors. A local user can trigger out-of-bounds read error and read contents of memory on the system.

2) Buffer overflow

EUVDB-ID: #VU46551

Risk: Medium

CVSSv3.1: 7.3 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-14557

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in BIOS firmware for 8th, 9th, 10th Generation Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 & 5000 Series Processors. A remote authenticated user on the local network can send specially crafted traffic to the system, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Intel recommends that users of above Intel® products update to the latest BIOS version provided by the system manufacturer that addresses these issues.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU46552

Risk: Medium

CVSSv3.1: 7.3 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-14558

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to execute arbitrary code on the system.

The vulnerability exists due to application does not properly impose security restrictions, which leads to security restrictions bypass and privilege escalation in BIOS firmware for 8th, 9th, 10th Generation Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 & 5000 Series Processors. A remote user on the local network can send specially crafted data to the system and execute arbitrary code.
