SB2021021013 - Multiple vulnerabilities in Intel Server Boards, Server Systems and Compute Modules

Description

This security bulletin contains information about 5 vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2020-12373)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the BMC firmware for some Intel(R) Server Boards, Server Systems and Compute Modules before version 2.47. A local privileged user can  trigger memory corruption and execute arbitrary code on the target system with elevated privileges.

2) Improper input validation (CVE-ID: CVE-2020-12377)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a improper input validation in the BMC firmware for some Intel(R) Server Boards, Server Systems and Compute Modules before version 2.47. A local privileged user can  execute arbitrary code on the target system with elevated privileges.

3) Out-of-bounds read (CVE-ID: CVE-2020-12380)

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

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the BMC firmware for some Intel(R) Server Boards, Server Systems and Compute Modules before version 2.47. A local user can trigger out-of-bounds read error and escalate privileges on the system.

4) Heap-based buffer overflow (CVE-ID: CVE-2020-12375)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the BMC firmware for some Intel(R) Server Boards, Server Systems and Compute Modules before version 2.47. A local user can a heap-based buffer overflow and execute arbitrary code on the target system with elevated privileges.

5) Use of hard-coded cryptographic key (CVE-ID: CVE-2020-12376)

CWE-ID: CWE-321 - Use of Hard-coded Cryptographic Key

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

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

The vulnerability exists due to usage of a hard-coded key in the BMC firmware for some Intel(R) Server Boards, Server Systems and Compute Modules before version 2.47.A local user can gain access to sensitive information on the system.
