Buffer overflow in Intel products - CVE-2020-12373

Vulnerability identifier: #VU50585

CSH Severity: Low

CVSS v4: 8.4 [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]

CVE-ID: CVE-2020-12373

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: No public exploit available

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.
