CVE-2023-28737

Local privilege escalation via improper initialization

Published Nov 14, 2023 · Updated Aug 14, 2024

Improper initialization in Intel Aptio V UEFI Firmware Integrator Tools allows local users to escalate privileges via local access. Intel has not disclosed which tool component or resource is improperly initialized, or how that state is used during execution. A low-privilege account and local execution are required; successful exploitation crosses a security boundary and grants elevated control over confidentiality, integrity, and availability.
