CVE-2023-29061

Boot disablement via passwordless BIOS configuration

Published Nov 28, 2023 · Updated Jun 3, 2025

Missing BIOS authentication in FACSChorus 3.0 through 3.1 and 5.0 through 5.1 allows physically proximate attackers to disable workstation boot. The affected HP Z2 G5 and G9 workstations ship without a BIOS password, exposing firmware configuration that permits changes to drive boot order and BIOS pre-boot authentication. Physical presence at the workstation is required; those changes can prevent the workstation from booting but do not expose stored sensitive data or external components.
