CVE-2023-31008

Local code execution via undisclosed IPMI validation flaw

Published Sep 20, 2023 · Updated Sep 24, 2024

Improper input validation in NVIDIA DGX H100 BMC before 23.08.18 allows local users to execute code through IPMI. NVIDIA identifies IPMI as the affected component but has not disclosed the input, validation failure, or processing locus. A low-privileged local account is required; successful exploitation can execute code, escalate privileges, disclose information, or interrupt the BMC service.
