CVE-2023-25534

Privileged adjacent code execution via improper IPMI validation

Published Sep 20, 2023 · Updated Sep 24, 2024

Improper input validation in NVIDIA DGX H100 BMC before 23.08.18 allows remote authenticated users to execute code through IPMI. NVIDIA identifies IPMI as the affected component but has not disclosed the input, handler, or validation operation that fails. Exploitation requires high privileges and adjacent-network access, and it can also interrupt BMC service, disclose data, alter data, or elevate privileges.
