CVE-2023-31033

Authenticated code execution via unauthenticated critical function

Published Jan 12, 2024 · Updated Jun 3, 2025

Missing authentication in the NVIDIA DGX A100 BMC before 00.22.05 allows remote authenticated users to execute code over an adjacent network. NVIDIA identifies a critical BMC function that lacks authentication but does not disclose the function, interface, or request that reaches it. Access requires high privileges on the adjacent management network; exploitation grants elevated privileges and code execution and can disclose or alter data or interrupt service.
