CVE-2023-25532

Credential disclosure via IPMI protection failure

Published Sep 20, 2023 · Updated Sep 24, 2024

Insufficient credential protection in IPMI in NVIDIA DGX H100 BMC before 23.08.07 allows remote attackers to disclose credentials via adjacent network access. The IPMI implementation fails to protect credential material adequately, but NVIDIA has not published the precise vulnerable operation or code locus. Exploitation requires reachability to the BMC IPMI interface; disclosed impact is credential information disclosure without demonstrated integrity or availability effects.
