CVE-2023-25532 is a high-severity insufficiently protected credentials vulnerability in DGX H100 BMC from NVIDIA, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected DGX H100 BMC versions: All versions prior to 23.08.07. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Dgx H100 Firmware to 23.08.18 or a later version.
- Read the advisory on nvidia.custhelp.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
NVIDIA DGX H100 BMC contains a vulnerability in IPMI, where an attacker may cause insufficient protection of credentials. A successful exploit of this vulnerability may lead to information disclosure.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
