DGX H100 BMC: Insufficiently Protected Credentials
CVE-2023-25531 is a critical-severity insufficiently protected credentials vulnerability in DGX H100 BMC from NVIDIA, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 23.08.07 as the first without the flaw, so updating DGX H100 BMC to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.48% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update DGX H100 BMC to 23.08.07 or a later version.
- 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 code execution, denial of service, information disclosure, and escalation of privileges.
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.).
