CVE-2023-31033
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA DGX A100 BMC contains a vulnerability where a user may cause a missing authentication issue for a critical function by an adjacent network . A successful exploit of this vulnerability may lead to escalation of privileges, code execution, denial of service, information disclosure, and data tampering.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe NVIDIA DGX A100 BMC has a missing authentication vulnerability for a critical function that can be exploited by an attacker on the adjacent network segment. This allows unauthorized access to the Baseboard Management Controller, which manages server hardware independently of the main OS, potentially enabling the listed impacts.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the hardware modelCheck if the system is an NVIDIA DGX A100 by reviewing system inventory, hardware labels, or BMC system information pageAffected if The system is not a DGX A100 (this CVE does not apply)
-
Determine BMC firmware versionAccess the BMC web interface or use IPMI commands to retrieve the BMC firmware version. Compare the installed version against 00.22.05Affected if The BMC firmware version is lower than 00.22.05
-
Verify BMC network accessibilityReview network configuration to determine if the BMC management interface is exposed to adjacent network segments or untrusted networksAffected if The BMC is reachable from an adjacent (non-management) network segment
The environment is affected if it is a DGX A100 system with BMC firmware version below 00.22.05 and the BMC interface is accessible from an adjacent network segment.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped00.22.05
Apply the NVIDIA firmware update for the DGX A100 BMC when available, and restrict network access to the BMC management interface to trusted networks or dedicated management VLANs.
DGX A100 BMC firmware 00.22.05 or later
- Check current BMC firmware version on the DGX A100 using the BMC web interface or IPMI command: ipmitool -I lanplus -H <bmc_ip> -U <user> -P <pass> fru print
- Navigate to NVIDIA's support portal at nvidia.custhelp.com and download DGX A100 firmware version 00.22.05 or later
- Access the BMC web interface and navigate to the firmware update section
- Upload and apply the firmware update following NVIDIA's documented update procedure
- Verify the firmware has been successfully applied by checking the BMC firmware version again
- Reboot the BMC if required by the update procedure
