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 · unedited
NVIDIA DGX H100 BMC contains a vulnerability in IPMI, where an attacker may cause improper input validation. A successful exploit of this vulnerability may lead to escalation of privileges, information disclosure, and denial of service.

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 confidence

NVIDIA DGX H100 BMC contains an improper input validation vulnerability in the IPMI protocol. Attackers with authenticated access to IPMI may send specially crafted input that bypasses validation checks, potentially allowing privilege escalation, unauthorized information access through the BMC's out-of-band management interface, or denial of service via malformed IPMI commands.

MitigationIsolate BMC/IPMI management interfaces on restricted networks, enforce strong authentication for IPMI access, and apply NVIDIA firmware updates for the DGX H100 BMC when available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm DGX H100 system model
    Identify the hardware model of the system - verify it is an NVIDIA DGX H100 server
    Affected if The system is not a DGX H100, this CVE does not apply
  2. Check BMC firmware version
    Access the BMC web interface or use IPMI commands to retrieve the current BMC firmware version
    Affected if The installed BMC firmware version is lower than 23.08.18
  3. Verify IPMI is enabled
    Check if the IPMI interface is active on the BMC - this can be done via BMC web UI or IPMItool command 'ipmitool -I lanplus -H <bmc_ip> mc info'
    Affected if IPMI is disabled on the BMC, the vulnerability cannot be exploited
  4. Assess IPMI network exposure
    Determine if the IPMI management interface is reachable from network segments outside of a restricted management network
    Affected if IPMI is exposed to untrusted networks, making it accessible for an attacker with authenticated access to exploit the flaw

A system is affected if it is a DGX H100 with BMC firmware version below 23.08.18 and has IPMI enabled and accessible, even from restricted networks, since authenticated attackers could exploit the validation bypass.

Upgrade available Upgrade to 23.08.18 or later
Fixed in 23.08.18
Interim mitigation

Isolate BMC/IPMI management interfaces on restricted networks, enforce strong authentication for IPMI access, and apply NVIDIA firmware updates for the DGX H100 BMC when available.

Recommended fix High confidence

NVIDIA DGX H100 BMC Firmware version 23.08.18 or later

  1. Verify current DGX H100 BMC firmware version via IPMI or NVIDIA CLI tools (e.g., nvidia-smi or BMC web interface)
  2. Download the NVIDIA DGX H100 firmware update package version 23.08.18 or later from the NVIDIA Enterprise Support portal (enterprise.nvidia.com)
  3. Review the firmware update release notes for any specific prerequisites or procedures
  4. Apply the firmware update following NVIDIA's documented BMC firmware update process, typically via the BMC web interface or IPMI firmware update command
  5. After update completes, verify the new firmware version is 23.08.18 or later
  6. Restart BMC services if required by the update procedure
  7. Confirm the IPMI service is operational and the vulnerability is resolved
Caveat Firmware updates to BMC components typically require planned downtime; ensure proper backup of BMC configuration and follow NVIDIA's update procedure to avoid bricking the BMC
