CVE-2024-0114
📋 TL;DR
This vulnerability in NVIDIA Hopper HGX 8-GPU systems allows attackers with administrative access to the Baseboard Management Controller (BMC) to gain administrator access to the HGX Management Controller (HMC). This affects organizations using NVIDIA Hopper HGX 8-GPU systems where BMC administrative access could be compromised. The vulnerability enables full control over the HMC management interface.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the HGX Management Controller leading to code execution on HMC, denial of service for all managed GPUs, privilege escalation to HMC administrator, disclosure of sensitive management data, and tampering with GPU configurations and workloads.
Likely Case
Unauthorized administrative access to HMC allowing configuration changes, monitoring data access, and potential disruption of GPU operations in environments where BMC credentials are compromised.
If Mitigated
Limited impact if BMC access is properly secured with strong authentication, network segmentation, and least privilege principles preventing unauthorized administrative access.
🎯 Exploit Status
Exploitation requires administrative access to the BMC first, then leveraging the vulnerability to access HMC. No public exploit code has been disclosed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to NVIDIA advisory for specific firmware versions
Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5561
Restart Required: Yes
Instructions:
1. Review NVIDIA advisory ID 5561. 2. Download updated HMC firmware from NVIDIA. 3. Apply firmware update through HMC management interface. 4. Reboot HMC to complete installation. 5. Verify firmware version after update.
🔧 Temporary Workarounds
Restrict BMC Administrative Access
allLimit administrative access to BMC to only authorized personnel using strong authentication and network controls
Network Segmentation
allIsolate BMC and HMC management interfaces on separate VLANs with strict firewall rules
🧯 If You Can't Patch
- Implement strict access controls for BMC administrative interfaces with multi-factor authentication
- Monitor BMC and HMC logs for unauthorized access attempts and implement network segmentation
🔍 How to Verify
Check if Vulnerable:
Check HMC firmware version against NVIDIA advisory. Vulnerable if running unpatched firmware.Check Version:
Check HMC web interface or CLI for firmware version (specific command varies by HMC version)Verify Fix Applied:
Verify HMC firmware version matches patched version specified in NVIDIA advisory after update.📡 Detection & Monitoring
Log Indicators:
- Unauthorized BMC login attempts followed by HMC administrative access
- HMC configuration changes from unexpected sources
- Failed authentication attempts on HMC from BMC IPs
Network Indicators:
- Unusual traffic between BMC and HMC interfaces
- Administrative connections to HMC from BMC subnet
SIEM Query:
