CVE-2024-0105

8.9 HIGH

📋 TL;DR

This vulnerability in NVIDIA ConnectX firmware allows attackers with insufficient privileges to trigger improper privilege handling, potentially causing denial of service, data tampering, or information disclosure. It affects systems using vulnerable NVIDIA ConnectX network adapters. Organizations using these adapters in servers, high-performance computing, or cloud infrastructure are at risk.

💻 Affected Systems

Products:
  • NVIDIA ConnectX network adapters
Versions: Specific vulnerable firmware versions detailed in NVIDIA advisory
Operating Systems: All operating systems using affected ConnectX adapters
Default Config Vulnerable: ⚠️ Yes
Notes: Affects ConnectX adapters with vulnerable firmware versions; exact versions listed in NVIDIA advisory.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system disruption through denial of service, unauthorized data modification, and exposure of sensitive information from affected network adapters.

🟠

Likely Case

Service disruption affecting network connectivity and performance of systems using vulnerable ConnectX adapters.

🟢

If Mitigated

Minimal impact with proper network segmentation and access controls limiting exposure to trusted administrative networks.

🌐 Internet-Facing: LOW - Network adapters typically not directly internet-facing, though could be exposed through misconfigurations or compromised adjacent systems.
🏢 Internal Only: HIGH - Attackers with internal network access could exploit this to disrupt critical infrastructure, especially in data center and HPC environments.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires network access to vulnerable adapter and ability to send crafted requests; privilege escalation aspect suggests some existing access needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Firmware versions specified in NVIDIA advisory

Vendor Advisory: https://nvidia.custhelp.com/app/answers/detail/a_id/5562

Restart Required: Yes

Instructions:

1. Review NVIDIA advisory for specific affected firmware versions. 2. Download updated firmware from NVIDIA support portal. 3. Apply firmware update using NVIDIA tools (MFT or similar). 4. Reboot system to activate new firmware.

🔧 Temporary Workarounds

Network segmentation

all

Isolate ConnectX adapters to trusted administrative networks only

Access control restrictions

all

Limit administrative access to ConnectX management interfaces

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate ConnectX adapters from untrusted networks
  • Monitor for unusual network adapter behavior and implement intrusion detection for management traffic

🔍 How to Verify

Check if Vulnerable:

Check current ConnectX firmware version using 'mstflint -d <device> q' or similar NVIDIA management tools

Check Version:

mstflint -d <device> q | grep -i firmware

Verify Fix Applied:

Verify firmware version matches patched version from NVIDIA advisory using same tools

📡 Detection & Monitoring

Log Indicators:

  • Unusual firmware access attempts
  • Unexpected privilege escalation events
  • ConnectX adapter error or reset logs

Network Indicators:

  • Abnormal traffic patterns to ConnectX management interfaces
  • Unexpected firmware update attempts

SIEM Query:

source="connectx_logs" AND (event_type="privilege_escalation" OR event_type="firmware_access")
