CVE-2024-0387 - Vulnerability in EDS-400/G400 Series Prior to Version 3.2 Allows Attackers to Bypass Access Controls and Hide Malicious Requests by Exploiting IP Forwarding Capabilities

In this exclusive post, we will discuss a recently discovered vulnerability, code-named CVE-2024-0387, found in the EDS-400/G400 Series prior to version 3.2. This vulnerability affects the IP forwarding capabilities, which users cannot deactivate. As a result, an attacker can exploit this weakness to send requests to the product and have it forwarded to the target. This may enable the attacker to bypass access controls or hide the source of malicious requests.

Exploit Details

The EDS-400/G400 Series is a popular set of devices that serve various networking and security purposes. The affected versions, prior to version 3.2, have a flaw with the IP forwarding capabilities. The root cause of this vulnerability is the inability for users to disable IP forwarding, which may allow attackers to exploit this weakness for their benefit.

When an attacker sends a request to the compromised device, it will subsequently be forwarded to the target, effectively bypassing any access controls in place. As a result, the attacker can perform malicious actions on the target undetected, or hide their origin from security logs.

Here is an example of a simple code snippet that showcases the potential exploitation of this vulnerability:

import requests

TARGET_IP = "10...1"
EXPLOIT_DEVICE_IP = "192.168.1.2"

url_to_forward = f"http://{EXPLOIT_DEVICE_IP}?attack=true";

headers = {
    "Host": TARGET_IP,
    "X-Forwarded-For": "127...1" # Hiding the source of malicious request
}

response = requests.get(url_to_forward, headers=headers)

print(response.text)

In this code snippet, the attacker is sending a GET request to the device utilizing the CVE-2024-0387 vulnerability, using a simple HTTP request. The X-Forwarded-For header is included to hide the actual source of the request.
