CVE-2023-5329 - Vulnerable Field Logic DataCube4 Web API Authentication Bypass Exploit

A recently discovered vulnerability, classified as problematic and identified as CVE-2023-5329, affects Field Logic's DataCube4 software versions up to 20231001. This vulnerability is specifically present in an unknown portion of the code within the /api/ file of the Web API component. Exploiting this vulnerability can result in improper authentication and unauthorized access. The vulnerability has been publicly disclosed, and threat actors are likely to exploit it. It has been assigned the identifier VDB-241030.

Description

The improper authentication vulnerability found in Field Logic DataCube4's Web API component can be exploited through manipulative techniques. To exploit this vulnerability, an attacker requires minimal access and privileges to the target system. The attacker can initially probe the Web API component and then manipulate the authentication mechanism to bypass security measures and gain unauthorized access to the system.

Code Snippet

This code snippet demonstrates a possible way to bypass authentication by exploiting the CVE-2023-5329 vulnerability in the Field Logic DataCube4 Web API:

import requests

url = 'http://target.url/api/';
data = {
    'auth_token': '',        # Empty authentication token
    'action': 'sensitive_data_request'
}

response = requests.post(url, data=data)
if response.status_code == 200:
    print('Authentication Bypass Successful!')
    # Insert exploit code for unauthorized access here
else:
    print('Exploit Failed.')

The above code snippet shows how an attacker can potentially use an empty authentication token to exploit the vulnerability and bypass the authentication mechanism in Field Logic DataCube4 Web API.
