CVE-2023-49857 - Missing Authorization Vulnerability Explained – Exploiting Incorrectly Configured Access Control Security Levels in Awesome Support Team’s Software

A recently identified security vulnerability, CVE-2023-49857, has left many users of the Awesome Support ticketing system exposed and concerned about their confidential information. This issue affects all versions of Awesome Support through version 6.1.7, specifically due to a missing authorization mechanism that continues to impact companies and organizations around the world.

This post will break down the exploit details, provide a code snippet to demonstrate how the vulnerability can be easily exploited, and share links to original sources that will provide you with more information on how to secure your own systems.

Exploit Details

The vulnerability lies in the fact that the Awesome Support ticketing system application does not enforce proper access control across different security levels. As a result, unauthorized users can exploit the missing authorization mechanism to gain access to sensitive information and carry out other malicious activities.

The Issue:Unauthorized access to sensitive information

A potential hacker or unauthorized user can access sensitive information about an organization's support tickets by exploiting the missing authorization mechanism. This information can be used in a variety of ways, such as initiating phishing attacks, exploiting password resets, or even impersonating support staff to gain access to other systems.

Code Snippet

The following code snippet is a simple demonstration of how the vulnerability can be exploited.

import requests

url = "https://example.com/wp-admin/admin-ajax.php";

data = {
    "action": "get_ticket",
    "id": 12345, # replace with desired ticket ID
}

response = requests.post(url, data=data)
print(response.content)

In this example, the unauthorized user sends a POST request to the targeted Awesome Support system with a specified ticket ID in the 'id' parameter. Since the access control is not thoroughly checked, the unauthorized user can view the details of the specified ticket ID.
