CVE-2023-46082 - Missing Authorization Vulnerability in Cyberlord92 Broken Link Checker | Finder Allows Exploiting Incorrectly Configured Access Control Security Levels

In today's world where web applications are rapidly evolving to provide better user experiences and functionality, developers are often hard-pressed to ensure that every aspect of their application is secure. One of the critical aspects is access control and ensuring that users are granted the appropriate access to resources. The CVE-2023-46082 vulnerability has recently been identified in Cyberlord92's Broken Link Checker | Finder plugin, which might put several applications at risk of unauthorized access.

Overview

CVE-2023-46082 is a missing authorization vulnerability discovered in Cyberlord92 Broken Link Checker | Finder plugin (versions N/A through 2.4.2). This plugin is designed to help web admins and developers locate any broken links within their web applications. The vulnerability exposes sensitive application data to unauthorized users, due to improperly configured access control security levels.

Exploiting this vulnerability can lead to unauthorized access to the application's sensitive data and information. This, in turn, creates a potential risk for the privacy and security of the end users and administrators of the web application.

Exploit Details

A missing authorization vulnerability occurs when a user has access to a resource without being authenticated or authorized to view or perform specific actions on that resource. In the case of the CVE-2023-46082 exploit, unauthorized users can perform actions such as:

View, modify, or delete internal application configurations and settings.

The exploit is possible due to the mishandling of access control security levels within the plugin. By gaining unauthorized access, an attacker can potentially harvest sensitive data and disrupt the application's functionality.

Here is a sample code snippet illustrating the vulnerability

# Code snippets of Missing Authorization vulnerability in Cyberlord92 Broken Link Checker | Finder (versions N/A through 2.4.2)

# User data is fetched without validating user access level
def get_broken_links(user):
  # Missing proper access control validation
  # An attacker can bypass this using various techniques
  user_data = fetch_user_broken_links(user)
  return user_data

This code snippet demonstrates that the function used to fetch user data is exposed without proper access control.
