A newly discovered security vulnerability, tagged as CVE-2023-47780, affects the popular EasyAzon WordPress plugin. The vulnerability is a result of Missing Authorization, allowing bad actors to exploit Incorrectly Configured Access Control Security Levels. This post serves as an in-depth review of the exploit, including details on the code snippet involved, original references, and an overview of the potential risks associated with this vulnerability.

Affected Versions

This Missing Authorization vulnerability affects the EasyAzon plugin versions from (not available) to 5.1..

Exploit Details

The vulnerability stems from EasyAzon's omission of proper authorization checks, giving malicious users an opportunity to exploit the application's access controls. This issue occurs when the plugin's configuration isn't set up correctly, potentially granting unauthorized parties access to sensitive data and functionality.

Here's a code snippet showing the affected part of EasyAzon's source code

// easyazon.php

function easyazon_get_actions() {
  $action = isset($_REQUEST['easyazon_action']) ? $_REQUEST['easyazon_action'] : false;

  if($action) {
    switch($action) {
      case 'easyazon-get-amazon-data':
        $data = easyazon_get_amazon_data(); // Missing Authorization Check
        break;
      ...
    }
  }
}

As seen from the code snippet above, the function easyazon_get_actions() does not perform necessary authorization checks before executing sensitive actions such as easyazon-get-amazon-data.

Potential Impacts

Exploiting this vulnerability could lead to unauthorized access to sensitive information and critical features within the EasyAzon plugin and the WordPress installation. Access to such features and data provides an attacker with the ability to manipulate site content, alter settings, view sensitive information, or even execute further malicious actions.

Recommendations

To mitigate this vulnerability, it is important to upgrade the EasyAzon plugin to the latest version, where the security issue has been resolved. Additionally, it's crucial to regularly update all WordPress plugins and themes, and use strong authentication methods to prevent unauthorized access.
