CVE-2023-47841: Missing Authorization Vulnerability in Analytify - Exploiting Incorrectly Configured Access Control Security Levels

In this post, we will discuss the details around CVE-2023-47841, which is a Missing Authorization vulnerability in Analytify. This vulnerability specifically affects Analytify versions n/a through 5.1.9 and allows attackers to exploit incorrectly configured access control security levels. Additionally, we will provide code snippets and links to original references.

Background

Analytify (https://analytify.io) is a popular analytics plugin for WordPress that provides users with detailed information about their site's performance, traffic, and user behavior. However, due to a vulnerability discovered in Analytify versions n/a through 5.1.1, the plugin can potentially expose sensitive data to unauthorized users.

Vulnerability Details

CVE-2023-47841 outlines a missing authorization vulnerability in Analytify that arises from incorrect access control configurations. Specifically, this vulnerability allows an attacker to bypass intended access control restrictions and execute unauthorized actions or access sensitive information.

In Analytify, the authorization process consists of checking if a logged-in user has the necessary capabilities to perform specific tasks, such as viewing reports or changing settings. However, due to the missing authorization vulnerability, an attacker can potentially send requests directly to the server, bypassing the frontend authorization checks and gaining unauthorized access to the restricted resources.

The following code snippet demonstrates this vulnerability

function analytify_get_ajax_data() {
     // Missing authorization check here
     ...
     $requestData = $_POST['requestData'];
     ...
}

In this example, the analytify_get_ajax_data() function processes user data obtained through a POST request without checking the user's authorization. As a result, an attacker can potentially craft a malicious POST request, potentially accessing sensitive data or modifying the Analytify configuration without proper permissions.

Mitigation

To mitigate this vulnerability, developers should add proper authorization checks to all functions that handle user input or sensitive data. For example, you can use the following code to check if the current user is authorized to perform a specific action:

function analytify_get_ajax_data() {
    if ( !current_user_can('manage_options') ) {
        wp_die( __('You do not have sufficient permissions to access this page.') );
    }
    ...
    $requestData = $_POST['requestData'];
    ...
}

With this additional authorization check, an attacker will not be able to bypass the intended access control restrictions.

Affected Versions

This issue affects Analytify versions n/a through 5.1.1.

Exploit

No known exploits for this vulnerability are currently available. However, as a precaution, we recommend updating to the latest version of Analytify to ensure the highest level of security.

Conclusion

CVE-2023-47841 highlights the importance of proper access control measures and the need for thorough authorization checks when building secure applications. By patching this vulnerability and staying informed about potential security issues, you can help protect your site against unauthorized access.
