Details of CVE-2023-47241

The Missing Authorization Vulnerability, identified as CVE-2023-47241, results from failure to properly implement access control mechanisms, allowing unauthorized users to perform actions or access data that should be restricted to certain user roles or authentication levels.

This issue stems from a poorly configured Access Control List (ACL) in the CoCart - Headless Ecommerce REST API, which does not properly enforce user permissions for certain restricted endpoints.

During an internal code review, the following code snippet was identified that showcases the vulnerability:

// File: cocart-headless-ecommerce/includes/api/class-cocart-rest-controller.php
public function get_items_permissions_check( $request ) {
    $permissions = current_user_can('read');
    
    // No check for user's role or authentication level.
    if ( ! $permissions ) {
        return new WP_Error('cocart_rest_cannot_view', __('Sorry, you cannot view these details.', 'cocart-headless-ecommerce'), array('status' => rest_authorization_required_code()));
    }

    return true;
}

As evident in the above code snippet, there is no proper check for the user's role or authentication level, allowing for potential exploitation by unauthorized users.

Exploit Scenario

An attacker could exploit this vulnerability by sending a specially crafted HTTP request to the affected endpoint, bypassing the incomplete access control checks, and gaining unauthorized access to privileged data or actions. This could lead to a range of outcomes, including data leakage, unauthorized modifications, and control over the affected CoCart - Headless Ecommerce installation.

Remediating the Vulnerability

CoCart Headless, LLC has been alerted to this vulnerability, and a fix is expected to be released in version 3.11.3 or later. Users are advised to update their CoCart - Headless Ecommerce installations as soon as this updated version becomes available.

In the meantime, administrators can implement additional access controls on the server hosting the affected CoCart - Headless Ecommerce installation or temporarily restrict access to sensitive endpoints until the issue is fully resolved.

Conclusion

CVE-2023-47241 is a critical MISSING Authorization Vulnerability in CoCart Headless, LLC CoCart - Headless Ecommerce that may allow unauthorized users to bypass access control mechanisms and exploit sensitive information and actions. It is essential that users of the affected software take immediate steps to update their installations as soon as a patch becomes available or implement additional access control mechanisms to mitigate the impact of this vulnerability.
