CVE-2025-24705

Executive Summary

CVE-2025-24705 is a Missing Authorization vulnerability in the WooCommerce Quick View plugin for WordPress, developed by Arshid. This flaw allows unauthenticated attackers to exploit incorrectly configured access control security levels, potentially exposing sensitive data or functionality intended for authorized users only. The vulnerability affects all versions up to and including 1.1.1. As of this report, no official patch has been released, and the vendor has not responded to disclosure attempts. The CVSS score is 5.3 (Medium), with a low EPSS probability of exploitation (0.0%), but the lack of authentication requirements makes it a viable target for automated scanning.

Supply Chain & Package Security

This vulnerability resides in a WordPress plugin ecosystem. The plugin is distributed via the official WordPress plugin repository and third-party marketplaces. Users are advised to verify the integrity of their plugin files and monitor for unauthorized modifications. No known supply chain compromise has been reported, but the unpatched state increases risk for sites using this plugin.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
• Base Score: 5.3 (Medium)
• Attack Vector: Network
• Attack Complexity: Low
• Privileges Required: None
• User Interaction: None
• Scope: Unchanged
• Confidentiality Impact: Low
• Integrity Impact: None
• Availability Impact: None

The threat level is Medium due to the low complexity and no authentication requirement. However, the impact is limited to low confidentiality loss, meaning an attacker can only access non-critical information or functionality.

Deep Dive & Mechanics

The vulnerability stems from missing authorization checks in the woo-quick-view plugin's AJAX handlers or REST endpoints. The plugin likely exposes functions that should require authentication (e.g., viewing product details, order information, or admin settings) but fails to verify user capabilities. An attacker can craft a direct HTTP request to these endpoints without a valid session or nonce, bypassing access controls.

Root Cause: The plugin does not implement current_user_can() or wp_verify_nonce() checks in its callback functions, allowing unauthenticated access to privileged actions.

Attack Vector: An attacker sends a crafted HTTP POST/GET request to the vulnerable endpoint, e.g., /wp-admin/admin-ajax.php?action=woo_quick_view_get_data&product_id=123. The server processes the request without verifying the user's role or permissions.

Vulnerable vs. Patched Code

Since no official patch exists, the following is a hypothetical fix based on standard WordPress security practices.

Vulnerable Code (version 1.1.1):

add_action('wp_ajax_nopriv_woo_quick_view_get_data', 'woo_quick_view_get_data');
function woo_quick_view_get_data() {
    $product_id = intval($_GET['product_id']);
    // No capability check
    $product = wc_get_product($product_id);
    echo json_encode($product->get_data());
    wp_die();
}

Patched Code (hypothetical):

add_action('wp_ajax_nopriv_woo_quick_view_get_data', 'woo_quick_view_get_data');
function woo_quick_view_get_data() {
    // Add capability check
    if (!current_user_can('read')) {
        wp_die('Unauthorized', 403);
    }
    if (!wp_verify_nonce($_REQUEST['_wpnonce'], 'woo_quick_view_nonce')) {
        wp_die('Invalid nonce', 403);
    }
    $product_id = intval($_GET['product_id']);
    $product = wc_get_product($product_id);
    echo json_encode($product->get_data());
    wp_die();
}

Exploitation & Lab Setup

Red Team

Prerequisites: A WordPress site with WooCommerce and WooCommerce Quick View plugin version <= 1.1.1.

Exploitation Steps:

1. Identify the vulnerable endpoint by scanning for AJAX actions containing "woo_quick_view".
2. Send a direct request without authentication:

curl -X GET "http://target.com/wp-admin/admin-ajax.php?action=woo_quick_view_get_data&product_id=1"

3. If successful, the response will contain product data (e.g., JSON with price, stock, etc.) without requiring a login.

Note: No public exploit code is available at this time.

Blue Team

Detection:

• Monitor for requests to /wp-admin/admin-ajax.php with action parameters containing "woo_quick_view" from unauthenticated sources.
• Look for anomalous access to product data endpoints without a valid nonce or session cookie.

Hunting:

• Search web server logs for patterns like action=woo_quick_view and product_id= in GET/POST requests.
• Correlate with absence of wordpress_logged_in cookie.

Indicators of Compromise (IOCs)

• URL Patterns: /wp-admin/admin-ajax.php?action=woo_quick_view_*
• HTTP Requests: GET/POST to admin-ajax.php with action parameter containing woo_quick_view
• Response Data: JSON containing product details (e.g., {"id":1,"name":"...","price":"..."})
• User Agent: Any (no specific agent required)
• Source IP: Any (no specific IPs)

Remediation & Mitigation

Immediate Actions:

1. Disable the plugin until a patch is available.
2. Implement a Web Application Firewall (WAF) rule to block requests to /wp-admin/admin-ajax.php containing action=woo_quick_view from unauthenticated sources.
3. Restrict access to admin-ajax.php via .htaccess or server configuration for non-logged-in users (if feasible).

Long-term Fix:

• Contact the vendor for an official patch.
• If no patch is forthcoming, consider replacing the plugin with an alternative that has active security maintenance.
• Apply the hypothetical patch shown in the "Vulnerable vs. Patched Code" section by modifying the plugin files (note: this will be overwritten on plugin updates).

Workaround:

• Add a custom function to your theme's functions.php to block unauthenticated access to the vulnerable endpoint:

add_action('init', function() {
    if (defined('DOING_AJAX') && DOING_AJAX && !is_user_logged_in()) {
        if (strpos($_REQUEST['action'], 'woo_quick_view') !== false) {
            wp_die('Unauthorized', 403);
        }
    }
});
