CVE-2025-47585

Executive Summary

CVE-2025-47585 is a Missing Authorization vulnerability in the Booking and Rental Manager for WooCommerce WordPress plugin by Magepeopleteam, affecting versions up to and including 2.3.8. This flaw allows unauthenticated attackers to access backend functionality that should be restricted by Access Control Lists (ACLs). The vulnerability has a CVSS score of 6.5 (Medium) and currently has no known public exploit or patch. Given the WordPress ecosystem context, this plugin is widely used for managing bookings and rentals, making it a high-value target for automated scanning and exploitation.

Supply Chain & Package Security

This vulnerability resides in a WordPress plugin distributed via the official WordPress plugin repository. The plugin is not an NPM, PyPI, Go, or Ruby package, but it is part of the WordPress supply chain. Users are advised to monitor the plugin’s update channel and consider disabling the plugin until a patch is released.

CVSS Breakdown & Threat Level

• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
• Base Score: 6.5 (Medium)
• Attack Vector: Network (AV:N)
• Attack Complexity: Low (AC:L)
• Privileges Required: None (PR:N)
• User Interaction: None (UI:N)
• Scope: Unchanged (S:U)
• Confidentiality Impact: Low (C:L)
• Integrity Impact: Low (I:L)
• Availability Impact: None (A:N)

Threat Level: Medium. The vulnerability allows unauthorized access to functionality but does not directly lead to full site compromise. However, combined with other vulnerabilities, it could be chained for privilege escalation or data exfiltration.

Deep Dive & Mechanics

The vulnerability stems from missing authorization checks in the plugin’s AJAX handlers and REST endpoints. The plugin fails to verify user capabilities before executing sensitive operations such as:

• Viewing or modifying booking data
• Accessing admin-only settings
• Triggering email notifications or payment processing

The affected code likely uses wp_ajax_nopriv_* hooks without proper capability checks, allowing unauthenticated users to call these functions. The plugin’s version <= 2.3.8 does not implement nonce verification or user role validation for these endpoints.

Vulnerable vs. Patched Code

Since no patch is available, the vulnerable code pattern is described below. A hypothetical patched version would include proper capability checks.

Vulnerable Code (hypothetical):

add_action('wp_ajax_nopriv_booking_manager_get_data', 'handle_get_data');
function handle_get_data() {
    // No capability check
    $data = get_option('booking_manager_data');
    wp_send_json_success($data);
}

Patched Code (hypothetical):

add_action('wp_ajax_nopriv_booking_manager_get_data', 'handle_get_data');
function handle_get_data() {
    if (!current_user_can('manage_options')) {
        wp_die('Unauthorized', 403);
    }
    $data = get_option('booking_manager_data');
    wp_send_json_success($data);
}

Exploitation & Lab Setup

Red Team

Prerequisites:

• Target WordPress site with Booking and Rental Manager plugin <= 2.3.8
• No authentication required

Exploitation Steps:

1. Identify vulnerable endpoints by analyzing the plugin’s JavaScript files for AJAX actions.
2. Send a crafted request to the vulnerable endpoint:

curl -X POST "https://target.com/wp-admin/admin-ajax.php" \
  -d "action=booking_manager_get_data&nonce=123" \
  -H "User-Agent: Mozilla/5.0"

3. If the endpoint returns sensitive data without authentication, the vulnerability is confirmed.

No public exploit code is available.

Blue Team

Detection:

• Monitor for unusual AJAX requests to admin-ajax.php with actions related to the plugin (e.g., booking_manager_*).
• Look for requests from unauthenticated users to endpoints that should require admin privileges.

Hunting Query (Splunk):

index=web sourcetype=access_combined
| search uri="/wp-admin/admin-ajax.php" action=booking_manager_*
| eval authenticated=if(cookie="*wordpress_logged_in*", "yes", "no")
| where authenticated="no"
| stats count by src_ip, uri, action

Indicators of Compromise (IOCs)

• Network IOCs:

  • POST requests to /wp-admin/admin-ajax.php with action=booking_manager_* parameters from unauthenticated sources.
  • Unusual HTTP response codes (200 OK) for sensitive data without authentication.

• File IOCs:

  • Plugin file: /wp-content/plugins/booking-and-rental-manager-for-woocommerce/
  • Suspicious log entries in WordPress debug log: PHP Notice: Undefined index: nonce in ...

• Behavioral IOCs:

  • Sudden increase in failed login attempts (if used for brute force).
  • Unauthorized changes to booking data or settings.

Remediation & Mitigation

Immediate Actions:

1. Disable the plugin until a patch is released.
2. Implement a Web Application Firewall (WAF) rule to block unauthenticated requests to admin-ajax.php with action=booking_manager_*.
3. Monitor logs for exploitation attempts.

Long-term Fix:

• Apply the vendor patch when available.
• If no patch is forthcoming, consider replacing the plugin with an alternative.

Workaround:

• Add a custom function to your theme’s functions.php to enforce capability checks:

add_action('init', function() {
    if (defined('DOING_AJAX') && DOING_AJAX) {
        $action = $_REQUEST['action'] ?? '';
        if (strpos($action, 'booking_manager_') === 0 && !current_user_can('manage_options')) {
            wp_die('Unauthorized', 403);
        }
    }
});
