CVE-2025-2907: Order Delivery Date Pro Auth Bypass Flaw

CVE-2025-2907 Overview

CVE-2025-2907 is a critical Cross-Site Request Forgery (CSRF) and Authorization Bypass vulnerability affecting the Order Delivery Date Pro for WooCommerce WordPress plugin before version 12.3.1. The plugin fails to implement proper authorization and CSRF checks when importing settings, and critically lacks validation to restrict which WordPress options can be modified. This allows unauthenticated attackers to manipulate core WordPress settings, including default_user_role and users_can_register, enabling complete site takeover through administrator account registration.

Critical Impact

Unauthenticated attackers can exploit this vulnerability to modify WordPress registration settings and assign administrator privileges to new user accounts, resulting in complete site compromise.

Affected Products

• Tychesoftwares Order Delivery Date Pro for WooCommerce versions prior to 12.3.1
• WordPress installations using vulnerable plugin versions
• WooCommerce stores with Order Delivery Date Pro plugin installed

Technical Details for CVE-2025-2907

Vulnerability Analysis

This vulnerability combines two distinct security weaknesses that together create a critical attack chain. First, the plugin's settings import functionality lacks both authorization checks and CSRF protection, allowing any user (including unauthenticated visitors) to trigger the import process through a crafted request. Second, the import mechanism fails to validate whether the options being updated are limited to the plugin's own settings, allowing attackers to modify arbitrary WordPress options.

The exploitation chain enables attackers to modify the default_user_role WordPress option to administrator and set users_can_register to 1 (enabled). Once these settings are modified, an attacker can simply register a new account through the standard WordPress registration form and immediately receive administrator privileges, achieving complete site takeover.

Root Cause

The root cause is improper access control implementation in the plugin's settings import functionality. The vulnerable code path fails to:

1. Verify the user has appropriate administrative capabilities before processing import requests
2. Implement CSRF token validation to prevent cross-site attacks
3. Whitelist only plugin-specific options during the import process

This combination of missing security controls violates the principle of least privilege and allows unrestricted modification of WordPress core options through an unprotected endpoint.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft a malicious request targeting the vulnerable settings import endpoint. The attack flow proceeds as follows:

1. Attacker identifies a WordPress site running a vulnerable version of Order Delivery Date Pro plugin
2. Attacker sends a crafted POST request to the settings import endpoint with modified WordPress options
3. The plugin processes the request without verifying authorization or CSRF tokens
4. WordPress core options are modified to enable user registration with administrator as the default role
5. Attacker registers a new user account via the standard registration form
6. The new account receives administrator privileges automatically
7. Attacker has complete administrative access to the WordPress installation

The vulnerability does not require any user interaction or social engineering, making it trivially exploitable at scale.

Detection Methods for CVE-2025-2907

Indicators of Compromise

• Unexpected modifications to the default_user_role WordPress option, especially changes to administrator
• The users_can_register option being enabled without administrative action
• Suspicious POST requests to plugin settings import endpoints from external IP addresses
• New user accounts with administrator privileges that were not created by site administrators
• Unexplained changes to WordPress site settings or options table entries

Detection Strategies

• Monitor the wp_options table for unauthorized changes to default_user_role and users_can_register options
• Implement web application firewall (WAF) rules to detect and block suspicious POST requests targeting plugin import endpoints
• Review web server access logs for unusual POST requests to WooCommerce plugin administration endpoints
• Set up alerts for new administrator account creation events
• Audit plugin file integrity to detect unauthorized modifications

Monitoring Recommendations

• Enable WordPress audit logging to track all option changes and user registration events
• Configure real-time alerting for any changes to user role settings or registration configuration
• Monitor HTTP traffic patterns for high-volume POST requests targeting plugin endpoints
• Implement file integrity monitoring for WordPress core and plugin files
• Regularly review user accounts for unauthorized administrator-level access

How to Mitigate CVE-2025-2907

Immediate Actions Required

• Update Order Delivery Date Pro for WooCommerce to version 12.3.1 or later immediately
• Verify the current default_user_role setting is not set to administrator
• Confirm users_can_register is set according to your site's intended configuration
• Audit all administrator accounts and remove any unauthorized users
• Review recent user registrations for suspicious activity

Patch Information

The vulnerability has been addressed in Order Delivery Date Pro for WooCommerce version 12.3.1. Site administrators should update to this version or later through the WordPress plugin administration interface or by downloading the updated version from the official source. Additional details about this vulnerability are available in the WPScan Vulnerability Report.

Workarounds

• If immediate patching is not possible, temporarily disable the Order Delivery Date Pro for WooCommerce plugin until the update can be applied
• Implement web application firewall rules to block unauthenticated requests to the plugin's settings import functionality
• Manually disable user registration by setting users_can_register to 0 and monitoring for changes
• Restrict access to WordPress administrative endpoints at the web server level using IP whitelisting
• Consider temporarily taking the site offline if compromise is suspected until proper remediation can be completed

# Verify WordPress registration settings via WP-CLI
wp option get default_user_role
wp option get users_can_register

# Ensure registration is disabled and default role is subscriber
wp option update default_user_role subscriber
wp option update users_can_register 0

# List all administrator accounts for audit
wp user list --role=administrator --format=table

# Check plugin version
wp plugin list --name=order-delivery-date --format=table
