Executive Summary

This vulnerability affects the WordPress plugin 'Advanced Customized Prompts' version 1.0.1 or below. It allows unauthenticated attackers to log in as any registered user, including administrators, or create new arbitrary accounts without verifying passwords. This happens because the plugin does not properly validate passwords before issuing authenticated sessions for provided email addresses in an unauthenticated action.

Detection Guidance

Check if the WordPress plugin 'Advanced Customized Prompts' version 1.0.1 or below is installed. Inspect network traffic for unauthenticated login or account creation requests to /wp-admin/admin-ajax.php or similar endpoints. Look for suspicious sessions initiated without proper authentication.

Impact Analysis

Unauthenticated attackers can take over any account, including administrator accounts, or create new accounts with elevated privileges. This could lead to complete control over the WordPress site, data theft, unauthorized modifications, or disruption of services.

Compliance Impact

This vulnerability allows unauthenticated attackers to gain administrative access or create arbitrary accounts, which could lead to unauthorized access to sensitive user data. This may violate GDPR's data protection requirements and HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

Immediately update the 'Advanced Customized Prompts' plugin to the latest version if available. If no update exists, disable or uninstall the plugin. Review user accounts for unauthorized access or new accounts. Implement strong password policies and enable multi-factor authentication.
