Executive Summary

The Rox Appointment Booking WordPress plugin before version 1.2.0 has a vulnerability where it does not check the order total or payment method against server-side pricing when creating a booking. This allows unauthenticated attackers to create bookings at any price and bypass payment restrictions.

Detection Guidance

To detect this vulnerability, check the installed version of the Rox Appointment Booking plugin. If it is below 1.2.0, the system is vulnerable. Use commands like 'wp plugin list' in WordPress or inspect the plugin files for version details.

Impact Analysis

This vulnerability could allow attackers to create bookings at arbitrary prices, bypass payment restrictions, and confirm bookings without proper payment. This may lead to financial losses or unauthorized access to services.

Compliance Impact

This vulnerability could potentially affect compliance with financial and data protection regulations by allowing unauthorized price manipulation and bypassing payment controls. For GDPR, it may impact data integrity if financial transactions are involved. For HIPAA, if patient data is processed through bookings, unauthorized access or pricing changes could violate security requirements.

Mitigation Strategies

Immediately update the Rox Appointment Booking plugin to version 1.2.0 or later. Disable the plugin if an update is not possible. Review recent bookings for suspicious transactions or unauthorized price changes.
