KiviCare Clinic & Patient Management System (EHR) <= 3.6.4 - SQL Injection

ID: CVE-2024-11728

Severity: high

Author: samogod,s4e-io

Tags: cve,cve2024,wp,wordpress,wp-plugin,sqli,kivicare-clinic-management-system

Description

Section titled “Description”

The KiviCare Clinic & Patient Management System (EHR) plugin for WordPress is vulnerable to SQL Injection via the ‘visit_type[service_id]’ parameter of the tax_calculated_data AJAX action in all versions up to, and including, 3.6.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
