OpenEMR Vulnerable to SQL Injection via Unsanitized Variables in MedEx Recall/Reminder Processing

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, several variables in the MedEx recall/reminder processing code are concatenated directly into SQL queries without parameterization or type casting, enabling SQL injection. Version 8.0.0.3 contains a patch.
