Submit #792708: SourceCodester Clinic's Patient Management System in PHP/PDO Free Source Code V1.0 SQL Injection

During the security review of "Clinic's Patient Management System in PHP/PDO Free Source Code", TianYu Jiao discovered a critical SQL injection vulnerability in the "/new_prescription.php" file. This vulnerability stems from insufficient user input validation of the 'patient (POST)' parameter, allowing attackers to inject malicious SQL queries. Therefore, attackers can gain unauthorized access to databases, modify or delete data, and access sensitive information. Immediate remedial measures are needed to ensure system security and protect data integrity.

A SQL injection vulnerability was found in the '/new_prescription.php' file of the 'Clinic's Patient Management System in PHP/PDO Free Source Code' project. The reason for this issue is that attackers inject malicious code from the parameter 'patient (POST)' and use it directly in SQL queries without the need for appropriate cleaning or validation. This allows attackers to forge input values, thereby manipulating SQL queries and performing unauthorized operations.

Attackers can exploit this SQL injection vulnerability to achieve unauthorized database access, sensitive data leakage, data tampering, comprehensive system control, and even service interruption, posing a serious threat to system security and business continuity.
