code-projects Doctor Appointment System SQL Injection

Unauthenticated SQL injection in code-projects Doctor Appointment System 1.0 exposes the `/patient/booking.php` endpoint to remote database manipulation via the unsanitized `doc_id` parameter. Attackers with network access can extract patient records, appointment data, and stored credentials, or modify database contents without any authentication. Public exploit code exists on GitHub, significantly lowering the bar for exploitation; no vendor patch has been identified at time of analysis.

SQL injection in code-projects Doctor Appointment System 1.0 permits unauthenticated remote attackers to manipulate backend database queries by supplying crafted input in the `firstname` parameter of `/contactus.php`. The flaw (CWE-89) stems from unsanitized user input concatenated directly into SQL statements, enabling data extraction or modification without any credentials. A public proof-of-concept exploit is available on GitHub, reducing the barrier for opportunistic attacks despite a moderate CVSS 4.0 score of 6.9.
