Code-Projects Online Appointment Booking System SQL Injection Vulnerability in Deletemanagerclinic.php

A SQL injection vulnerability has been identified in the Online Appointment Booking System version 1.0. The issue resides in the admin/deletemanagerclinic.php file, where the clinic parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, with potential consequences including unauthorized database access, data manipulation, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/deletemanagerclinic.php file with the clinic parameter. The request can include a crafted SQL payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
