Code-Projects Online Appointment Booking System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Online Appointment Booking System version 1.0. The issue resides in the '/cancelbookingpatient.php' file, where the 'appointment' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any 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, enabling attackers to manipulate database queries. This could result in unauthorized access to database information, modification or deletion of data, and in some cases, execution of administrative operations on the database server.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'cancelbookingpatient.php' with an injected SQL payload in the 'appointment' parameter. The injection can be crafted to exploit error-based SQL injection techniques, such as extracting database information using SQL injection payloads that leverage MySQL error messages.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall security.
