Code-Projects Simple Scheduling System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Simple Scheduling System version 1.0. The issue resides in the file '/add.home.php', where the 'faculty' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, 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 data access, data leakage, data modification or deletion, and potentially gaining control over the application or underlying system.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/schedulingsystem/add.home.php' with the 'faculty' parameter. Injecting SQL payloads, such as boolean-based blind, error-based, or time-based blind SQL injection techniques, can exploit the vulnerability. This can be done using tools like sqlmap.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits are also advisable.
