Code-Projects Simple Scheduling System SQL Injection Vulnerability in addfaculty.php

A SQL injection vulnerability has been identified in Code-Projects Simple Scheduling System version 1.0. The issue resides in the addfaculty.php file, where the falname parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the /schedulingsystem/addfaculty.php endpoint. The request must include the falname parameter, which can be crafted to inject SQL payloads. This injection takes advantage of time-based blind SQL injection techniques, such as using the SQL SLEEP function to delay the response and indicate successful exploitation.

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.
