itsourcecode Student Management System SQL Injection Vulnerability in new_school_year.php

A SQL injection vulnerability exists in the itsourcecode Student Management System version 1.0, specifically within the new_school_year.php file. The issue arises from the application's failure to properly sanitize the 'sy' parameter, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries. This could lead to unauthorized data access, data modification, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'new_school_year.php' with the 'sy' parameter. The injected SQL payload can exploit the time-based blind SQL injection vulnerability by using a crafted SQL injection payload that, for example, includes a time delay command such as SLEEP.

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.
