itsourcecode Student Management System SQL Injection Vulnerability in list_report.php

A SQL injection vulnerability exists in the itsourcecode Student Management System version 1.0, specifically within the list_report.php file. The issue arises from the application's failure to properly sanitize the 'sy' parameter, allowing attackers to inject malicious SQL code. 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 result in unauthorized data access, data leakage, data tampering, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to list_report.php with the 'sy' parameter. The injection can be crafted to exploit time-based blind SQL injection techniques, such as using a payload that includes a SQL injection that causes the database to pause execution (e.g., using the SLEEP function).

Remediation

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