itsourcecode School Management System SQL Injection Vulnerability in Controller File

A SQL injection vulnerability exists in itsourcecode School Management System version 1.0, specifically within the file '/ramonsys/user/controller.php'. The issue arises because the application does not properly sanitize or validate the 'id' parameter before using it in SQL queries. This oversight allows attackers to inject malicious SQL code, potentially leading to unauthorized database access and manipulation. The vulnerability can be exploited remotely without authentication.

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 GET request to 'controller.php' with the 'id' parameter. The injected SQL payload can be crafted to exploit the time-based blind SQL injection vulnerability, such as using a payload that includes a SQL sleep command to demonstrate the injection.

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 can also help mitigate such vulnerabilities.
