itsourcecode Web-Based Internet Laboratory Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Web-Based Internet Laboratory Management System version 1.0. The issue resides in the file /user/controller.php, where insufficient input validation allows attackers to inject malicious SQL queries through the 'action=delete&id=1' parameter. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a request to the '/user/controller.php' file with the 'action=delete' parameter and an 'id' value that includes a crafted SQL payload. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to separate SQL code from user input, validate and filter user input to ensure it meets expected formats, minimize database user permissions, and conduct regular security audits.
