itsourcecode Student Information Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Student Information Management System version 1.0. The issue resides in the file /admin/modules/subject/index.php, where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database. 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 crafted HTTP request to the /admin/modules/subject/index.php endpoint, including a malicious payload in the 'id' parameter. This can be done using tools like sqlmap, which automate the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to implement input validation and sanitization for the 'id' parameter to prevent SQL injection. Additionally, using prepared statements and parameterized queries can help mitigate this vulnerability. Regular security audits and minimizing database user permissions are also advisable.
