itsourcecode Student Information Management System SQL Injection Vulnerability in Instructor Module

A critical SQL injection vulnerability has been identified in the itsourcecode Student Information Management System version 1.0. The issue resides in the instructor module, specifically within the file '/admin/modules/instructor/index.php'. This vulnerability allows remote attackers to manipulate the 'id' parameter, injecting malicious SQL queries that could be executed by the application. The lack of proper input validation enables unauthorized access to the database, potential data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, and disruption of service, posing a significant risk to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the '/admin/modules/instructor/index.php' file with a malicious payload in the 'id' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
