itsourcecode Online Enrollment System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Online Enrollment System version 1.0. The issue arises in the file '/sms/grades/index.php?view=edit&id=1', where the 'deptid' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Such actions could disrupt services and compromise system security.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/sms/grades/controller.php?action=edit' with the 'deptid' parameter manipulated to include a crafted SQL payload. 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.
