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 resides in the Parameter Handler component, specifically within the file '/enrollment/index.php?view=edit&id=3'. The vulnerability is caused by inadequate validation of the 'deptid' parameter, allowing remote attackers to inject malicious SQL queries. This exploitation could lead 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 database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/sms/enrollment/controller.php?action=edit' with the 'deptid' parameter set to '3'. Include a payload that exploits the SQL injection, such as a time-based blind injection that uses the SQL 'SLEEP' function to demonstrate the vulnerability.

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.
