itsourcecode Student Information System SQL Injection Vulnerability

A SQL injection vulnerability exists in the itsourcecode Student Information System version 1.0, specifically within the '/course_edit1.php' file. The issue arises from inadequate input validation of the 'id' parameter, allowing attackers to inject malicious SQL queries after logging in with valid credentials. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential service disruption.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data modification, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log into the application with valid credentials. Once authenticated, send a POST request to '/course_edit1.php' with the 'id' parameter manipulated to include a crafted SQL payload. The application’s response can be analyzed to confirm the successful exploitation of the SQL injection.

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 enhance overall application security.
