SourceCodester CampCodes School Log Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester CampCodes School Log Management System version 1.0. The issue resides in the file /admin/admin_class.php, where the 'id_no' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and potentially allow attackers to gain control over the application or its underlying system.

Reproduction

The vulnerability can be reproduced by sending a POST request to the 'ajax.php' endpoint with the 'id_no' parameter. The request must include a crafted SQL payload that exploits the application's SQL query handling. 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. 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.
