Campcodes Online Learning Management System SQL Injection Vulnerability in save_student.php

A SQL injection vulnerability has been identified in Campcodes Online Learning Management System version 1.0. The issue arises in the file /admin/save_student.php, where insufficient validation of the 'class_id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading 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 the application's database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the /admin/save_student.php endpoint with a crafted 'class_id' parameter that includes malicious SQL payloads. This injection exploits the application's SQL query handling, taking advantage of the lack of proper input sanitization.

Remediation

It is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure user input meets expected formats. Minimizing database user permissions and conducting regular security audits are also advisable.
