Campcodes Online Learning Management System SQL Injection Vulnerability in Edit Student Admin File

A SQL injection vulnerability has been identified in Campcodes Online Learning Management System version 1.0. The issue resides in the admin file 'edit_student.php', where insufficient input validation of the 'cys' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without authentication, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to gain unauthorized access to the database, leak sensitive information, alter or delete data, and disrupt services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/edit_student.php' with a crafted 'cys' parameter that includes malicious SQL payloads. 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.
