Campcodes Online Teacher Record Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Online Teacher Record Management System version 1.0. The issue resides in the file '/trms/admin/edit-subjects-detail.php', where the 'editid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions could disrupt services and pose a significant threat to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a request to the '/trms/admin/edit-subjects-detail.php' file with a crafted 'editid' parameter. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities. The injection can be verified by using payloads that, for example, delay the response time (time-based blind injection) or extract database information (such as through a UNION-based injection).

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.
