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/search.php', where the 'searchdata' 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 pose a significant threat to the overall security of the system and its data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/trms/admin/search.php' with the 'searchdata' parameter. The request can include a payload that exploits the SQL injection vulnerability, such as a time-based blind injection payload that uses the SQL 'SLEEP' function, or a UNION-based injection payload that extracts data from the database.

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.
