Campcodes Complaint Management System SQL Injection Vulnerability in Users Index File

A critical SQL injection vulnerability has been identified in Campcodes Complaint Management System version 1.0. The issue resides in the '/users/index.php' file, where the 'username' 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 SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and in some cases, could allow for execution of administrative operations on the database or application.

Reproduction

To reproduce this vulnerability, send a POST request to '/users/index.php' with the 'username' parameter. Inject a payload that exploits the SQL injection vulnerability, such as one that uses a time-based blind SQL injection technique, where the injected SQL query includes a command to delay the response (e.g., using the SLEEP function).

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.
