Code-Projects Online Reviewer System SQL Injection Vulnerability in Login Component

A SQL injection vulnerability has been identified in Code-Projects Online Reviewer System version 1.0. The issue resides in the Login component, specifically within the '/login/index.php' file. The vulnerability arises from inadequate validation of the 'username' parameter, allowing attackers to inject malicious SQL queries. This exploitation can be performed remotely, without any authentication requirements, potentially leading to unauthorized database access, data manipulation, and disruption of services.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to access and manipulate the database. This could result in unauthorized data access, data modification or deletion, and disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/login/' endpoint with a crafted 'username' 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

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, ensuring that accounts used for database connections have only the necessary privileges.
