Code-Projects Online Reviewer System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Online Reviewer System version 1.0. The issue resides in the file '/system/system/students/assessments/pretest/take/index.php', where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, manipulation of data, leakage of sensitive information, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP GET request to '/system/system/students/assessments/pretest/take/index.php' with an injected payload in the 'id' parameter. 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. Additionally, input validation and filtering should be implemented to ensure that user input meets expected formats, and database user permissions should be minimized to the least required.
