CodeAstro Online Classroom SQL Injection Vulnerability

A SQL injection vulnerability has been identified in CodeAstro Online Classroom version 1.0, specifically in the file '/OnlineClassroom/takeassessment2.php?exid=14'. This vulnerability arises from inadequate validation of user input in the 'Q1' parameter, allowing attackers to inject malicious SQL queries. Exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data manipulation or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/OnlineClassroom/takeassessment2.php?exid=14' with a crafted 'Q1' 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

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall security.
