CodeAstro Online Classroom SQL Injection Vulnerability

A SQL injection vulnerability has been identified in CodeAstro Online Classroom version 1.0. The issue arises in the file '/OnlineClassroom/askquery.php' where the 'squeryx' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential disruption of services.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data modification 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/askquery.php' with the 'eid' parameter set to any email address and the 'squeryx' parameter injected with a crafted SQL payload. 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 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.
