CodeAstro Online Classroom SQL Injection Vulnerability

A SQL injection vulnerability has been identified in CodeAstro Online Classroom version 1.0. The issue resides in the '/OnlineClassroom/studentdetails' file, where the 'deleteid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions could disrupt services and pose a significant threat to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a GET request to the '/OnlineClassroom/studentdetails.php' endpoint with a crafted 'deleteid' parameter. This parameter can be manipulated to include SQL injection payloads, such as boolean-based blind injection or error-based injection, taking advantage of the application's SQL query handling.

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 further enhance the application's security.
