CodeAstro Student Attendance Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in CodeAstro Student Attendance Management System version 1.0. The issue resides in the file '/attendance-php/Admin/createClass.php?action=edit', where the 'Id' 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 SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a GET request to '/attendance-php/Admin/createClass.php?action=edit' with a crafted 'Id' parameter that includes malicious SQL payloads. The injection can be verified by observing the application's response or by using tools like SQLMap to automate the exploitation process.

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 the application's security.
