Project Worlds Online Time Table Generator SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Project Worlds Online Time Table Generator version 1.0. The issue resides in the '/student/index.php' file, where the 'e' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure 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 pose a significant threat to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/student/index.php' with the 'e' parameter. Injecting a crafted SQL payload, such as one that exploits time-based blind SQL injection, can demonstrate the vulnerability. 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 further enhance security.
