TUTOS is vulnerable to path disclosure, cross-site scripting, and possibly SQL injection attacks. An attacker can exploit these vulnerabilities by crafting a malicious URL and sending it to a user of the application. For example, the following URL can be used to exploit the path disclosure vulnerability: http://www.example.com/php/note/note_overview.php?id=1&sort=1&order=1. This URL will reveal the full path of the application, which can be used to further exploit the application.
