Fantastic GuestBook HTML-injection Vulnerabilities

Fantastic GuestBook is prone to multiple HTML-injection vulnerabilities because it fails to properly sanitize user-supplied input before using it in dynamically generated content. Attacker-supplied HTML and script code would execute in the context of the affected website, potentially allowing an attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible. If a malicious people go into the sign in form and put in the fields First Name, Last Name and Nick Name a code like this: <script>alert("XSS")</script> when you load the page http://www.example.com/[path]/guestbook.php or you read the messages of the guestbook you will se a pop-up that "say" 'XSS'.

Mitigation:

Input validation should be used to ensure that user-supplied data does not contain malicious HTML or script code.
