Big Blue Guestbook Comment HTML Injection Vulnerability

Big Blue Guestbook is prone to an HTML-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would run in the browser of an unsuspecting victim in the context of the affected site, 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.
