Hogstorps Guestbook Message Post Multiple HTML Injection Vulnerabilities

Hogstorps guestbook is prone to multiple HTML-injection vulnerabilities because the application 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.

This issue affects version 2.0; other versions may also be vulnerable.
