Discussion

AN Guestbook 'country' Parameter HTML Injection Vulnerability

AN 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 context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

Versions prior to AN Guestbook 0.7.7 are vulnerable.
