Big Blue Guestbook HTML Injection Vulnerabilities

Hi friends,

Big Blue Guestbook software is prone to HTML injection attacks. This issue is exposed via the message form field in the

guestbook entry submission form.

Exploitation could permit remote attackers to persistently inject hostile HTML and script code into guestbook content. This

could allow for theft of cookie-based authentications or other attacks, such as those which misrepresent guestbook content.
