realGuestbook contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'bg_color_1', 'fs_menu', 'fc_menu', 'ff_menu', 'bg_color_2', 'fs_normal', 'fc_normal' and 'ff_normal' variables upon submission to the 'welcome_admin.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
