前几天FD上公布了一个vbb的xss: http://seclists.org/fulldisclosure/2008/Jun/0181.html,这个bug比较有意思:
admincp/index.php?redirect=data:text/html;base64,PHNjcmlwdD5hbGVydCgnWFNTJyk8L3NjcmlwdD4K
代码:admincp/index.php 98-107
if (!empty($vbulletin->GPC['redirect']))
{
require_once(DIR . '/includes/functions_login.php');
$redirect = htmlspecialchars_uni(fetch_replaced_session_url($vbulletin->GPC['redirect']));
print_cp_header($vbphrase['redirecting_please_wait'], '', "<meta http-equiv=\"Refresh\" content=\"0; URL=$redirect\" />");
echo "<p> </p><blockquote><p>$vbphrase[redirecting_please_wait]</p></blockquote>";
print_cp_footer();
exit;
}
http-equiv里的url使用data:text/html 实现xss。
在firefox官方的资料:http://www.mozilla.org/quality/networking/testing/datatests.html
wiki的资料:http://en.wikipedia.org/wiki/Data:_URI_scheme
可以看得出来data:类似于javasript:,那么这个估计可以跨很多程序了,在你测试xss不要忘记了data:
data:有几个特点:
1.可以指定MIME-type如text/html
2.可以指定编码如data:;charset=UTF-8,Hello
3.firefox/ie8/Opera等支持它
