Re: [FD] Major Internet Explorer Vulnerability - NOT Patched

'could you share the contents of "1.php"?'
Sure:
<?php
sleep(2);
header("Location: http://www.dailymail.co.uk/robots.txt";);
?>

"I'm assuming it is a delayed re-direct to the target's domain?"
Exactly. :-)

"the cloudflare scripts"
It's been tested without them.

Kind Regards,

Thanks Zaakiy,

I'm able to get the hacked page on IE9 after changing the document mode from 
Quirks to IE9 Standards. Screenshot attached. I'm sure you could get around 
having to manually switch the document mode with the appropriate DOCTYPE set in 
the exploit html page.

David, could you share the contents of "1.php"? I'm assuming it is a delayed 
re-direct to the target's domain? I am unable to reproduce the exploit locally with the 
same code (assuming my 1.php is correct), though without the cloudflare scripts.

Thanks,
Peter

Hi David,

Nice one…great find!  And thanks Joey for confirming the bypass of 
HTTP-to-HTTPS restrictions.

I can confirm that this also affects Spartan Browser (Experimental enabled in 
about:flags in Internet Explorer 11).

I can also confirm that IE 10 is affected.

IE 9 appears to not be vulnerable. Screenshots below.

Regards,
Zaakiy Siddiqui


IE 11 Spartan - vulnerable (Windows 10)

IE 10 - vulnerable (Windows 7)

IE 9 - not vulnerable (Windows 7)

Joey thank you very much for your words.

Hi David,

"nice" is an understatement here.

I've done some testing with this one and, while there /are/ quirks, it most 
definitely works. It even bypasses standard HTTP-to-HTTPS restrictions.

As long as the page(s) being framed don't contain X-Frame-Options headers (with 
`deny` or `same-origin` values), it executes successfully. Pending the payload 
being injected, most Content Security Policies are also bypassed (by injecting 
HTML instead of JavaScript, that is).

It looks like, through this method, all viable XSS tactics are open!

Nice find!

Has this been reported to Microsoft outside (or within) this thread?
