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

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)
