Self-Executing HTML: Internet Explorer 5.5 and 6.0 Part II

[http-equiv@excite.com]

Tuesday, February 25, 2003

We are delighted to learn that the original self-executing html file,
from June 1 2002 is now fixed with the most current of the many
patches for the Internet Explorer series of browsers. See:

http://online.securityfocus.com/archive/1/275126

Regrettably.

The following file is an html file comprising both scripting and an
executable [*.exe].

We inject scripting and an executable into the html file which is
designed to point back to the executable in the html file and execute
it. Provided the html file is an html file, Internet Explorer 5.5 and
6.0 will execute it.

Because it is an html file proper, Internet Explorer opens it. The
scripting inside is then parsed and fired. That scripting is pointing
back to the same executable file with our original codebase object
from the year 2000 and because it is a self-executing html file, it
executes !

Tested IE5.5 and IE6. Fully self-contained harmless *.exe:

Be aware of html files out there.

This does not seem to work for me if done via webserver. It works like a
charm locally, so it might be worthwile adding that this is only useful as
an attached HTML (in an email, for example).

..zip is the must importent issue.

the Zip is the key point in this Perfect demo by http-equiv .

you can do more cool things with Jscript like getting Windows User Name
(via document.location) or run even regular EXE (TIF Enumeration).

becouse the zip temp file run without Security Zone Check.
