Windows Compressed Zip File Exploit Code (MS04-034)
------------------------------------------------------------------------
SUMMARY
As we reported in our previous article:
<http://www.securiteam.com/windowsntfocus/6U00E0UBFC.html> Vulnerability
in Compressed (zipped) Folders Allows Remote Code Execution (MS04-034), a
vulnerability in Windows' compressed folder support allows an attacker to
cause the Windows environment to execute arbitrary code by creating a
malformed zip file. The following exploit code can be used to test the
vulnerability on your system.
DETAILS
Exploit:
/* Microsoft Windows Vulnerability in Compressed (zipped) Folders
(MS04-034)
*
* Tested under Windows XP SP0 Spanish/English - SECU
*
* Original Advisory:
http://www.eeye.com/html/research/advisories/AD20041012A.html
* Exploit Date: 21/10/2004
*
* Tarako - Haxorcitos.com 2004

* THIS PROGRAM IS FOR EDUCATIONAL PURPOSES *ONLY* IT IS PROVIDED "AS IS"
* AND WITHOUT ANY WARRANTY. COPYING, PRINTING, DISTRIBUTION, MODIFICATION
* WITHOUT PERMISSION OF THE AUTHOR IS STRICTLY PROHIBITED.
*
* Greetings to: #haxorcitos, #dsr and #localhost @efnet
*
*
* How to get new offsets:
* 1) attach debugger (i.e ollydbg) to explorer.exe
* 2) open the zip file as a folder and add or move some files to it
* 3) search in the explorer.exe memory the shellcode and get the
addresses
