* Microsoft Excel Remote Code Execution Proof Of Concept.
* Tested against : Excel 2000 on Win XP SP1 , and Win2000 SP4
* Description:
* Microsoft Excel is prone to a remote code execution issue
* which may be triggered when a malformed Excel document is opened.
* The issue is due to an error in Excel while handling malformed URL
* strings. there may be other ways to trigger this vulnerability,
* successful exploitation could allow an attacker to execute
* arbitrary code with the privileges of the user running Excel.
*
* Code execution is dependent upon certain factors including the
* overflow condition, the MS Excel version and the host OS and SP.
* If you cannot get it to work, attach it with the debugger check
* the stack layout and the rest is on your imagination. :) :)
*
* Compile with MS VC++ or g++ ,it will generate the Excel file
* Clicking the link in the file binds the shell ,
* C:\nc localhost 4444
