针对David Litchfield发现的MSSQL OpenDataSource函数漏洞的攻击程序源码
/*****************************************************************************/
/* THCsql 0.1 - MSSQL Server exploit for Server < SP3 */
/* Exploit by: Johnny Cyberpunk (jcyberpunk@thehackerschoice.com) */
/* THC PUBLIC SOURCE MATERIALS */
/* */
/* The exploit can be freely distributed ! */
/* */
/* This is just another exploit for the well known mssql server bug which */
/* was found by David Litchfield last summer. Details in this advisory: */
/* http://www.nextgenss.com/advisories/mssql-udp.txt */
/* */
/* This exploit was tested on an english Windows 2k Server SP2 and MSSQL */
/* Server with SP0 and SP2 and has worked properly. The used shellcode is */
/* completely offsetless, which makes this exploit quite stable */
/* */
/* After successful exploitation of this bug, a commandshell should spawn on */
/* TCP port 31337 ! Use netcat to connect to this port ! */
/* */
/* If there's no connectable port 31337, maybe it's blocked by a firewall ! */
/* */
/* compile with MS Visual C++ : cl THCsql.c /link ws2_32.lib */
/* */
/* At least some greetz fly to : THC, Halvar Flake, FX, gera, MaXX, dvorak, */
/* scut, stealth, zip, zilvio and the rest of the combo ...... */
