oc192-dcom.c: Posted Aug 6, 2003; Authored by sw | Site oc192.us; RPC DCOM remote Windows exploit. Includes 2 universal targets, 1 for win2k, and 1 for winXP. This exploit uses ExitThread in its shellcode to prevent the RPC service from crashing upon successful exploitation. It also has several other options including definable bindshell and attack ports.; tags | exploit, remote, shellcode; systems | windows; SHA-256 | 51e52375501a20b7887981d8cad4867174ea62a3ed29f29ee6a2c3b1d52c5c71; Download | Favorite | View

/* Windows 2003 <= remote RPC DCOM exploit
 * Coded by .:[oc192.us]:. Security
 *
 * Features:
 *
 * -d destination host to attack.
 *
 * -p for port selection as exploit works on ports other than 135(139,445,539 etc)
 *
 * -r for using a custom return address.
 *
 * -t to select target type (Offset) , this includes universal offsets for - 
 *    win2k and winXP (Regardless of service pack)
 *
 * -l to select bindshell port on remote machine (Default: 666)
 *
 * - Shellcode has been modified to call ExitThread, rather than ExitProcess, thus 
 *   preventing crash of RPC service on remote machine.
 * 
 *   This is provided as proof-of-concept code only for educational 
 *   purposes and testing by authorized individuals with permission to 
 *   do so.
