\r
3 /* Exploit by: Johnny Cyberpunk (jcyberpunk@thehackerschoice.com) */
\r
4 /* THC PUBLIC SOURCE MATERIALS */
\r
6 /* The exploit can be freely distributed ! */
\r
8 /* This is the much more reliable version of the Realserver < 8.0.2 exploit */
\r
9 /* Tested with different OSes and Realserver Versions */
\r
11 /* While probing lot's of boxes via 'OPTIONS / RTSP/1.0' on TCP port 554 */
\r
12 /* i noticed that 99% of the probed machines are not up2date yet ! =;O) */
\r
14 /* The shellcode is much shorter than the one in version 0.1 now and of */
\r
15 /* course offsetless ! The encoder in front of the exploit is needed coz the */
\r
16 /* shellcode has next to 0x00,0x0d,0x0a also to be 0x20 and 0xff free ! */
\r
18 /* After successful exploitation of this bug, a commandshell should spawn on */
\r
19 /* TCP port 31337 ! Use netcat to connect to this port ! */
\r
21 /* If there's no connectable port 31337, maybe it's blocked by a firewall ! */
\r
23 /* Unfortunately i hadn't a Linux/Sparc or whatever Platform Realserver 8 */
\r
24 /* runs on. I just know it's also exploitable on other OSs ! */
\r
25 /* So if u wanna exploit other platforms, try to get Realserver 8 and use */
\r
26 /* gdb to find out, how this can be exploited ! Good luck ! */
\r
28 /* compile with MS Visual C++ : cl THCunREAL.c /link ws2_32.lib */
\r
30 /* At least some greetz fly to : THC, Halvar Flake, FX, gera, MaXX, dvorak, */
\r
31 /* scut, stealth, zip, zilvio and the rest of the combo ...... */
