HTB靶场系列 Windows靶机 Slio靶机

这台机器涉及到了oracle数据库，之前完全没有涉猎过，借此机会也是熟悉了一下这个数据库的操作方法；以及涉及到了关于内存取证方面的知识，正好上一次在美亚杯只是粗浅的学习了一下取证大师，则此也是借此机会好好的学习了一下取证相关知识

勘探

可以看出来80端口开了iis8.5，搜索一下没有可以利用的漏洞，应该是个兔子洞

135,和五位数都是rpc没有可以利用漏洞

rpcclient -U '' 10.10.10.82
Enter WORKGROUP\'s password: 
Cannot connect to server.  Error was NT_STATUS_LOGON_FAILURE

139和445可以看出对方系统的，并且共享文件夹中也没有东西

$smbclient -L //$ip/
Enter WORKGROUP\chris's password: 
session setup failed: NT_STATUS_ACCESS_DENIED
┌─[root@kali]─[~]
└──╼ $smbmap -H $ip
[!] 445 not open on 10.10.10.82....

1521是oracle-tns Oracle TNS listener这个是一个Oracle数据库的监听端口，有一个可以利用的漏洞

获取system权限

方法一

这种方法不需要获取www权限

首先安装odat，直接在kali中打odat然后就会自动开始安装

然后开始利用
