  意思是让我们更努力的去爆破目录？
  
• python .\dirsearch.py -u http://192.168.75.137/ --suffixes .txt,.zip 给字典加上.txt,.zip 后缀去爆破

  7. Happy hacking.

  让我们进行fuzz爆破，大概意思是让我们在所有php文件进行fuzz ，大概就是让我们fuzz出get参数
  
• 扫描出所有php文件
  1. http://192.168.75.137/secret.txt

  复制代码
  当前目录下只有两个php文件我们两个都试试
  
• 对index.php进行fuzz
  注意 --hh 136 需要对视情况进行调整，过滤掉其他结果后，最后得出file这个参数
  1. Looks like you have got some secrets.
  3. Ok I just want to do some help to you.
  5. Do some more fuzz on every page of php which was finded by you. And if
  6. you get any right parameter then follow the below steps. If you still stuck
  7. Learn from here a basic tool with good usage for OSCP.

  大概file的参数也需要我们进行fuzz，实在这事burp也可以做
  但是之前的secret.txt还有一句 : //see the location.txt and you will get your next move//
  以是我们访问 ：http://192.168.75.137/index.php?file=location.txt
  果然存在有信息
  1. wfuzz -c -w /usr/share/wfuzz/wordlist/general/common.txt --hh 136 http://192.168.75.137/index.php?FUZZ=something

  让我们使用secrettier360 参数去别的php页面fuzz ，大概是
  别的php页面除了index.php那就是image.php
  
• 对image.php 进行fuzz
  1. 提示：Do something better you are digging wrong file

  复制代码
  得出参数dev ，实验访问：http://192.168.75.137/image.php?secrettier360=dev
  1. Now dig some more for next one
  2. use 'secrettier360' parameter on some other php page for more fun.

  复制代码
  WTF？这不是之前的/dev吗，但是发现你只要在secrettier360 加上文件名，那不就是文件包罗了吗?我这里大发奇想使用php伪协议实验，但是发现使用不了，应该是禁用了
  
• 利用文件包罗漏洞
  实验读取/etc/passwd
  1. wfuzz -c -w /usr/share/wfuzz/wordlist/general/common.txt --hh 197 http://192.168.75.137/image.php?secrettier360=FUZZ

  发现saket:x:1001:1001:find password.txt file in my directory:/home/saket: ，好好好
  1. finaly you got the right parameter
  3. hello, now you are at level 0 stage. In real life pentesting we should use our tools to dig on a web very hard. Happy hacking.

  复制代码
  密码应该是follow_the_ippsec
  
• 登录wordpress背景，用户名victor，密码follow_the_ippsec
  为什么用户名是victor ，由于wordpress/index.php里面第一条信息就是victor 发布的，以是猜测用户名是victor ，成功进入背景
  

背景利用获得低级shell

<ol>进入背景，plugins → Add New → upload plugins ,上传反弹shell文件

发现没有上传权限，纵然设置关闭了以月份创建文件夹
探求别的地方上传shellcode
在Appearance→Theme Editor →secret.php 找到了可编辑保存的文件
我们将shellcode输进去
[code]
