# SixOfDiamonds - 8200

At first, we can see an apache server running, so let's see what is serving.

It seems a site for uploading photos.

Let's upload a photo:

![images/3-3.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-3.png)

It's okay, and we can see it on
[http://127.0.0.1:8200/images/moose.jpg](http://127.0.0.1:8200/images/moose.jpg)

Let's try to upload a php file:

![images/3-4.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-4.png)

Not allowed php files. Let's change its name:

![images/3-5.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-5.png)

Mmm. Let's now to copy this php file below the head of the image, but first of all, we must to put our IP into it

And

![images/3-7.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-7.png)

Now it worked:

![images/3-8.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-8.png)

Now, opening a listener in our machine and opening the
[http://127.0.0.1:8200/images/moose.jpg.php](http://127.0.0.1:8200/images/moose.jpg.php) file should works

And here we are.

![images/3-9.png](https://raw.githubusercontent.com/NikNitro/CTFs/master/Writeups/2020-Metasploit/images/3-9.png)

And, doing a
```
find / -name "*.png" 2>/dev/null
```
we find our flag:
