## URL Fuzzing

### Fuzz Faster U Fool

* Simple Fuzzing
```sh
ffuf -u http://<IP>/FUZZ -w /usr/share/seclists/Discovery/Web-Content/big.txt
```

* Fuzz dirs
```sh
ffuf -u http://<IP>/FUZZ -w /usr/share/seclists/Discovery/Web-Content/raft-medium-directories-lowercase.txt
```

* Fuzz files
```sh
ffuf -u http://<IP>/FUZZ -w /usr/share/seclists/Discovery/Web-Content/raft-medium-words-lowercase.txt -e .php,.txt
```

* Fuzz all existing websites regardless of HTTP status
```sh
ffuf -c -w /usr/share/seclists/Discovery/Web-Content/common.txt -u http://$IP/FUZZ -fs 0 -mc all
```

* Fuzz with other HTTP methods like POST
```sh
ffuf -c -w /usr/share/seclists/Discovery/Web-Content/big.txt -u http://$IP/FUZZ -fs $SIZE -mc all -C POST
```

#### Fuzz parameters

```sh
ffuf -u 'http://MACHINE_IP/sqli-labs/Less-1/?FUZZ=1' -c -w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt -fw 39
ffuf -u 'http://MACHINE_IP/sqli-labs/Less-1/?FUZZ=1' -c -w /usr/share/seclists/Discovery/Web-Content/raft-medium-words-lowercase.txt -fw 39
```
* Fuzz values
```sh
seq 0 255 | fuff -u 'http://<IP>/sqli-labs/Less-1/?id=FUZZ -c -w - -fw 33
```
* Fuzz Post Methods
```sh
ffuf -u http://<IP>/sqli-labs/Less-11/ -c -w /usr/share/seclists/Passwords/Leaked-Databases/hak5.txt -X POST -d 'uname=Dummy&passwd=FUZZ&submit=Submit' -fs 1435 -H 'Content-Type: application/x-www-form-urlencoded'
```

#### Fuzz Users and use Bruteforce

* Fuzz users and write file
```sh
ffuf -w /usr/share/seclists/Usernames/Names/names.txt -X POST -d "username=FUZZ&email=x&password=x&cpassword=x" -H "Content-Type: application/x-www-form-urlencoded" -u http://<targetURL>/customers/signup -mr "username already exists" -o fuff.out
```
* Use users saved in `fuff.out` to bruteforce
```sh
ffuf -w userlist.txt:W1,/usr/share/seclists/Passwords/Common-Credentials/10-million-password-list-top-100.txt:W2 -X POST -d "username=W1&password=W2" -H "Content-Type: application/x-www-form-urlencoded" -u http://<targetURL>/customers/login -fc 200
```
#### Fuzz Subdomains

```sh
ffuf -u http://FUZZ.test.com -c -w  /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt
```
or if the subdomains are listed in the target's host file
```sh
ffuf -w /usr/share/seclists/Discovery/DNS/namelist.txt -H "Host: FUZZ.test.com" -u http://<target-IP> -fs 0
```
* Fuzz Vhosts & Server Blocks
```sh
ffuf -u http://FUZZ.test.com -c -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt -fs 0
ffuf -u http://test.com -c -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt -H 'Host: FUZZ.test.com' -fs 0
```

#### Proxy

* `-replay-proxy <IP>` or `-x <ProxyIP>`
