## PORT 139/445 (SMB)
Let's see if we can access any shares on the machine
<img src="https://imgur.com/tHZtw5N.png"/>
Seems like we can't so knowing this is a windows xp machine , it might be vulnerable to SMB exploit since this is a very old windows operating system , so let's run nmap `vuln` script to confirm the vulnerability.
```bash
nmap -p 445 --script vuln 10.10.10.4
Starting Nmap 7.80 ( https://nmap.org ) at 2021-05-13 01:02 PKT
Nmap scan report for 10.10.10.4
Host is up (0.19s latency).

This confirms that this machine is vulnerable to smb exploit so here I'll show case using with and without metasploit
## Metasploit
This CVE for this exploit is MS08-067

Configure the options in the exploit

## Without Metasploit

Here we can see that it's using a shell code of msfvenom reverse shell payload so we need to generate one
<img src="https://imgur.com/VWr1TNl.png"/>
Replace the shellcode which is in the script

Now let's run the script

Here it says it needs the target IP and port also the version of windows xp so I ran the aggressive scan to know which version of windows xp is this and chances were that it is XP 3

And we get a shell
