## PORT 139/445 (SMB)

Let's see if we can access any shares on the machine

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

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

## Without Metasploit

Download the POC for MS 08-067

Here we can see that it's using a shell code of msfvenom reverse shell payload so we need to generate one

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
