# Basic Information
|
|
|
|
**Trivial File Transfer Protocol (TFTP)** is a straightforward protocol used on **UDP port 69** that allows file transfers without needing authentication. Highlighted in **RFC 1350**, its simplicity means it lacks key security features, leading to limited use on the public Internet. However, **TFTP** is extensively utilized within large internal networks for distributing **configuration files** and **ROM images** to devices such as **VoIP handsets**, thanks to its efficiency in these specific scenarios.
|
|
|
|
**TODO**: Provide information about what is a Bittorrent-tracker (Shodan identifies this port with that name). If you have more info about this let us know for example in the [**HackTricks telegram group**](https://t.me/peass) (or in a github issue in [PEASS](https://github.com/carlospolop/privilege-escalation-awesome-scripts-suite)).
|
|
|
|
**Default Port:** 69/UDP
|
|
|
|
```
|
|
PORT STATE SERVICE REASON
|
|
69/udp open tftp script-set
|
|
```
|
|
|
|
# Enumeration
|
|
|
|
TFTP doesn't provide directory listing so the script `tftp-enum` from `nmap` will try to brute-force default paths.
|
|
|
|
```bash
|
|
nmap -n -Pn -sU -p69 -sV --script tftp-enum <IP>
|
|
```
|
|
|
|
## Download/Upload
|
|
|
|
You can use Metasploit or Python to check if you can download/upload files:
|
|
|
|
```bash
|
|
msf5> auxiliary/admin/tftp/tftp_transfer_util
|
|
```
|
|
|
|
```bash
|
|
import tftpy
|
|
client = tftpy.TftpClient(<ip>, <port>)
|
|
client.download("filename in server", "/tmp/filename", timeout=5)
|
|
client.upload("filename to upload", "/local/path/file", timeout=5)
|
|
```
|
|
|
|
## Shodan
|
|
|
|
* `port:69`
