Is port 5022 dangerous?

We have no specific security note for port 5022. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 5022, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5022'      # process listening on 5022
sudo lsof -nP -i :5022

macOS

sudo lsof -nP -i :5022

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5022 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5022
netstat -ano | findstr :5022

From another machine

nmap -p 5022 -sV <host>
sudo nmap -sU -p 5022 <host>
nc -zv <host> 5022

Block it in the firewall

sudo ufw deny 5022/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5022" -Direction Inbound -LocalPort 5022 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5022 used for?

Port 5022 is assigned by IANA to mice (mice server).

Is port 5022 TCP or UDP?

Port 5022 is registered for TCP and UDP.

Is it safe to open port 5022?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 5022 is open?

On Linux run "ss -ltnup 'sport = :5022'", on macOS "lsof -nP -i :5022", and on Windows "netstat -ano | findstr :5022" to see the local process. From another machine, "nmap -p 5022 <host>" shows whether it is reachable.
