Is port 4305 dangerous?

We have no specific security note for port 4305. 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.

sudo ss -ltnup 'sport = :4305'      # process listening on 4305
sudo lsof -nP -i :4305

macOS

sudo lsof -nP -i :4305

Get-NetTCPConnection -LocalPort 4305 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4305
netstat -ano | findstr :4305

From another machine

nmap -p 4305 -sV <host>
sudo nmap -sU -p 4305 <host>
nc -zv <host> 4305

Block it in the firewall
