Is port 1248 dangerous?

We have no specific security note for port 1248. 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 1248, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1248'      # process listening on 1248
sudo lsof -nP -i :1248

macOS

sudo lsof -nP -i :1248

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1248 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1248
netstat -ano | findstr :1248

From another machine

nmap -p 1248 -sV <host>
sudo nmap -sU -p 1248 <host>
nc -zv <host> 1248

Block it in the firewall

sudo ufw deny 1248/tcp                                         # Linux (ufw)

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 1248 is open?

On Linux run "ss -ltnup 'sport = :1248'", on macOS "lsof -nP -i :1248", and on Windows "netstat -ano | findstr :1248" to see the local process. From another machine, "nmap -p 1248 <host>" shows whether it is reachable.
