Is port 5049 dangerous?

We have no specific security note for port 5049. Its risk depends on the program actually listening on it. General advice for web services:

  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 5049, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5049'      # process listening on 5049
sudo lsof -nP -i :5049

macOS

sudo lsof -nP -i :5049

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5049 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5049
netstat -ano | findstr :5049

From another machine

nmap -p 5049 -sV <host>
sudo nmap -sU -p 5049 <host>
nc -zv <host> 5049

Block it in the firewall

sudo ufw deny 5049/tcp                                         # Linux (ufw)
