Hi,
SCan report shows vulnerability as "mDNS Detection (Remote Network) ".
Can someone please let me know how to fix the vulnerability.
#cat /etc/redhat-release
CentOS Linux release 8.4.2105
mDNS Detection (Remote Network)
Re: mDNS Detection (Remote Network)
It means your TCP and/or UDP port 5353 is open and something is listening on that port. If it's not required then either close it or stop the process or both.
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: mDNS Detection (Remote Network)
Thank you.
Found online that the service related to mdns is "avahi-daemon".
Tried to stop the service
sudo systemctl stop avahi-daemon.socket avahi-daemon.service
Job for avahi-daemon.service canceled.
Job for avahi-daemon.socket canceled.
but check again the status and its running. Any idea how to stop the service or block the port 5353. Thank you
