Can anyone describe this alert please?

enter image description here

I am confused if an attack is run against my network or not.

I run snort IDS/IPS through a pfsense firewall.

  • Can you provide more information? Like the payload of the packet? – bashCypher Jan 15 at 0:44

It is most probably a false positive like mentioned here https://community.spiceworks.com/topic/1514894-snort-attempted-command-buffer-overflow-smtp

you should provide more details such as is the traffic originating interally or any other logs you have.

  • How i can find more details , i just monitor the WAN interface – YOU CHT LEE Jan 14 at 17:23
