The ARP table may also be updated through gratuitous announcements whenever a host announces its own MAC address without being asked for.This expected protocol behavior allows for a variety of malicious actions, such as Do S (Denial of Service), session hijacking and MITM (man-in-the-middle) attacks.But wait, we are talking about a threat as old as ARP specification from 1982.

Services like Shodan may have been used to identify vulnerable systems.Mitigation Most of the mitigations for ARP Spoofing attacks are made by network switches using DHCP Snooping and Dynamic ARP Inspection (DAI) techniques.The specific feature names may vary by switch brand, but basically, they allow only authorized ARP announcements to travel over the network.If we look at the CVE history, we can find several vulnerabilities relating to this feature: As you can see by the CVE numbers, there are reports for vulnerabilities since 2011 up to this year (2018).We can perhaps conjecture that more vulnerabilities might be discovered in the near future.
