CVE-2012-4985
The Forescout CounterACT NAC device 6.3.4.1 does not block ARP and ICMP traffic from unrecognized clients, which allows remote attackers to conduct ARP poisoning attacks via crafted packets.
Does this matter?
Lower severity and a low EPSS score (1.72%). Track it; it rarely justifies an emergency change on its own.
