Forescout NAC ICMP and ARP Protocols Not Filtered Vulnerability Advisory 
(CVE-2012-4985)

Forescout NAC (Network Access Control) device is vulnerable to ICMP and ARP 
protocol filter bypass. The NAC does not filter traffic from unknown clients 
over these protocols. An attacker with an unauthorised device can engage ARP 
poisoning attacks and potentially gain access to cleartext login credentials 
traversing the network (where cleartext protocols are employed). The attacker 
could then use these credentials via an authorised terminal/workstation to gain 
full access to the network.
