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.
