CVE-2016-9207
A vulnerability in the HTTP traffic server component of Cisco Expressway could allow an unauthenticated, remote attacker to initiate TCP connections to arbitrary hosts.
Does this matter?
Lower severity and a low EPSS score (2.02%). Track it; it rarely justifies an emergency change on its own.
