According to its self-reported version number, the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) application running on the remote host is 1.x prior to 1.5. It is, therefore, affected by a vulnerability within the firewall configuration of the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) that could allow an unauthenticated, adjacent attacker to gain privileged access to services only available on the internal network of the device.
