CVE-2018-0278
CWE-200
Summary
o A vulnerability in the management console of Cisco Firepower System
Software could allow an unauthenticated, remote attacker to access
sensitive data about the system.
The vulnerability is due to improper cross-origin domain protections for
the WebSocket protocol. An attacker could exploit this vulnerability by
convincing a user to visit a malicious website designed to send requests to
the affected application while the user is logged into the application with
an active session cookie. A successful exploit could allow the attacker to
retrieve policy or configuration information from the affected software and
to perform another attack against the management console.
There are no workarounds that address this vulnerability.

CVE-2018-0283
CWE-310
Summary
A vulnerability in the detection engine of Cisco Firepower System Software
could allow an unauthenticated, remote attacker to restart an instance of
the Snort detection engine on an affected device, resulting in a brief
denial of service (DoS) condition.
The vulnerability is due to the incorrect handling of Transport Layer
Security (TLS) TCP connection setup for the affected software. An attacker
could exploit this vulnerability by sending crafted TLS traffic to an
affected device. A successful exploit could allow the attacker to cause the
Snort detection engine on the affected device to restart, resulting in a
DoS condition.
There are no workarounds that address this vulnerability.
