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.
