"According to its self-reported version number, the Cisco MSE version
installed on the remote host is prior to 8.0.120.7. It is, therefore,
affected by multiple vulnerabilities :

  - A local privilege escalation vulnerability exists due to
    the program using insecure permissions for binary files
    during its physical or virtual appliance installation
    procedure. A local attacker can exploit this, by writing
    to a file, to gain root privileges. (CVE-2015-4282)

  - A security bypass vulnerability exists due to the
    default configuration of sshd_config allowing logins by
    the 'oracle' account which has a hard-coded password. An
    unauthenticated, remote user can exploit this gain 
    privileged access to the system. (CVE-2015-6316)");
