CVE CVSS Summary
CVE-2018-1000115 7.3 (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) Memcached service on Juniper Networks Contrail Service Orchestration is accessible without authentication. This may allow network based attackers to read information stored in the memcached database or conduct distributed denial of service attacks (DDoS).

Note: It is recommended to install CSO in a trust zone behind a security firewall. For all these vulnerabilities to be exploited, an attacker first needs to gain access to the trust zone.
