CVE-2018-0222 affects all versions of Cisco Digital Network Architecture Center prior to version 1.1.3. Static default credentials in the software may allow a threat actor to log into a system and execute commands with root privileges.

CVE-2018-0268 affects all versions of Cisco Digital Network Architecture Center prior to version 1.1.4. A threat actor that has the ability to access the Kubernetes service port may execute commands with escalated privilege and compromise all affected containers.

CVE-2018-0271 affects versions prior to 1.1.2 of Cisco Digital Network Architecture Center.
