CVSS v3.1

Official Description

A vulnerability in the container management subsystem of Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, remote attacker to bypass authentication and gain elevated privileges. This vulnerability is due to an insecure default configuration of the Kubernetes container management subsystem within DNA Center. An attacker who has the ability to access the Kubernetes service port could execute commands with elevated privileges within provisioned containers. A successful exploit could result in a complete compromise of affected containers. This vulnerability affects Cisco DNA Center Software Releases 1.1.3 and prior. Cisco Bug IDs: CSCvi47253.

Technical Analysis

CVE-2018-0268 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
