Official Description

A vulnerability in Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, remote attacker to log in to an affected system by using an administrative account that has default, static user credentials. The vulnerability is due to the presence of undocumented, static user credentials for the default administrative account for the affected software. An attacker could exploit this vulnerability by using the account to log in to an affected system.

Technical Analysis

CVE-2018-0222 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.
