CVE-2018-0222 — Cisco Digital Network Architecture Center security vulnerability

Critical CVSS 10

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.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
