CVE-2019-12405 — Apache Traffic Control security vulnerability

Critical CVSS 9.8

Improper authentication is possible in Apache Traffic Control versions 3.0.0 and 3.0.1 if LDAP is enabled for login in the Traffic Ops API component. Given a username for a user that can be authenticated via LDAP, it is possible to improperly authenticate as that user without that user's correct password.

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.
