CVE-2019-13559 — GE Mark VIe Controller is shipped with pre-configured hard-coded credentials that may allow root-user access to the controller

High CVSS 7.8

GE Mark VIe Controller is shipped with pre-configured hard-coded credentials that may allow root-user access to the controller. A limited application of the affected product may ship without setup and configuration instructions immediately available to the end user. The bulk of controllers go into applications requiring the GE commissioning engineer to change default configurations during the installation process. GE recommends that users reset controller passwords during installation in the operating environment.

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.
