CVE-2017-16241 — Amag En-1Dbc Firmware security vulnerability

High CVSS 7.5

Incorrect access control in AMAG Symmetry Door Edge Network Controllers (EN-1DBC Boot App 23611 03.60 and STD App 23603 03.60; EN-2DBC Boot App 24451 01.00 and STD App 2461 01.00) enables remote attackers to execute door controller commands (e.g., lock, unlock, add ID card value) by sending unauthenticated requests to the affected devices via Serial over TCP/IP, as demonstrated by a Ud command.

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.
