CVE-2019-11523 — Anviz Global M3 Outdoor RFID Access Control executes any command received from any source

Critical CVSS 9.8

Anviz Global M3 Outdoor RFID Access Control executes any command received from any source. No authentication/encryption is done. Attackers can fully interact with the device: for example, send the "open door" command, download the users list (which includes RFID codes and passcodes in cleartext), or update/create users. The same attack can be executed on a local network and over the internet (if the device is exposed on a public IP address).

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.
