CVE-2018-19023 — Hetronic Nova-M prior to verson r161 uses fixed codes that are reproducible by sniffing and re-transmission

High CVSS 8.8

Hetronic Nova-M prior to verson r161 uses fixed codes that are reproducible by sniffing and re-transmission. This can lead to unauthorized replay of a command, spoofing of an arbitrary message, or keeping the controlled load in a permanent "stop" state.

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.
