CVE-2017-9132 — Mimosa Backhaul Radios security vulnerability

High CVSS 7.5

A hard-coded credentials issue was discovered on Mimosa Client Radios before 2.2.3, Mimosa Backhaul Radios before 2.2.3, and Mimosa Access Points before 2.2.3. These devices run Mosquitto, a lightweight message broker, to send information between devices. By using the vendor's hard-coded credentials to connect to the broker on any device (whether it be an AP, Client, or Backhaul model), an attacker can view all the messages being sent between the devices. If an attacker connects to an AP, the AP will leak information about any clients connected to it, including the serial numbers, which can be used to remotely factory reset the clients via a page in their web interface.

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.
