CVE-2023-22597Network attack vector

MQTT command injection via cleartext cloud credentials

Published Jan 12, 2023 · Updated Jan 16, 2025

Cleartext transmission in InHand Networks InRouter 302 and 615 firmware allows remote attackers to intercept cloud communications. The routers use an unsecured channel by default, exposing configuration data and MQTT credentials in transit. A network-positioned attacker can use the intercepted credentials to inject MQTT commands into cloud-managed devices.
