CVE-2023-22601Network attack vector

Device information disclosure via predictable MQTT ClientIDs

Published Jan 12, 2023 · Updated Jan 16, 2025

Insufficient randomness in InHand Networks InRouter 302 and 615 firmware allows remote attackers to discover cloud-managed devices. The firmware fails to randomize MQTT ClientID parameters, making the identifiers calculable and usable to gather device information. Exploitation requires access to the shared cloud-management context and discloses information about other managed devices without altering them.
