The Naxclow platform API that returns device relay registration details exposes a persistent credential without verifying that the requester is the legitimate device or owner. An actor able to present a platform-valid request signature can retrieve credentials for arbitrary devices and register on the relay as that device, enabling interception and disruption of its communications.
Naxclow did not respond to CISA's attempts to coordinate these vulnerabilities. Users should contact Naxclow for more information.
