CVE-2021-33221Public exploitNetwork attack vector

Information disclosure and factory reset via unauthenticated APIs

Published Jul 7, 2021 · Updated Aug 3, 2024

Missing authentication in CommScope Ruckus IoT Controller 1.7.1.0 and earlier allows remote attackers to disclose data or factory-reset it. The service-details and diagnostic endpoints expose configuration data and generate support archives without a session, while POST /reset erases the appliance configuration without checking authorization. Network access to the controller API is sufficient; exposed data can include API keys and tokens, diagnostic generation consumes CPU and disk, and reset removes the current configuration.
