Summary
The Quantenna Wi-Fi chips ship with an unauthenticated telnet interface by default. This is an instance of CWE-306, "Missing Authentication for Critical Function," and is estimated as a CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). This issue affects Quantenna Wi-Fi chipset through version 8.0.0.28 of the latest SDK, and appears to be unpatched at the time of this CVE record's first publishing, though the vendor has released a best practices guide for implementors of this chipset.
