FKIE_CVE-2020-10137

Vulnerability from fkie_nvd - Published: 2022-01-10 14:10 - Updated: 2026-06-17 02:47
Severity
6.5 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Z-Wave devices based on Silicon Labs 700 series chipsets using S2 do not adequately authenticate or encrypt FIND_NODE_IN_RANGE frames, allowing a remote, unauthenticated attacker to inject a FIND_NODE_IN_RANGE frame with an invalid random payload, denying service by blocking the processing of upcoming events.
