CVE-2020-10137 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.70% chance of exploitation in the next 30 days.
