CVE-2020-10137

TITLE

Silicon Labs Z-Wave chipsets contain multiple vulnerabilities

Trust: 0.8

sources: CERT/CC: VU#142629

DESCRIPTION

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. Various Silicon Labs Z-Wave chipsets do not support encryption, can be downgraded to not use weaker encryption, and are vulnerable to denial of service. Some of these vulnerabilities are inherent in Z-Wave protocol specifications.CVE-2020-10137 Unknown CVE-2020-9057 Affected Vendor Statement: This is a known weakness with unencrypted traffic. S0 and S2 security can encrypt application data. CVE-2020-9058 Affected Vendor Statement: This is a known weakness with unencrypted traffic. S0 and S2 can encrypt application data. CVE-2020-9059 Affected Vendor Statement: This is a known weakness with S0 security. CVE-2020-9060 Affected Vendor Statement: This is a known weakness with S2 security. CVE-2020-9061 Affected Vendor Statement: This is a known weakness with S0 and S2 security.CVE-2020-10137 Unknown CVE-2020-9057 Affected Vendor Statement: This is a known weakness with unencrypted traffic. S0 and S2 security can encrypt application data. CVE-2020-9058 Affected Vendor Statement: This is a known weakness with unencrypted traffic. S0 and S2 can encrypt application data. CVE-2020-9059 Affected Vendor Statement: This is a known weakness with S0 security. CVE-2020-9060 Affected Vendor Statement: This is a known weakness with S2 security. CVE-2020-9061 Affected Vendor Statement: This is a known weakness with S0 and S2 security. Silicon Labs 700 Series contains an insufficient validation of data authenticity vulnerability.Service operation interruption (DoS) It may be in a state
