An attacker can also capture and replay Z-Wave traffic. Firmware upgrades cannot directly address this vulnerability as it is an issue with the Z-Wave specification for these legacy chipsets. One way to protect against this vulnerability is to use 500 or 700 series chipsets that support Security 2 (S2) encryption. As examples, the Linear WADWAZ-1 version 3.43 and WAPIRZ-1 version 3.43 (with 300 series chipsets) are vulnerable." }, { "lang": "es", "value": "Los dispositivos Z-Wave basados en los conjuntos de chips de las series 100, 200 y 300 de Silicon Labs no admiten cifrado, permitiendo a un atacante dentro del alcance de la radio tomar el control o causar una denegaci\u00f3n de servicio en un dispositivo vulnerable. Un atacante tambi\u00e9n puede capturar y reproducir el tr\u00e1fico Z-Wave. Las actualizaciones de firmware no pueden abordar directamente esta vulnerabilidad, ya que es un problema con la especificaci\u00f3n Z-Wave para estos conjuntos de chips heredados. Una forma de protegerse contra esta vulnerabilidad es usar los conjuntos de chips de las series 500 o 700 que soportan el cifrado de Seguridad 2 (S2). Como ejemplos, el Linear WADWAZ-1 versi\u00f3n 3.43 y WAPIRZ-1 versi\u00f3n 3.43 (con chipsets de la serie 300) son vulnerables" } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "attackVector": "ADJACENT_NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 2.8, "impactScore": 5.9 } ], "cvssMetricV2": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "2.0", "vectorString": "AV:A/AC:L/Au:N/C:C/I:C/A:C", "accessVector": "ADJACENT_NETWORK", "accessComplexity": "LOW", "authentication": "NONE", "confidentialityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "baseScore": 8.3 }, "baseSeverity": "HIGH", "exploitabilityScore": 6.5, "impactScore": 10.0, "acInsufInfo": false, "obtainAllPrivilege": false, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-311" } ] }, { "source": "cret@cert.org", "type": "Secondary", "description": [ { "lang": "en", "value": "CWE-311" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linear:wadwaz-1:3.43:*:*:*:*:*:*:*", "matchCriteriaId": "29A637D2-2EEB-46FA-925E-230467C662FB" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linear:wapirz-1:3.43:*:*:*:*:*:*:*", "matchCriteriaId": "62E39D10-8B14-4377-A7A6-CE75DFC6B349" } ] } ] }, { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:silabs:100_series_firmware:*:*:*:*:*:*:*:*", "matchCriteriaId": "FD65067D-33BE-47A3-8586-9B7165D44120" }, { "vulnerable": true, "criteria": "cpe:2.3:o:silabs:200_series_firmware:*:*:*:*:*:*:*:*", "matchCriteriaId": "5E0D4883-9F5A-447F-85ED-E47D0C5A4940" }, { "vulnerable": true, "criteria": "cpe:2.3:o:silabs:300_series_firmware:*:*:*:*:*:*:*:*", "matchCriteriaId": "357345BC-2448-46B7-8DED-13B291708DF0" } ] } ] } ], "references": [ { "url": "https://doi.org/10.1109/ACCESS.2021.3138768", "source": "cret@cert.org", "tags": [ "Broken Link" ] }, { "url": "https://github.com/CNK2100/VFuzz-public", "source": "cret@cert.org", "tags": [ "Third Party Advisory" ] }, { "url": "https://ieeexplore.ieee.org/document/9663293", "source": "cret@cert.org", "tags": [ "Broken Link" ] }, { "url": "https://kb.cert.org/vuls/id/142629", "source": "cret@cert.org", "tags": [ "Third Party Advisory", "US Government Resource" ] }, { "url": "https://www.kb.cert.org/vuls/id/142629", "source": "cret@cert.org", "tags": [ "Third Party Advisory", "US Government Resource" ] } ] }
