These vulnerabilities are due to incorrect processing of certain Cisco Discovery Protocol and LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted Cisco Discovery Protocol or LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition. Note: Cisco Discovery Protocol and LLDP are Layer 2 protocols. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent)."},{"lang":"es","value":"Múltiples vulnerabilidades en la implementación de Cisco Discovery Protocol y Link Layer Discovery Protocol (LLDP) para Cámaras IP Cisco Video Surveillance 7000 Series, podrían permitir a un atacante adyacente no autenticado causar una pérdida de memoria, lo que podría conllevar a una condición de denegación de servicio (DoS) en un dispositivo afectado. Estas vulnerabilidades son debido al procesamiento incorrecto de determinados paquetes LLDP de Cisco Discovery Protocol en el momento de la entrada. Un atacante podría explotar estas vulnerabilidades mediante el envío de paquetes de Cisco Discovery Protocol o LLDP diseñados en un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar que el dispositivo afectado consuma continuamente memoria, lo que podría provocar que el dispositivo se bloquee y se recargue, resultando en una condición de DoS. Nota: Cisco Discovery Protocol y LLDP son protocolos de capa 2. Para explotar estas vulnerabilidades, un atacante debe estar en el mismo dominio de difusión que el dispositivo afectado (adyacente a la capa 2)"}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6},{"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:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:A/AC:L/Au:N/C:N/I:N/A:C","baseScore":6.1,"accessVector":"ADJACENT_NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"COMPLETE"},"baseSeverity":"MEDIUM","exploitabilityScore":6.5,"impactScore":6.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-401"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:video_surveillance_7530pd_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"2.12.3","matchCriteriaId":"3DA9D97B-13BD-4F9E-AA23-7F39F2133378"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:video_surveillance_7530pd:-:*:*:*:*:*:*:*","matchCriteriaId":"6DA18561-CB31-447C-8CFF-712DD1A13134"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:video_surveillance_7070_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"2.12.3","matchCriteriaId":"213FD4E3-83E2-477F-8008-6A6D4225C7FB"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:video_surveillance_7070:-:*:*:*:*:*:*:*","matchCriteriaId":"904D94DB-5EDF-42D0-BDEA-D19D221F9ADF"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipcamera-lldpcdp-mem-yTQDmjRO","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipcamera-lldpcdp-mem-yTQDmjRO","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
