The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent)."},{"lang":"es","value":"Una vulnerabilidad en la implementación de Cisco Discovery Protocol para Cisco IP Phone, podría permitir a un atacante adyacente no autenticado ejecutar código remotamente con privilegios root o causar una recarga de un teléfono IP afectado. La vulnerabilidad es debido a una falta de comprobaciones cuando se procesan los mensajes de Cisco Discovery Protocol. Un atacante podría explotar esta vulnerabilidad mediante el envío de un paquete de Cisco Discovery Protocol diseñado hacia el teléfono IP apuntado. Una explotación con éxito podría permitir al atacante ejecutar código remotamente con privilegios root o provocar una recarga de un teléfono IP afectado, resultando en una condición de denegación de servicio (DoS). Cisco Discovery Protocol es un protocolo de Capa 2. Para explotar esta vulnerabilidad, un atacante debe encontrarse en el mismo dominio de difusión que el dispositivo afectado (Capa 2 adyacente)."}],"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","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"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","baseScore":8.3,"accessVector":"ADJACENT_NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"COMPLETE","integrityImpact":"COMPLETE","availabilityImpact":"COMPLETE"},"baseSeverity":"HIGH","exploitabilityScore":6.5,"impactScore":10.0,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-20"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_conference_phone_7832_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"12.7\\(1\\)","matchCriteriaId":"2C412D40-7E0A-4FF1-9D07-21117B915509"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_conference_phone_7832_with_multiplatform_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"4A2F31BA-AF80-4C21-9FD0-A0DB1D304024"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_conference_phone_7832:-:*:*:*:*:*:*:*","matchCriteriaId":"6592E7FE-346E-4923-97C2-F5298DC802A3"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_conference_phone_8832_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"12.7\\(1\\)","matchCriteriaId":"6158B805-6515-4DC3-AB76-1D2F7036492F"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_conference_phone_8832_with_multiplatform_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"F8096985-5813-4098-BF38-FD09CB2ACBFA"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_conference_phone_8832:-:*:*:*:*:*:*:*","matchCriteriaId":"F1010D16-DC6E-47A6-8BF9-C1026D975E3D"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_phone_6821_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"327BB99F-F398-49C3-83A2-DE8392F13A51"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_phone_6821:-:*:*:*:*:*:*:*","matchCriteriaId":"AEFD67F1-8FB1-4F27-8B97-59DF78DE41A1"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_phone_6841_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"1021FD6B-50A7-40E1-8081-F7BD80777E75"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_phone_6841:-:*:*:*:*:*:*:*","matchCriteriaId":"CE4960B1-22B4-4B3D-955E-684DA520A1A5"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_phone_6851_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"4CEB6D52-F968-4D81-A0E0-F9E81CCBF1AF"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_phone_6851:-:*:*:*:*:*:*:*","matchCriteriaId":"5809CA01-CF32-4E3A-A771-01D5065F0061"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_phone_6861_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","matchCriteriaId":"E38A06CF-5C29-47EA-8E63-45DED1085864"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:ip_phone_6861:-:*:*:*:*:*:*:*","matchCriteriaId":"C05A7CA6-AD58-45D7-AF32-129E22855D8E"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ip_phone_6871_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"11.3\\(1\\)sr1","mat
