An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface of an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.\r\nNote: LLDP is a Layer 2 link protocol. To exploit this vulnerability, an attacker would need to be directly connected to an interface of an affected device, either physically or logically (for example, through a Layer 2 Tunnel configured to transport the LLDP protocol)."},{"lang":"es","value":"Una vulnerabilidad en la función del Protocolo de Descubrimiento de Capa de Enlace (LLDP) del software Cisco NX-OS podría permitir a un atacante adyacente no autenticado provocar el reinicio del proceso LLDP, lo que podría causar que un dispositivo afectado se recargue inesperadamente.\n\nEsta vulnerabilidad se debe al manejo inadecuado de campos específicos en una trama LLDP. Un atacante podría explotar esta vulnerabilidad enviando un paquete LLDP manipulado a una interfaz de un dispositivo afectado. Un exploit exitoso podría permitir al atacante provocar la recarga del dispositivo, lo que resultaría en una condición de denegación de servicio (DoS).\nNota: LLDP es un protocolo de enlace de Capa 2. Para explotar esta vulnerabilidad, un atacante necesitaría estar directamente conectado a una interfaz de un dispositivo afectado, ya sea física o lógicamente (por ejemplo, a través de un túnel de Capa 2 configurado para transportar el protocolo LLDP)."}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":7.4,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":4.0}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Primary","description":[{"lang":"en","value":"CWE-805"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-n3kn9k_aci_lldp_dos-NdgRrrA3","source":"psirt@cisco.com"}]}}]}
