CVE-2019-1684
Estado: ModificadaMedia (6.5)—
A vulnerability in the Cisco Discovery Protocol or Link Layer Discovery Protocol (LLDP) implementation for the Cisco IP Phone 7800 and 8800 Series could allow an unauthenticated, adjacent attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to missing length validation of certain Cisco Discovery Protocol or LLDP packet header fields. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol or LLDP packet to the targeted phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition. Versions prior to 12.6(1)MN80 are affected.

"value": "Una vulnerabilidad en la implementación de Cisco Discovery Protocol o en Link Layer Discovery Protocol (LLDP) en Cisco IP Phone 7800 and 8800 Series podría permitir que un atacante adyacente no autenticado provoque que un teléfono afectado se recargue inesperadamente, lo que resulta en una condición temporal de denegación de servicio (DoS). Esta vulnerabilidad se debe a la falta de una validación de longitud de determinados campos de cabeceras de paquetes Cisco Discovery Protocol o LLDP. Un atacante podría explotar esta vulnerabilidad enviando un paquete Cisco Discovery Protocol o LLDP malicioso al teléfono objetivo. Si se explota con éxito, podría permitir que el atacante consiga que el teléfono afectado se reinicie, provocando una denegación de servicio (DoS) temporal. Todas las versiones anteriores a la 12.6(1)MN80 se ven afectadas."
