Descriptions

A vulnerability in the Precision Time Protocol (PTP) subsystem of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of the Precision Time Protocol. The vulnerability is due to insufficient processing of PTP packets. An attacker could exploit this vulnerability by sending a custom PTP packet to, or through, an affected device. A successful exploit could allow the attacker to cause a DoS condition for the PTP subsystem, resulting in time synchronization issues across the network.

Una vulnerabilidad en el subsistema Precision Time Protocol (PTP) de Cisco NX-OS Software podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en el protocolo PTP. Esta vulnerabilidad se debe al procesamiento insuficiente de paquetes PTP. Un atacante podría explotar esta vulnerabilidad enviando un paquete PTP personalizado a o a través de un dispositivo afectado. Su explotación con éxito podría permitir que el atacante provoque una condición de denegación de servicio (DoS) en el subsistema PTP, lo que resulta en problemas de sincronización temporal en la red.
