Descriptions

A vulnerability in system resource management in Cisco UCS 6400 and 6500 Series Fabric Interconnects that are in Intersight Managed Mode (IMM) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the Device Console UI of an affected device. This vulnerability is due to insufficient rate-limiting of TCP connections to an affected device. An attacker could exploit this vulnerability by sending a high number of TCP packets to the Device Console UI. A successful exploit could allow an attacker to cause the Device Console UI process to crash, resulting in a DoS condition. A manual reload of the fabric interconnect is needed to restore complete functionality.

Una vulnerabilidad en la administración de recursos del sistema en las interconexiones de estructura de las series Cisco UCS 6400 y 6500 que están en el modo administrado Intersight (IMM) podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en la interfaz de usuario de la consola del dispositivo de un dispositivo afectado. . Esta vulnerabilidad se debe a una limitación de velocidad insuficiente de las conexiones TCP a un dispositivo afectado. Un atacante podría aprovechar esta vulnerabilidad enviando una gran cantidad de paquetes TCP a la interfaz de usuario de la consola del dispositivo. Un exploit exitoso podría permitir que un atacante cause que el proceso de la interfaz de usuario de la consola del dispositivo se bloquee, lo que resultaría en una condición DoS. Es necesaria una recarga manual de la interconexión de fabric para restaurar la funcionalidad completa.
