Descriptions

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. Nexus 3000 Series Switches are affected running software versions prior to 7.0(3)I4(9) and 7.0(3)I7(4). Nexus 3500 Platform Switches are affected running software versions prior to 7.0(3)I7(4). Nexus 3600 Platform Switches are affected running software versions prior to 7.0(3)F3(5). Nexus 9000 Series Switches in Stand are affected running software versions prior to 7.0(3)F3(5).

Una vulnerabilidad en la CLI del software NX-OS de Cisco podría permitir a un atacante local autenticado ejecutar comandos arbitrarios en el sistema operativo subyacente de un dispositivo afectado. La vulnerabilidad se debe a una validación de argumentos insuficiente que se envían a determinados comandos CLI. Un atacante podría explotar esta vulnerabilidad incluyendo entradas maliciosas como el argumento de un comando afectado. Un exploit con éxito podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente con privilegios elevados. Un atacante necesitaría credenciales de administrador válidas para explotar esta vulnerabilidad. Los switches de Nexus 3000 Series se ven afectados en versiones de software anteriores a las 7.0(3)I4(9) y 7.0(3)I7(4). Los switches de Nexus 3500 Platform se ven afectados en versiones de software anteriores a la 7.0(3)I7(4). Los switches de Nexus 3600 Platform se ven afectados en versiones de software anteriores a la 7.0(3)F3(5). Los switches de Nexus 9000 Series en Stand se ven afectados en versiones de software anteriores a la 7.0(3)F3(5).
