Descriptions

A vulnerability in the CLI of Cisco NX-OS Software and Cisco FXOS 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. Firepower 4100 Series Next-Generation Firewalls are affected running software versions prior to 2.2.2.91, 2.3.1.110, and 2.4.1.222. Firepower 9300 Security Appliance are affected running software versions prior to 2.2.2.91, 2.3.1.110, and 2.4.1.222. MDS 9000 Series Multilayer Switches are affected running software versions prior to 6.2(25) and 8.3(1). Nexus 3000 Series Switches are affected running software versions prior to 7.0(3)I4(9) and 7.0(3)I7(5). Nexus 3500 Platform Switches are affected running software versions prior to 7.0(3)I7(5). Nexus 3600 Platform Switches are affected running software versions prior to 7.0(3)F3(5). Nexus 2000, 5500, 5600, and 6000 Series Switches are affected running software versions prior to 7.1(5)N1(1b) and 7.3(4)N1(1). Nexus 7000 and 7700 Series Switches are affected running software versions prior to 6.2(22), 7.3(3)D1(1), 8.2(3). Nexus 9000 Series Switches in Standalone NX-OS Mode are affected running software versions prior to 7.0(3)I4(9) and 7.0(3)I7(5). Nexus 9500 R-Series Line Cards and Fabric Modules are affected running software versions prior to 7.0(3)F3(5).

Una vulnerabilidad en la CLI del software NX-OS de Cisco y de Cisco FXOS 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 del administrador válidas para explotar esta vulnerabilidad. Firepower 4100 Series Next-Generation Firewalls se ven afectados en versiones anteriores a las 2.2.2.91, 2.3.1.110 y 2.4.1.222. Firepower 9300 Security Appliances se ven afectados en versiones anteriores a las 2.2.2.91, 2.3.1.110 y 2.4.1.222. Los switches de MDS 9000 Series Multilayer se ven afectados en versiones anteriores a las 6.2(25) y 8.3(1). 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(5). Los switches de Nexus 3500 Platform se ven afectados en versiones de software anteriores a la 7.0(3)I7(5). Los switches de Nexus 3600 Platform se ven afectados en versiones de software anteriores a la 7.0(3)F3(5).
