En resumen
Una falla en la interfaz de línea de comandos de Cisco NX-OS permite que administradores inyecten comandos maliciosos que se ejecuten con privilegios de root. Un atacante con credenciales de admin puede eludir validaciones de entrada para ganar control total del sistema operativo subyacente.
Detalle técnico
Vulnerabilidad de inyección de comando en CLI de Cisco NX-OS debido a validación insuficiente de argumentos. Un atacante autenticado con credenciales de Administrador puede inyectar entrada manipulada en comandos de configuración específicos para ejecutar comandos arbitrarios del SO con privilegios de root. La explotación requiere acceso administrativo; algunos modelos Nexus (3000, 7000 v8.1+, 9000 standalone) no son afectados ya que permiten acceso bash-shell administrativo.
Resumen generado y traducido por IA a partir de la descripción oficial.
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated user in possession of Administrator credentials to execute arbitrary commands as root on the underlying operating system of an affected device.
This vulnerability is due to insufficient validation of arguments that are passed to specific configuration CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected configuration CLI command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of root.
Note: To successfully exploit this vulnerability on a Cisco NX-OS device, an attacker must have Administrator credentials. The following Cisco devices already allow administrative users to access the underlying operating system through the bash-shell feature, so, for these devices, this vulnerability does not grant any additional privileges:
Nexus 3000 Series Switches
Nexus 7000 Series Switches that are running Cisco NX-OS Software releases 8.1(1) and later
Nexus 9000 Series Switches in standalone NX-OS mode
