Descriptions

A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the underlying file system of an affected system. This vulnerability is due to insufficient validation of the user-supplied input parameters of a specific CLI command. An attacker could exploit this vulnerability by issuing that command with specific parameters. A successful exploit could allow the attacker to overwrite the content in any arbitrary files that reside on the underlying host file system.

Una vulnerabilidad en la CLI de Cisco SD-WAN Software, podría permitir a un atacante local autenticado sobrescribir archivos arbitrarios en el sistema de archivos subyacente de un sistema afectado. Esta vulnerabilidad es debido a una comprobación insuficiente de los parámetros de la entrada proporcionados por el usuario de un comando CLI específico. Un atacante podría explotar esta vulnerabilidadal al emitir ese comando con parámetros específicos. Una explotación con éxito podría permitir al atacante sobrescribir el contenido de cualquier archivo arbitrario que resida en el sistema de archivos del host subyacente
