Descriptions

Multiple vulnerabilities in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to access the underlying operating system with root privileges. These vulnerabilities are due to insufficient input validation of certain CLI commands. An attacker could exploit these vulnerabilities by authenticating to the device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to access the underlying operating system with root privileges.

Múltiples vulnerabilidades en la CLI del Software Cisco IOS XE SD-WAN, podrían permitir a un atacante local autenticado acceder al sistema operativo subyacente con privilegios root. Estas vulnerabilidades son debido a una comprobación insuficiente de la entrada de determinados comandos de la CLI. Un atacante podría explotar estas vulnerabilidades al autenticarse en el dispositivo y enviar una entrada diseñada a la CLI. El atacante debe estar autenticado como usuario administrativo para ejecutar los comandos afectados. Una explotación con éxito podría permitir al atacante acceder al sistema operativo subyacente con privilegios root
