Descriptions
A vulnerability in the CLI of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system (OS) of an affected device. The vulnerability is due to insufficient input validation of commands that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input for specific commands. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges. To exploit this vulnerability, an attacker must have valid administrator-level credentials.
Una vulnerabilidad en la CLI del Software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante autenticado local ejecutar comandos arbitrarios en el sistema operativo (SO) subyacente de un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de entrada de los comandos suministrados por el usuario. Un atacante podría explotar esta vulnerabilidad al autenticarse en un dispositivo y enviar una entrada diseñada para comandos específicos. Una explotación con éxito podría permitir al atacante ejecutar comandos en el sistema operativo subyacente con privilegios root. Para explotar esta vulnerabilidad, un atacante debe tener credenciales válidas de nivel de administrador
