The vulnerability is due to insufficient restrictions on Lua function calls within the context of user-supplied Lua scripts. An attacker with valid administrative credentials could exploit this vulnerability by submitting a malicious Lua script. When this file is processed, an exploitable buffer overflow condition could occur. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying Linux OS of the affected device."},{"lang":"es","value":"Una vulnerabilidad en la implementación del intérprete Lua que es integrado en Cisco IOS XE Software, podría permitir a un atacante local autenticado ejecutar código arbitrario con privilegios root en el sistema operativo (SO) subyacente Linux de un dispositivo afectado. La vulnerabilidad es debido a restricciones insuficientes en las llamadas a funciones de Lua dentro del contexto de los scripts de Lua suministrados por el usuario. Un atacante con credenciales administrativas válidas podría explotar esta vulnerabilidad mediante el envío de un script Lua malicioso. Cuando se procesa este archivo, podría ocurrir
