CVE-2018-25122

Nagios XI versions prior to 5.4.13 contain a remote code execution vulnerability in the Component Download page. The download/import handler used unsafe command construction with attacker-controlled input and lacked sufficient validation and output encoding, allowing an authenticated user to inject commands or otherwise execute arbitrary code with the privileges of the application service.

Summary		(es) Las versiones de Nagios XI anteriores a la 5.4.13 contienen una vulnerabilidad de ejecución remota de código en la página de Descarga de Componentes. El gestor de descarga/importación utilizaba una construcción de comandos insegura con entrada controlada por el atacante y carecía de validación y codificación de salida suficientes, lo que permitía a un usuario autenticado inyectar comandos o, de otro modo, ejecutar código arbitrario con los privilegios del servicio de la aplicación.
