Prior to version 1.7.45, Grav validates accessible functions through the Utils::isDangerousFunction function, but does not impose restrictions on twig functions like twig_array_map, allowing attackers to bypass the validation and execute arbitrary commands. Twig processing of static pages can be enabled in the front matter by any administrative user allowed to create or edit pages. As the Twig processor runs unsandboxed, this behavior can be used to gain arbitrary code execution and elevate privileges on the instance. Upgrading to patched version 1.7.45 can mitigate this issue.\n"}, {"lang": "es", "value": "Grav es un sistema de gesti\u00f3n de contenidos de archivos planos de c\u00f3digo abierto. Antes de la versi\u00f3n 1.7.45, Grav valida funciones accesibles a trav\u00e9s de la funci\u00f3n Utils::isDangerousFunction, pero no impone restricciones a funciones de twig como twig_array_map, lo que permite a los atacantes eludir la validaci\u00f3n y ejecutar comandos arbitrarios. El procesamiento Twig de p\u00e1ginas est\u00e1ticas puede ser habilitado en la portada por cualquier usuario administrativo autorizado a crear o editar p\u00e1ginas. Como el procesador Twig se ejecuta sin entorno de pruebas, este comportamiento se puede utilizar para obtener la ejecuci\u00f3n de c\u00f3digo arbitrario y elevar los privilegios en la instancia.
