      "value": "WordPress through 4.9.6 allows Author users to execute arbitrary code by leveraging directory traversal in the wp-admin/post.php thumb parameter, which is passed to the PHP unlink function and can delete the wp-config.php file. This is related to missing filename validation in the wp-includes/post.php wp_delete_attachment function. The attacker must have capabilities for files and posts that are normally available only to the Author, Editor, and Administrator roles. The attack methodology is to delete wp-config.php and then launch a new installation process to increase the attacker's privileges."

      "value": "WordPress hasta la versi\u00f3n 4.9.6 permite que los usuarios Author ejecuten c\u00f3digo arbitrario aprovech\u00e1ndose de un salto de directorio en el par\u00e1metro thumb en wp-admin/post.php que se pasa a la funci\u00f3n unlink en PHP y puede borrar el archivo wp-config.php. Esto est\u00e1 relacionado con la ausencia de validaci\u00f3n de nombres de archivo en la funci\u00f3n wp_delete_attachment en wp-includes/post.php. El atacante debe tener capacidades para archivos y publicaciones que normalmente est\u00e1n disponibles solo para los roles Author, Editor y Administrator. La metodolog\u00eda de ataque es borrar wp-config.php y luego ejecutar un proceso de instalaci\u00f3n nuevo para incrementar los privilegios del atacante."
