Este problema afecta a Apache Airflow desde la versi\u00f3n 2.8.2 hasta la 2.8.3. El controlador de tareas de archivos locales de Airflow en Airflow configur\u00f3 incorrectamente permisos para todas las carpetas principales de la carpeta de registro, en la configuraci\u00f3n predeterminada agrega acceso de escritura al grupo de carpetas de Unix. En el caso de que Airflow se ejecute con el usuario root (no recomendado), agreg\u00f3 permiso de escritura grupal a todas las carpetas hasta la ra\u00edz del sistema de archivos. Si sus archivos de registro est\u00e1n almacenados en el directorio de inicio, estos cambios de permisos pueden afectar su capacidad para ejecutar operaciones SSH despu\u00e9s de que su directorio de inicio se pueda escribir en grupo. Este problema no afecta a los usuarios que usan o ampl\u00edan Airflow utilizando im\u00e1genes de referencia oficiales de Airflow Docker (https://hub.docker.com/r/apache/airflow/); de todos modos, esas im\u00e1genes requieren tener configurado el permiso de escritura grupal. Solo se ver\u00e1 afectado si instala Airflow usando la instalaci\u00f3n local/virtualenv u otras im\u00e1genes de Docker, pero el problema no tiene ning\u00fan impacto si los contenedores de Docker se usan seg\u00fan lo previsto, es decir, cuando los componentes de Airflow no comparten contenedores con otras aplicaciones y usuarios. Adem\u00e1s, no deber\u00eda verse afectado si su umask es 002 (escritura en grupo habilitada); este es el valor predeterminado en muchos sistemas Linux. Recomendaci\u00f3n para usuarios que usan Airflow fuera de los contenedores: * si est\u00e1 usando root para ejecutar Airflow, cambie su usuario de Airflow para usar no root * actualice Apache Airflow a 2.8.4 o superior * Si prefiere no actualizar, puede cambiar los https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#file-task-handler-new-folder-permissions a 0o755 (valor original 0o775). * si ya ejecut\u00f3 tareas de Airflow antes y su umask predeterminada es 022 (escritura grupal deshabilitada), debe detener los componentes de Airflow, verificar los permisos de AIRFLOW_HOME/logs en todos sus componentes y todos los directorios principales de este directorio y eliminar el acceso de escritura grupal para todos los directorios principales\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"NONE\",\"baseScore\":5.3,\"baseSeverity\":\"MEDIUM\"},\"exploitabilityScore\":1.6,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"security@apache.org\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-281\"}]}],\"references\":[{\"url\":\"http://www.openwall.com/lists/oss-security/2024/03/26/2\",\"source\":\"security@apache.org\"},{\"url\":\"https://github.com/apache/airflow/pull/37310\",\"source\":\"security@apache.org\"},{\"url\":\"https://lists.apache.org/thread/8khb1rtbznh100o325fb8xw5wjvtv536\",\"source\":\"security@apache.org\"}]}}"
