El componente Moby daemon (`dockerd`), que se desarrolla como moby/moby, se conoce com\u00fanmente como *Docker*. El modo Swarm, que se compila y entrega de forma predeterminada en \\\"dockerd\\\" y, por lo tanto, est\u00e1 presente en la mayor\u00eda de las principales versiones de Moby, es un orquestador de contenedores simple e integrado que se implementa mediante una combinaci\u00f3n de SwarmKit y c\u00f3digo de red de soporte. El controlador de red \\\"superpuesto\\\" es una caracter\u00edstica central del modo Swarm, que proporciona LAN virtuales aisladas que permiten la comunicaci\u00f3n entre contenedores y servicios en todo el cl\u00faster. Este controlador es una implementaci\u00f3n/usuario de VXLAN, que encapsula tramas de capa de enlace (Ethernet) en datagramas UDP que etiquetan la trama con los metadatos de VXLAN, incluido un ID de red VXLAN (VNI) que identifica la red superpuesta de origen. Adem\u00e1s, el controlador de red superpuesta admite un modo cifrado opcional, desactivado de forma predeterminada, que resulta especialmente \u00fatil cuando los paquetes VXLAN atraviesan una red que no es de confianza entre nodos. Las redes superpuestas cifradas funcionan encapsulando los datagramas VXLAN mediante el uso del protocolo IPsec Encapsulating Security Payload en modo Transporte. Al implementar la encapsulaci\u00f3n IPSec, las redes superpuestas cifradas obtienen propiedades adicionales de autenticaci\u00f3n de origen mediante prueba criptogr\u00e1fica, integridad de datos mediante suma de verificaci\u00f3n y confidencialidad mediante cifrado.Al configurar un endpoint en una red superpuesta cifrada, Moby instala tres reglas de iptables (firewall del kernel de Linux) que aplican IPSec tanto entrante como saliente. Estas reglas se basan en la extensi\u00f3n iptables `u32` proporcionada por el m\u00f3dulo del kernel `xt_u32` para filtrar directamente el campo VNI de un paquete VXLAN, de modo que las garant\u00edas IPSec se puedan aplicar en redes superpuestas cifradas sin interferir con otras redes superpuestas u otros usuarios de VXLAN. Una regla de iptables designa datagramas VXLAN salientes con un VNI que corresponde a una red superpuesta cifrada para encapsulaci\u00f3n IPsec. Las redes superpuestas cifradas en las plataformas afectadas transmiten silenciosamente datos no cifrados. Como resultado, las redes \\\"superpuestas\\\" pueden parecer funcionales, pasando el tr\u00e1fico como se esperaba, pero sin ninguna de las garant\u00edas esperadas de confidencialidad o integridad de los datos. Es posible que un atacante ubicado en una posici\u00f3n confiable en la red lea todo el tr\u00e1fico de aplicaciones que se mueve a trav\u00e9s de la red superpuesta, lo que resulta en secretos inesperados o divulgaci\u00f3n de datos del usuario. Por lo tanto, debido a que muchos protocolos de bases de datos, API internas, etc. no est\u00e1n protegidos por una segunda capa de cifrado, un usuario puede utilizar redes superpuestas cifradas Swarm para proporcionar confidencialidad, que debido a esta vulnerabilidad ya no est\u00e1 garantizada. Los parches est\u00e1n disponibles en las versiones 23.0.3 y 20.10.24 de Moby. Como las versiones 20.10 de Mirantis Container Runtime tienen numeraci\u00f3n diferente, los usuarios de esa plataforma deben actualizar a la versi\u00f3n 20.10.16. Algunos workarounds est\u00e1n disponibles.
