Descriptions

mailcow is a dockerized email package, with multiple containers linked in one bridged network. A security vulnerability has been identified in mailcow affecting versions < 2024-01c. This vulnerability potentially allows attackers on the same subnet to connect to exposed ports of a Docker container, even when the port is bound to 127.0.0.1. The vulnerability has been addressed by implementing additional iptables/nftables rules. These rules drop packets for Docker containers on ports 3306, 6379, 8983, and 12345, where the input interface is not `br-mailcow` and the output interface is `br-mailcow`.

mailcow es un paquete de correo electrónico acoplado, con múltiples contenedores vinculados en una red puente. Se ha identificado una vulnerabilidad de seguridad en mailcow que afecta a las versiones &lt;2024-01c. Esta vulnerabilidad potencialmente permite a atacantes en la misma subred conectarse a puertos expuestos de un contenedor Docker, incluso cuando el puerto está vinculado a 127.0.0.1. La vulnerabilidad se ha solucionado mediante la implementación de reglas adicionales de iptables/nftables. Estas reglas descartan paquetes para contenedores Docker en los puertos 3306, 6379, 8983 y 12345, donde la interfaz de entrada no es "br-mailcow" y la interfaz de salida es "br-mailcow".
