Name of the Vulnerable Software and Affected Versions mailcow versions prior to 2024-01c

Description A security issue has been identified in mailcow, a dockerized email package. This issue 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, which 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.

Recommendations For versions prior to 2024-01c, update to version 2024-01c or later to resolve the issue. As a temporary workaround, consider implementing additional iptables/nftables rules to drop packets for Docker containers on vulnerable ports, where the input interface is not br-mailcow and the output interface is br-mailcow. Restrict access to the exposed ports to minimize the risk of exploitation.
