"The version of the Docker Engine (Moby) installed on the remote host is prior to 23.0.15 or 28.0.0. When firewalld 
reloads, Docker fails to re-create iptables rules that isolate bridge networks, allowing any container to access all 
ports on any other container across different bridge networks on the same host. This breaks network segmentation 
between containers that should be isolated, creating significant risk in multi-tenant environments. Only containers 
created with --internal networks remain protected. Workarounds include reloading firewalld and either restarting the 
docker daemon, re-creating bridge networks, or using rootless mode. Maintainers anticipate a fix for this issue in 
version 25.0.13.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
