Problem nedir?

The product assigns the address 0.0.0.0 for a database server, a cloud service/instance, or any computing resource that communicates remotely.

Genişletilmiş açıklama

When a server binds to the address 0.0.0.0, it allows connections from every IP address on the local machine, effectively exposing the server to every possible network. This might be much broader access than intended by the developer or administrator, who might only be expecting the server to be reachable from a single interface/network.
