The underlying weakness: Binding to an Unrestricted IP Address
The product assigns the address 0.0.0.0 for a database server, a cloud service/instance, or any computing resource that communicates remotely.
How developers prevent this class of flaw
- Assign IP addresses that are not 0.0.0.0.
- Unwanted connections to the configured server may be denied through a firewall or other packet filtering measures.
