Official description
IBM App Connect Enterprise 13.0.1.0 through 13.0.8.2 could allow a remote attacker to obtain sensitive information due to binding to an unrestricted IP address.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
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.
