All sites where multiple domains are created from the same instance of WebLogic Server are susceptible to this vulnerability.

If multiple domains are created on the same machine by the same WebLogic Server instance, the created domains are accessible to any administrative users of any of the domains.

This documentation update describes the issue and suggests that domains be created on a different machine or with a different WebLogic Server instance or that OS file permissions be used to protect the domains from Administrative users of the other domains. See the Security Action labeled "Control access to multiple domains" in the following locations:
