Symptoms
Consider the following scenario:
-
In a Microsoft Exchange Server 2010 environment, you create a scoped management role assignment which assigns the Active Directory Permissions or Mail Recipients roles.
-
You assign the role assignment to a role assignee.
-
The role assignee tries to run the Add-ADPermission command against a mailbox that is outside of the role assignment scope.
In this scenario, the role assignee can unexpectedly run the Add-ADPermission command against the out of scope mailbox.
Cause
This issue occurs because there is no Role Based Access Control (RBAC) scope verification when Exchange Server 2010 runs the Add-ADPermission command.
