Official description
IBM System Storage DS8A00 10.1.3.0 through 10.11.35.0 and IBM DS8900F 89.40.83.0 through 89.44.25.0 could allow an authenticated user to create a user with privileged user roles due to improper privileged defined with unsafe actions.

The underlying weakness: Privilege Defined With Unsafe Actions
A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
