Security Bulletin: An unauthenticated user can determine whether the default superuser password has been changed on IBM SAN Volume Controller, IBM Storwize, IBM FlashSystem and IBM Storage Virtualize products

Summary

An unauthenticated user can determine whether the default superuser password has been changed on IBM SAN Volume Controller, IBM Storwize, IBM FlashSystem and IBM Storage Virtualize products. This only affects the 8.3.1 release as it is impossible for the default password to still be configured on an active system running later releases, since the user must change this either as part of first time setup or prior to upgrading from 8.3.1 or earlier. However, IBM has removed the ability to query this status from all releases listed in the Remediation/Fixes section of this bulletin.
