Summary:
Dell EMC Isilon OneFS 8.2.0 and later contains a workaround for a SyncIQ a vulnerability that affects all current versions of OneFS through OneFS 8.2.2. This vulnerability may potentially be exploited by malicious users to compromise the affected system.
CVE-2020-5328
Dell EMC Isilon OneFS (all current versions) contain an unauthorized access vulnerability due to a lack of thorough authorization checks in SyncIQ. This is only impactful if the SyncIQ feature is licensed, and the encrypted syncs option is not marked as required. When this happens, loss of control of the cluster may occur.

Scenario |
OneFS versions prior to 8.2.0 |
OneFS 8.2.0 and later |
SyncIQ is not licensed |
No change needed |
No change needed |
SyncIQ is licensed but not used |
Disable SyncIQ:
isi sync settings modify -service=Off |
Disable SyncIQ:
isi sync settings modify -service=Off |
SyncIQ is licensed and used |
|
isi sync setting mod --encryption-required=True |
Adjustment to lessen the vulnerability impact | The cluster can be left in a less vulnerable state by enabling a SyncIQ password. For more information see KB article 542907: Link Error Dell EMC Isilon OneFS: How to use a PSK when using SyncIQ since 7.0.0 on the Customer support site. |
Note: Because SyncIQ encryption requires mutual authentication SSL handshakes, each cluster must specify its own identity certificate and the CA certificate of the peer. For more information, see the SyncIQ traffic encryption section of the OneFS 8.2.1 Web Admin Guide.
