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.

  • Unauthorized Access vulnerability

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.

CVSS v3.1 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

受影響的產品與補救措施

Affected products:   
Dell EMC Isilon OneFS versions through OneFS 8.2.2

Workaround:   

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: 

  1. On the cluster, log in as SSH.

  2. Run the following command to disable SyncIQ: 

isi sync settings modify  -service=Off

Disable SyncIQ:   

  1. On the cluster, log in as SSH.                     

  2. Run the following command to disable SyncIQ:

isi sync settings modify  -service=Off

 

SyncIQ is licensed and used

  1. Upgrade to OneFS 8.2.0 on all clusters that are using SyncIQ.

  2. Follow the workaround instructions in For OneFS versions 8.2.0 and later in the next cell.







 

  1. Enable SyncIQ encryption for each impacted cluster. For more details, see the Configure certificates procedure described in the Data Encryption with SyncIQ chapter of the OneFS 8.2.0 CLI Administration Guide, and the steps that need to be run on each policy to enable encryption.

  2. Create a SyncIQ policy to enable encryption, as described in the Create encrypted SyncIQ policies procedure of the guide.

  3. Force SyncIQ encryption, as described in the same procedure.

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.
