Technical Advisory #15 - cross site scripting CVE on PowerScale 

cross site scripting vulnerabilities in CVE-2017-8024 requires a patch from PowerScale available for certain PowerScale release streams.  This patch also requires disabling HTTP authentication which will affect Eyeglass directly.   Eyeglass will not able to login to perform any DR functions.   An updated version 2.5.3 will include alternate authentication solution for PowerScale to allow this complete CVE procedures to be applied.   Partial implementation is possible by applying the path to PowerScale without disabling the HTTP authentication on the cluster

Technical Advisory #16 - Config Sync may skip steps on Error

This issue is present in > 1.9.4 and can result in SMB shares and export not synced to DR if an object cannot be synced remaining objects are not attempted.  

Resolution:  Clear the error and all unsync changes will be synced successfully.  A work around exists and requires a support case opened for instructions.   This has been fixed in release 2.5.3 once it is GA.  We will also be releasing a patch to 2.5.2 that corrects this issue. The patch can be downloaded from the download page on located on the support site and will require download of the 2.5.2 offline installer and upgrading from 2.5.2 to latest build of 2.5.2 for an existing installation.

Technical Advisory #17 - PowerScale CSRF Authentication is not compatible with Smartconnect and API services Affects Eyeglass releases 2.5.3 and later  

NOTE: Only 2.5.3 and later supports a cluster with CSRF enabled.

Issue: PowerScale does NOT support multi node cluster aware CSRF sessions for authentication and is NOT compatible with Smartconnect FQDN method #1.  This is known limitation of PowerScale CSRF implementation.

Impact: None. SSIP is fully supported with many deployments using this method.  The load balancing of FQDN has some potential to expose issues on various nodes in the cluster and a minor performance improvement for large object customers.

Resolution:  To support CSRF on PowerScale requires settings that disable basic HTTPS authentication and uses session tokens for authentication.  This requires Eyeglass to use the SSIP in the management access zone due to above PowerScale limitation.

1. If you have added clusters to Eyeglass with FQDN (How to check:  Open Inventory Icon, right click the cluster and select Edit to determine how Eyeglass was added).
2. Open Jobs icon, record all policy states in all sections of this window. You will need to re-enable these policies and enable DFS mode based on your records from this step.
3. Delete the cluster (right click menu on the cluster name, chose the delete option)
   1. Repeat the delete for each cluster listed in the inventory icon
   2. Re-add the cluster with the SSIP in the system access zone, enter eyeglass service account name used before and password
   3. Repeat for each cluster Note:  more than one cluster can be added before submitting the inventory job
   4. Open Jobs Icon, then running jobs tab,  wait for initial inventory to complete
   5. Once complete click on job definition tab and enable all jobs based on the recorded configurations from the step above.
   6. You may also need to enable DFS mode (How to enable DFS mode
   7. Use the bulk actions menu to enable the jobs (How to enable jobs)
   8. Then wait 5 minutes and verify all jobs are green
   9. If any errors, please open a support case.

Technical Advisory #18 - Ransomware Defender ECA cluster without Internet access potential for false positives

Issue: In release 2.5.3 of Ransomware Defender a threat detector will sometimes match files that should not be considered Ransomware only when the ECA cluster does not have Internet access.

Impact: False positive detection of some users depending on the IO pattern.

Resolution:  A new build of 2.5.3 with number 18257 is available for download now that addresses this issue, without any requirement to connect ECA clusters to the Internet. 

1. Instructions to apply patch
2. Open a support case and request assistance to apply the patch.

Technical Advisory #19 - SMB Data Integrity corner case can leave Deny permission on some or all shares

Issue:  Normal configuration sync runs every 5 minutes and under some conditions may detect the Deny everyone permission used by the Data Integrity DR Assistant failover feature and sync it to the DR cluster before the deny is removed by the failover process.  This is a corner case that has rare. 

Impact:  After a failover some SMB shares may be left with a deny everyone permission blocking access to users.

Solution: Manually remove the Deny Everyone permission on the affected shares.  

Solution to Use SMB Data Integrity Feature:   

1. Disable the config Sync Job before the failover
   1. using SSH to the Eyeglass appliance run:
   2. igls admin schedules set --id Replication --enabled false
      
2. After the failover is complete
   1. igls admin schedules set --id Replication --enabled true
      

Resolution:  A new build of 2.5.4 with number 18275 has been released to address this issue.

Technical Advisory #20 - PowerScale Auditing incorrectly records audit events for paths that do not exist on the cluster when SMB share is mounted with subfolders with a case that does not match the file system

Issue:  Mounting below the SMB share of a file system path of \ifs\data\temp and the mount example \\dnsname\sharename\TEMP  where temp is a subfolder will be audited incorrectly and recoreded as an audit event that does not exist in the file system.  The audit event will be incorrectly created as /ifs/data/TEMP even though this path does not exist in the file system.   PowerScale file system is case senstive.   

NOTE:  If all SMB share mounts mount the share only and does not include subfolders this issue will not be seen, or if the subfolders of the mount matches the case of the actual file system.  NOTE: Onefs is a case senstive file system,  NFS does not have this issue and denies mounts if the case does not match the actual file system case. NOTE: Mounting the SMB share only, will allow Windows OS to auto correct the case when browsing the file system with explorer or command prompt and will not have this issue.

Best Practise:  If sub share mounts are needed , the case should match the file system path.

Work Around: With Easy Auditor start searches from the share path, not the sub path, only if you know you have mismatched mounts with sub folders.

PowerScale fix for this bug:  No known fix planned

Technical Advisory #21 - OneFS CLI command bug fails to exit ram 

Description of issue:  Onefs CLI command with a bug fails to exit after execution in some scenarios; the conditions for this to occur are unknown at this time.

A Onefs CLI command isi status has a bug that can cause the command to fail to exit memory.  A patch exists from PowerScale support for this bug.  This command is used by Eyeglass to collect node usage data and runs on a schedule.  Due to this bug, it is possible that this command may not exit ram and each new execution of the command will consume more ram on PowerScale nodes.  

As a proactive measure the following steps should be followed to avoid the potential of ram usage consumption due to the Onefs CLI bug.

Impact To Eyeglass DR:  No impact by following these steps, no loss of DR functionality.

Side Effects:  An alarm may be raised about CLI data incomplete which can be ignored.

Steps to follow:

Remove these lines from your sudoer file or place a # at the front of the line and save it.  

1. SSh to PowerScale
2. Edit the sudoer file using the PowerScale isi_visudo command.
3. Sudo file opens in vi editor.  place # in front of these lines
4. Save the file with :wq
5. eyeglass ALL=(ALL) NOPASSWD: /usr/bin/isi_for_array isi status*
6. eyeglass ALL=(ALL) NOPASSWD: /usr/bin/isi status*

Technical Advisory #22 - Onefs 8.2 Does not support REST API or SSH SSIP connections from Eyeglass

1. Onefs releases 8.2 and later no longer support API connections or SSH connections needed by Eyeglass.  If you are planning an upgrade to 8.2 the following steps should be completed before your Onefs Upgrade to 8.2.
   1. Upgrade to 2.5.5 latest release number - Upgrade guide.
   2. Change the ip address used to add the cluster to Eyeglass to use a node IP in a system zone pool.  The pool should be dynamic mode to ensure the IP will failover to other nodes.
   3. This is done with the Inventory Icon, right click , edit , change the ip address, re-enter password and save.
   4. Verify by opening the jobs icon and selecting a job with a check box, bulk actions , run now.  Then monitor in the running jobs icon.
   5. For more detailed steps open a support case with support to assist or provide health check after the change has been made.

Technical Advisory #23 - 2.5.6 Patch 1 Addresses failover Scenario's that can delay some steps from starting immediately

1. Some scenario's can cause delays in failover jobs starting to execute steps due to timeouts. An updated 2.5.6 patch addresses this issue.
2. Recommendation:  Upgrade to patch one following the offline upgrade steps here or open a support case for assistance.
3. Full release notes on patch 1 that includes additional fixes is available here 

Technical Advisory #24 Config Only Migration Job deletes shares and exports on the Destination Access Zone

In 2.5.6 build 84 or earlier this feature is a mirror mode and will remove any overlapping or non matching configuration data found on the target path or below. This will be changed in a patch release to default to merge mode and will leave all target configuration data as is and copy only new configuration to the target path.  Note that a config only migration job will run on regular configuration replication cycle and if you are in this situation it should be deleted as it will delete any share or export you recreated to solve this problem on the next run.

Technical Advisory #25 OneFS fails to create Quotas with corrupt configuration

During failover Quotas with corrupt / invalid configuration on the failover source cluster will be blocked from being created on the target cluster by OneFS.  In the Superna Eyeglass failover log this will display as a quota error.  For example a Quota on the source cluster with both Advisory and Advisory Threshold percentage configuration will be blocked by OneFS from being created on the target cluster with the message that only on advisory threshold option is supported.  It is unknown how a Quota would enter this state on the source cluster and Dell EMC should be contacted for troubleshooting/resolution of the corrupt quota configuration issue.

Work Around Patch Available from Dell

Technical Advisory #32 Onefs version 9.3 and later - papi session API bug affecting Golden Copy and Search & Recover

Overview

The session authentication behavior was changed in 9.3 and later Onefs releases and the change is not backwards compatible with previous session authentication.  This bug causes authentication sessions to fail which causes API calls to the cluster to fail.

Work Around

Set the session timeout values using the root user to a longer value

Onefs Patch Availability 

Technical Advisory #33 - Eyeglass REST API allows unauthenticated access

Using an API token that does not match a token in the authorized list, an unauthenticated user can access routes on the Eyeglass REST API by including a made-up token. All API routes are affected.

Affected Products:

All Eyeglass DR, Ransomware Defender, Easy Auditor, and Performance Auditor versions from 2.5.9-22219 through 2.5.11-23110

Impact: No risk to data on Powerscale, no risk to any configuration information within any Eyeglass product

Remediation

To temporarily block access to all but the heartbeat routes on the REST API:

1. edit the /etc/lighttpd/lighttpd.conf file

2. add the following block of text on line 419

$HTTP["url"] =~ "/sera/.*" {

  $HTTP["url"] !~ "/sera/v1/(healthcheck|ransomware/heartbeat)" {

    url.access-deny = ("")

  }

}

 3. Save the file

 4. Restart the lighttpd service: systemctl restart lighttpd

Patching

A new build of Eyeglass Release 2.5.11 with version number 23111 or higher is expected to be released in the coming 24 hours, that re-enables the authentication on the necessary routes.
