Article Number: 000200962
CVE ID: CVE-2022-31231
Severity: Medium
Who should run this procedure?
Dell requests this procedure of upgrading xDoctor and installation of the patch be done by Customers. This is the quickest and safest method as it avoids prolonged exposure to this vulnerability. All the steps are detailed in this KB. There is also a video guide which can be followed to accompany this KB which resides at below link.
Impact of procedure:
Expect possible I/O timeouts while dataheadsvc services are restarted node by node. Applications should be accessing the cluster via a Load balancer and must be able to handle the I/O timeout. A maintenance window is advised when performing this procedure.
CAS only buckets Exception:
If all buckets on a system are exclusively CAS highlighted below then it is not affected by this security vulnerability. It is therefore not necessary to apply the patch and this KB does not have to be followed.
Command: svc_bucket list
Example:
admin@ecs-n1:~> svc_bucket list
svc_bucket v1.0.33 (svc_tools v2.5.1) Started 2022-07-08 08:49:11
Bucket Temp
Replication Owner Owner API FS Versioning Failed
Bucket Name Namespace Group User VDC Type Enabled Enabled (TSO)
cas_bucket region_ns RG1 casuser VDC1 CAS false Disabled False
cas_bu region_ns RG1 cas_obj VDC1 CAS false Disabled False
test region_ns RG1 test1 VDC1 CAS false Disabled False
test_cas region_ns RG1 test_cas VDC1 CAS false Disabled False
test_bkt_cas region_ns RG1 user_test VDC1 CAS false Disabled False
Friday_cas region_ns RG1 Friday_cas VDC1 CAS false Disabled False
Time taken for the activity (Approximately):
A 60 second delay is set by default per node between service restarts. The number of nodes in a Virtual Data Center (VDC) multiplied by 60 seconds + 30 minutes for preparation, service stabilization, and post checks needed.
Examples:
An 48 node VDC system can take approximately 80 mins:
60 seconds X 48 (Number of VDC nodes) + 30 minutes (preparation) = 80 mins approx.
An 8 node VDC system can take approximately 40 mins:
60 seconds X 8 (Number of VDC nodes) + 30 minutes (preparation) = 40 mins approx.
Frequently Asked Questions (FAQ):
Q: Is the patch part of the xDoctor release?
A: The patch install script is part of xDoctor release 4.8-84 and higher. Instructions for the download of xDoctor and execution of patch install are in the resolution steps.
Q: Can I update multiple VDCs in parallel?
A: No, patch 1 VDC at a time.
Q: If I upgrade ECS after running this procedure, do I rerun the procedure post upgrade?
A: No, if upgrading to a code version specified in DSA-2022-153 which has the permanent fix. Yes, if upgrading to a code version not specified in this same DSA.
Q: Does the patch need to be reapplied on a system where it was previously installed after a node replacement, reimage, or expansion?
A: No, if the VDC is at the code version that is specified in DSA-2022-153 which has the permanent fix. Yes, if doing any of these actions against a VDC running a code version not specified in this same DSA. Where the patch is required for these scenarios, the Dell engineer in question will contact to inform that update is required.
Q: What if I'm only using legacy users and not using IAM?
A: Customers need to apply the patch regardless if using only legacy users and not IAM.
Q: What user should you be logged in as to execute all commands in this KB?
A: admin
Q: Does svc_patch have to be run on all racks or with a specialized MACHINES file where multiple racks in a VDC?
A: No, it autodetects if multiple racks exist and patches all nodes on all racks on that VDC.
Q: I notice the target xDoctor release is no longer 4.8-84.0. Why?
A: xDoctor releases occur frequently so it is always recommended to upgrade to highest released version. If however you have previously ran the fix using 4.8-84.0 then system is fully protected against the vulnerability and does not need to be rerun.
Resolution Summary:
Upgrade your ECS xDoctor software to latest Version available.
