Workaround instructions to address CVE-2021-44228 and CVE-2021-45046 in vRealize Automation 7.6

Products

• VMware Aria Suite

Issue/Introduction

Notice: On December 14, 2021 the Apache Software Foundation notified the community that their initial guidance for CVE-2021-44228 workarounds was not sufficient. We believe the instructions in this article to be an effective mitigation for CVE-2021-44228 and CVE-2021-45046, but in the best interest of our customers we must assume this workaround may not adequately address all attack vectors.

Environment

VMware vRealize Automation 7.6.x

Resolution

• The workarounds described in this document are meant to be a temporary solution only.
• Upgrades documented in the aforementioned advisory should be applied to remediate CVE-2021-44228 when available.

Workaround:

Note:  If you have applied the workaround from this KB article prior to December 17, 2021, you will need to re-run through to ensure you have the latest fixes as outlined by Apache.

Note:  KB is only applicable for versions up to 7.6 HF 24.

Note: The following procedure requires downtime of the system due to service restarts.

Prerequisites

• Backup the vRA appliance nodes.
• You have access to root user and password
• You have SSH or console access to each virtual appliance.

Procedure

Note: Steps #2 - #3 apply to the embedded vRealize Orchestrator 7.6 instance.  For external instances, see Workaround instructions to address CVE-2021-44228 and CVE-2021-45046 in vRealize Orchestrator 7.6.

SSH into each vRA appliance node and run the following steps:

1. Stop the vco-configurator service on each vRA node:

   service vco-configurator stop

2. Run the following command to update vRO configuration on each vRA node:

Validation

To validate that the workaround has succeeded, take the following steps on all nodes:

1. Verify that all vco and vcac processes are running with the java property log4j2.formatMsgNoLookups=true

ps aux | grep -i java | grep Dlog4j2.formatMsgNoLookups=true

2. Monitor the log /var/log/vco/app-server/vco_log4j_cve.log file, until you see 'Patching done.'
3. Run the command below to verify that the JndiLookup.class is not present in any log4j jar file for 2.x versions:

find / -xdev -type f -name 'log4j-core-2*jar' -exec sh -c '/usr/bin/unzip -l "{}" | grep -q org/apache/logging/log4j/core/lookup/JndiLookup.class && echo Found in file: {}' \;

The scripting was successful if the output is empty or contains only log4j version 2.17 and above.

Note: If the above validation detects anything in the /var/lib/vco/migration-cli/ location - this directory can be safely removed, as it is a non-essential cli tool used only during vRO migration.
