Purpose
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.
Â
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.
Â
Workaround
Prerequisites
Backup the vRA appliance nodes
Snapshots ( My vRealize Automation environment is managed by vRSLCM so i'll use it to take snapshots )
Snapshot is now complete
Let's now move to the actual procedure of workaround implementation
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 in vRealize Orchestrator 7.
SSH into each vRA appliance node and run the following steps:
Step:1
Stop the vco-configurator service on each vRA node
Step:2
Run the following command to update vRO configuration on each vRA node:

Restart the services on each vRA Node
service elasticsearch restart
service vco-server status | grep PID && service vco-server restart
service vco-configurator start
service vcac-server restart
Note:
Below command can be used to stop and start all the services systematically. Not mentioned in the knowledge base article but can be followed
vcac-vami service-manage stop vco-configurator vco-server vcac-server horizon-workspace hzn-dots elasticsearch
vcac-vami service-manage start elasticsearch hzn-dots horizon-workspace vcac-server vco-server vco-configuratorStep:6 ( not present in the kb , an extra step just for validation )
Verify if all vRealize Automation services are registered
curl --insecure -f -s -H "Content-Type: application/json" "https:/$HOSTNAME/component-registry/services/status/current?limit=200" | sed "s/}/\n/g" | grep -E -o ".serviceName.*serviceInitializationStatus.[^,]*" | sed "s/\"serviceTypeId.*,//g" | sed -e "s/\"//g" -e "s/:/=/g" -e "s/,/, /" | sed -e "s/serviceName\|serviceInitializationStatus\|=\|,\|null//g" | column -t | sort | cat -n

Validation
To validate that the workaround has succeeded, take the following steps on all nodes
Verify that all vco and vcac processes are running with the java property "log4j2.formatMsgNoLookups=true":
Monitor the log /var/log/vco/app-server/vco_log4j_cve.log file, until you see 'Patching done.'
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 org/apache/logging/log4j/core/lookup/JndiLookup.class' \;The command output will be empty if the scripting was successful.

This completes implementation of the workaround in vRealize Automation 7.6
