Enterprise Vault.cloud core components do not use the Log4j2 component and therefore are not affected by this vulnerability. However, Enterprise Vault.cloud uses the third-party component called Elasticsearch version 7.12.1 which internally uses Log4j 2x.
As an additional precaution recommend by Elastic, we have already set JVM Option to true: Dlog4j2.formatMsgNoLookups=true
NOTE: Veritas Advanced Supervision (VAS), Veritas Information Classifier (VIC), and Merge1 are not impacted by this vulnerability and require no mitigation when used in association with Enterprise Vault.cloud.
There are no further mitigation steps required for Enterprise Vault.cloud.
