• Affected Log4j Versions: All versions from 2.0-beta9 to 2.16.0 

Impact

Veritas Alta Archiving core components do not use the Log4j2 component and therefore are not affected by this vulnerability.  However, Veritas Alta Archiving uses the third-party component called Elasticsearch version 7.12.1 which internally uses Log4j 2x. 

As officially stated by Elastic in their announcement here, above mentioned vulnerabilities are not exploitable for Elasticsearch 7.12+.   

As an additional precaution recommend by Elastic, we have already set JVM Option to true: Dlog4j2.formatMsgNoLookups=true 

NOTE: Veritas Alta Surveillance, Veritas Alta Classification and Veritas Alta Capture are not impacted by this vulnerability and require no mitigation when used in association with Veritas Alta Archiving.

Mitigation  

There are no further mitigation steps required for Veritas Alta Archiving.
