Solved: Updation of Log4J jar file in Elasticsearch

osadmin · ‎22 Dec 2021

Has the following update been made available, if no when to expect?

Please note that the Dynatrace Managed versions listed below still include the vulnerable Log4j library file (/opt/dynatrace-managed/elasticsearch/lib/log4j-core-2.11.1.jar) due to the usage of Elasticsearch. Dynatrace has applied the recommended mitigation measures of removing the org/apache/logging/log4j/core/lookup/JndiLookup.class from the Log4j library. This fully mitigates CVE-2021-44228 and CVE-2021-45046.

An upgrade of Elasticsearch which uses an updated Log4j library is planned.
