Workarounds and Mitigations

IBM strongly recommends addressing the vulnerability now by executing these manual steps, for Log4j in Elasticsearch and Logstash.

IBM Spectrum Archive Enterprise Edition includes three dependent software which include the version of Apache Log4j with the vulnerability described in CVE-2021-44228.  They are

  • HSM Component in IBM Spectrum Archive Enterprise Edition Log4j 2.13.3
  • Elasticsearch 5.6.8  in IBM Spectrum Archive Enterprise Edition Log4j 2.9.1
  • Logstash 5.6.8 in IBM Spectrum Archive Enterprise Edition Log4j 2.6.2 

HSM component is always installed by the default installation procedure of IBM Spectrum Archive Enterprise Edition, and Elasticsearch and Logstash RPMs are manually installed when the dashboard function is needed.


Fix for Log4j shipped with HSM component

Upgrade to the version described in Remediation/Fixes section.


Mitigation for Log4j bundled in Elasticsearch and Logstash

Logstash is typically installed under /usr/share/logstash directory on all IBM Spectrum Archive nodes when the dashboard function is used, and Elasticsearch is installed under /usr/share/elasticsearch directory on external monitoring server.  Per the Apache Log4j security vulnerability advisory, find the Log4j jar files under those installation directories, and remove the JndiLookup class from the jar files by: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class See the security announcements and detailed instructions from Elastic for removing JndiLookup from relevant JAR files​.
