I am using/running ELK 7.13 version on my environment using docker compose along with Filebeat 7.14 and have enabled xpack security option.
I have restarted all three containers using docker compose and completed successfully.
I just wanted to know do I need to do anything to remediate the log4j vulnerability for my ELK stack.
For proper fix, you need to update
- Disable JNDI lookups via the
log4j2.formatMsgNoLookups system property #81622
- Patch log4j jar to remove the
JndiLookup class from the classpath #81629
Hello @FALEN ,
Thank you for your reply. Let me update my ELK stack to 7.16.1 version.
Will update once done.
May I know do we have updates on log4j 2.17.1 for elk stack?
Logstash v2.17.1 is mitigate against CVE-2021-44832 from the 28th of December. I've asked about it here: Log4j CVE-2021-44832 (released 28th dec) - is ES vulnerable? but thus far no conclusive answer.
I don't know about Logstash, but I do know no update containing log4j 2.17.1 has been released yet for Elasticsearch (it would be released in 7.16.3, but the latest as of writing is 7.16.2).
