Elasticsearch&Logstash Log4j Vulnerabilities


We have log4j vulnerabilities for Elasticsearch and Logstash in the following paths:

Path : /usr/share/Elasticsearch/lib/log4j-core-2.11.1.jar
Path : /usr/share/logstash/logstash-core/lib/jars/log4j-core-2.14.0.jar

Is there a workaround to fix the vulnerabilities? Otherwise, Is the only solution to upgrade the application version?

Logstash and Elasticsearch version: 7.13

Could you help me to solve the problem?


Welcome to our community! :smiley:

If you are referring to the log4shell vulnerabilities then please see 7-0-0-7-16-0-log4j-cve-2021-44228-cve-2021-45046-remediation/292343

I think Mark meant to link to this thread.

Thanks for your updates. The link you provided for me is about Logstash. Is there a solution for Elasticsearch too?


Of course. The overall elastic view of the vulnerability can be found in this blog post. I do not run Elasticsearch, but I would start here. There is a ton of detail about versions and configuration variations. If an upgrade is viable then I would certainly recommend it.

Yeah, that was a copy paste error!
