A port that includes a file called log4j-$version.jar with $version in the range 2.0.0-2.14.1 could be vulnerable. This file could also be ‘hidden’ inside a compressed archive, like a .war file (basically a zip file). I’m not sure how we could check all ports for this without installing all of them.

I said to look log4j-$version.jar earlier, but I should have said log4j-core-$version.jar.

In your list apache-solr8 and apache-geode contain vulnerable versions of Log4J 2.x.
