Upgrading log4j in 7.2.1 is probably not an easy task. It would be much easier to upgrade to at least Solr 7.4.0, which was the first version of Solr to use log4j2. Then you could simply replace the log4j2 jars in the Solr download with the newer version from log4j.
Alternately, you could reconfigure the logging system to log to another destination entirely, and not even use log4j. This is not difficult, but it requires some jar changing, and you would need to fiddle with the start script to provide a configuration to the alternate logging destination.
Thanks, Shawn
