Solr Log4js-1.2.17.jar Vulnerability

Hi Jayraj, thanks for answering the query I downloaded the latest version repository and I see there a lot of jar files there but there is no jar with the name of existing jar file, so could you please confirm me the correct jar file name which I need to replace in solr and is it required to rename that jar file  

To update the Solr Log4js version to mitigate the vulnerability, follow these steps:

1. Download the latest Log4js version 2.23.0 from the official Apache Log4j website or repository.
2. Replace the existing log4j-1.2.17.jar file located at Solr\721\solr-7.2.1\server\lib\ext\ with the new Log4js version.
3. Restart the Solr server to apply the changes and ensure proper functionality.
4. Test the Solr application thoroughly to verify that the update has been successful and that the vulnerability has been addressed.
