Should I be worried?
Our security team has just wrapped up a thorough analysis of our own systems. We have not identified any services, products, or applications that are at risk. However, we will continue to monitor the vulnerability as details are unfolding. cPanel also had this issue fixed if you had Solr plugin installed (auto-update would have fixed that issue a couple of days ago and DirectAdmin does not use log4j so if you have any managed server with us or have auto-update on cPanel (by default) issue does not apply to you.
