The security hole Log4j is current and affects only Java applications. For Firestorm customers there is no danger, because our servers do not use Java applications. For this reason we can say that our products are not affected by this vulnerability. This includes our webhosting packages as well as our servers.<\/p>\n

 <\/p>\n

With own Rootservern is however caution advised<\/p>\n

If you run your own server and use Java applications, then you may be affected by the vulnerability. There are several Java applications that use Log4j. If they are used, then you need to update the application as soon as possible to close the vulnerability as soon as possible.<\/p>\n
