Welcome to Infinity, [Bassxn2]! :) The log4j is a computer security issue, and 0-day-ish issue, and it's super-widespread, because Log4j is very popular library used in all kind of software.

It's good it's easy to fix:

  • Java 8's Log4j to >=2.17.0
  • Java 7's Log4j to >=2.12.3
  • Java 6's Log4j to >=2.3.1
  • OR remove zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class

Lookup for traces of intrusion:

Take a note, that this issue is very circumstantial time-sensitive, it is not a long-term global challenge. [marked-for-expiry]
