Consider the possible ways for a string to be injected into any of the following:

  Apache Solr
  Apache Druid
  Apache Flink
  ElasticSearch
  Flume
  Apache Dubbo
  Logstash
  Kafka
If you've got any of them, they're likely exploitable too.

That list comes from: https://unit42.paloaltonetworks.com/apache-log4j-vulnerabili...

The attack surface is quite a bit larger than many realize. I recently had a conversation with a person who wasn't at a Java shop so wasn't worried... until he said "oh, wait, ElasticSearch is vulnerable too?"

You'll even see it in things like the connector between CouchBase and ElasticSearch ( https://forums.couchbase.com/t/ann-elasticsearch-connector-4... ).
