Exploiting Elasticsearch

Sometimes, while doing a pentest, we may also come across some of the services running on various port numbers; one such service is what we will look at in this recipe. Elasticsearch is a Java-based, open source search enterprise engine. It can be used to search any kind of document in real-time.

In 2015, an RCE exploit came for Elasticsearch, which allowed hackers to bypass the sandbox and execute remote commands. Let's see how.

How to do it...

  1. The default port is 9200. Start the Metasploit console:
  1. Search for the Elasticsearch exploit using the following command:
 search elasticsearch

The output of the preceding command is shown in the following screenshot...
