Description

This module exploits a remote command execution (RCE) vulnerability in ElasticSearch, exploitable by default on ElasticSearch prior to 1.4.3. The bug is found in the REST API, which does not require authentication, where the search function allows groovy code execution and its sandbox can be bypassed using java.lang.Math.class.forName to reference arbitrary classes. It can be used to execute arbitrary Java code. This module has been tested successfully on ElasticSearch 1.4.2 on Ubuntu Server 12.04.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
