Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/elasticsearch/indices_enum
msf auxiliary(indices_enum) > show options
... show and set options ...
msf auxiliary(indices_enum) > set RHOSTS ip-range
msf auxiliary(indices_enum) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(indices_enum) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(indices_enum) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(indices_enum) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Description
This module identifies a list of indices which an Elasticsearch NoSQL database has. This occurs over the REST API, which on community versions is an unauthenticated API. Customers who subscribe to a support plan can add authentication to this API restricting access.
Vulnerable Application
Install Elasticsearch on Kali Linux:
With this install, we'll install the free community edition of Elasticsearch, which does not require authentication to the API. However, this is unrealistic in a production environment which will often leverage a support contract to gain authentication, a reverse proxy to add basic authentication, and/or a host firewall to restrict access to this API.
The following instructions assume you are beginning with a fresh Kali installation as the root user.
useradd -M -r elasticsearch
su elasticsearch
cd /tmp
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.3.2.tar.gz
tar -xvf elasticsearch-6.3.2.tar.gz
cd elasticsearch-6.3.2/bin
./elasticsearch
- Open a new terminal
- In the new terminal,
curl -X PUT http://127.0.0.1:9200/msf_test
to create an index for validation purposes
Verification Steps
use auxiliary/scanner/elasticsearch/indices_enum
set RHOSTS [ips]
set RPORT [port]
run
Scenarios
Elasticsearch 6.3.2 on Kali Linux
msf > use auxiliary/scanner/elasticsearch/indices_enum
msf auxiliary(scanner/elasticsearch/indices_enum) > set RHOSTS 10.10.10.25
RHOSTS => 10.10.10.25
msf auxiliary(scanner/elasticsearch/indices_enum) > run
[+] ElasticSearch Indices found: msf_test
