Loading vulnerability…
CVE-2015-5531 is a directory traversal vulnerability in Elasticsearch versions before 1.6.1 affecting Snapshot API handling. Crafted snapshot-related input containing encoded traversal sequences can escape the intended snapshot repository location and cause Elasticsearch to read arbitrary files accessible to the Elasticsearch service account. The issue is particularly relevant where a snapshot repository path is configured and snapshot functionality is exposed to an attacker.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/scanner/http/elasticsearch_traversal.rb) that exploits a directory traversal vulnerability (CVE-2015-5531) in ElasticSearch's Snapshot API. The module allows an attacker to read arbitrary files from the server's filesystem with the privileges of the JVM process running ElasticSearch. The exploit works by creating malicious snapshot repositories and then crafting a GET request with directory traversal sequences to access files outside the intended directory. The module is operational, providing file exfiltration capabilities, and saves the retrieved file as loot in Metasploit. The attack is performed over the network (HTTP, default port 9200), and the main endpoints targeted are the Snapshot API URIs. The code is written in Ruby and is intended to be run within the Metasploit framework.
