CVE-2015-1427 is a remote code execution vulnerability in the Groovy scripting engine used by Elasticsearch before 1.3.8 and in 1.4.x before 1.4.3. The flaw allows a crafted Groovy script to bypass the intended sandbox restrictions and reach dangerous Java functionality, including indirect access to process-execution primitives through reflection. Once the sandbox is evaded, attacker-supplied script code can execute arbitrary shell commands on the host running Elasticsearch. The issue affects exposed Elasticsearch instances where Groovy scripting is available and results in full compromise of the affected service context.

This repository provides a proof-of-concept exploit for CVE-2015-1427, a remote code execution vulnerability in Elasticsearch versions 1.4.0 to 1.4.2. The repository includes a Dockerfile to set up a vulnerable Elasticsearch environment, a main.sh script to initialize the service and add sample data, and an exploit.sh script that performs the actual exploit. The exploit works by sending a specially crafted Groovy script via the Elasticsearch REST API (typically on port 9200), which bypasses the Groovy sandbox and executes arbitrary system commands (demonstrated with 'whoami'). The exploit does not require authentication and targets the default REST API endpoint. The repository is structured for easy testing and demonstration of the vulnerability, making it suitable for educational and research purposes.
