Unauthenticated RCE in Anyscale Ray Job Submission API
CVE-2023-48022 affects Anyscale Ray 2.6.3 and 2.8.0 and stems from missing authentication on the Ray dashboard/job submission interface. When the Ray dashboard API is exposed, a remote attacker can submit jobs through the unauthenticated Jobs API (commonly referenced as /api/jobs/ on the dashboard, default dashboard port 8265) and cause arbitrary code to execute on the Ray cluster. Reporting and incident writeups describe attackers abusing the exposed dashboard API to run multi-stage Bash and Python payloads, leveraging Ray orchestration features to execute across cluster nodes and pivot to additional internal systems. The vendor position noted in the source material is that Ray is intended only for strictly controlled network environments; later versions reportedly offer optional token authentication, but the issue is described in the provided content as historically unpatched for the affected versions.

This repository provides a weaponized exploit for CVE-2023-48022, a remote command execution vulnerability in the Ray framework (version 2.8.0). The exploit targets Ray's job submission API, which by default is unauthenticated and allows remote attackers to submit arbitrary jobs for execution. The repository contains two main exploit files: a Python script (exploit.py) for direct exploitation and a Metasploit module (ray_job_rce.rb) for integration with the Metasploit framework. The Python script allows users to specify a target Ray cluster and a command to execute, submitting the job via the Ray JobSubmissionClient. The Metasploit module automates exploitation, supporting both custom command execution and reverse shell payloads, and targets the '/api/jobs/' and '/api/job_agent/jobs/' endpoints. The README provides detailed usage instructions for both approaches. The exploit is operational and weaponized, enabling remote, unauthenticated code execution on vulnerable Ray clusters accessible over the network.
