Unauthenticated RCE in Anyscale Ray Job Submission API
CVE-2023-48022 affects Anyscale Ray 2.6.3 and 2.8.0 and allows remote attackers to execute arbitrary code through Ray’s Job Submission API exposed by the Ray dashboard, typically at /api/jobs/ on port 8265. The issue is described in the provided content as a missing authentication flaw: if a Ray dashboard is reachable, an attacker can submit jobs to the unauthenticated Jobs API and cause attacker-controlled Bash or Python payloads to run on the cluster. Reporting around ShadowRay and ShadowRay 2.0 indicates the flaw has been exploited in the wild to launch multi-stage payloads, abuse Ray orchestration features to execute across cluster nodes, and pivot from exposed head nodes to additional internal nodes. The vendor position noted in the content is that Ray is intended for strictly controlled network environments rather than direct Internet exposure.

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.
