How to Fix CVE-2023-6019

To remediate this vulnerability, upgrade all affected Ray dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ray fixed: 2.8.1 
pip install ray>=2.8.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show ray

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-6019, inspect your installed packages using pip:

pip show ray

Analyze the terminal output to locate any version of Ray in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.1), your application is affected.

Note: The pip show ray command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Ray, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A command injection exists in Ray's cpu_profile URL parameter allowing attackers to execute os commands on the system running the ray dashboard remotely without authentication.
