GitHub Vulnerability Alerts

CVE-2023-52137

Summary

The tj-actions/verify-changed-files action allows for command injection in changed filenames, allowing an attacker to execute arbitrary code and potentially leak secrets.

Details

The verify-changed-files workflow returns the list of files changed within a workflow execution.

This could potentially allow filenames that contain special characters such as ; and ` (backtick) which can be used by an attacker to take over the GitHub Runner if the output value is used in a raw fashion (thus being directly replaced before execution) inside a run block. By running custom commands an attacker may be able to steal secrets such as GITHUB_TOKEN if triggered on other events than pull_request. For example on push.

Proof of Concept

Submit a pull request to the repository with a new file injecting a command. For example $(whoami).txt would be a valid filename.
Upon approval of the workflow (triggered by the pull request), the action will get executed and the malicious pull request filename will flow into the List all changed files tracked and untracked files step.

- name: List all changed files tracked and untracked files
  run: |
    echo "Changed files: $"

Example output:


##[group]Run echo "Changed files: $(whoami).txt"
  echo "Changed files: $(whoami).txt"[0m
shell: /usr/bin/bash -e {0}

##[endgroup]
Changed files: runner.txt

Impact

This issue may lead to arbitrary command execution in the GitHub Runner.

Resolution

A new safe_output input would be enabled by default and return filename paths escaping special characters like ;, ` (backtick), $, (), etc for bash environments.
A safe recommendation of using environment variables to store unsafe outputs.

- name: List all changed files tracked and untracked files
  env:
     CHANGED_FILES: $
  run: |
    echo "Changed files: $CHANGED_FILES"
