Trufflehog:ignore - Buildkite - Gh Action

by ADMIN 42 views

Introduction

TruffleHog is a powerful tool for detecting secrets in code repositories. However, when using the trufflehog:ignore feature in conjunction with the Buildkite detector, unexpected behavior can occur. In this article, we will delve into the issue and explore the necessary steps to reproduce and resolve it.

TruffleHog Version

The current version of TruffleHog being used is 3.88.15, as indicated by the gh action output.

Status: Downloaded newer image for ghcr.io/trufflesecurity/trufflehog:latest
gh action: trufflehog 3.88.15

Trace Output

For a more detailed understanding of the issue, please refer to the trace output provided in the GitHub Gist.

Expected Behavior

When using the trufflehog:ignore feature, it is expected that the specified file or line will be skipped, and the TruffleHog scan will continue without errors.

Actual Behavior

However, in this case, the TruffleHog scan fails due to an "unverified secret" error, even when the trufflehog:ignore feature is used. This is because the PLUGIN_TOOL environment variable is being detected as a secret, despite being a Git commit SHA used to checkout a specific version of a plugin.

Example Code

  - foo-bar:
      valuebool: true
      fileDefinitio: .pathtoFile.yml
      env:
        - PLUGIN_TOOL: e5637ca1ed34a227eba86ae30761010f308b2d1b

Steps to Reproduce

To reproduce this issue, follow these steps:

  1. Setup a TruffleHog: Create a new TruffleHog instance and configure it to use the trufflehog:ignore feature.
  2. Configure the Buildkite detector: Set up the Buildkite detector to exclude the PLUGIN_TOOL environment variable.
  3. Run the TruffleHog scan: Run the TruffleHog scan with the --exclude-detectors="Buildkite" argument.

Additional Context

To resolve this issue, it is necessary to pass the --exclude-detectors="Buildkite" argument to the TruffleHog scan. This can be achieved by modifying the extra_args field in the workflow configuration.

name: trufflehog secret scan
on:
  workflow_dispatch:
  pull_request:
    branches: [ main ]

jobs:
  TruffleHog:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
        with:
          fetch-depth: 0
      
      - name: TruffleHog secret scan
        uses: trufflesecurity/trufflehog@main
        with:
          path: ./
          extra_args: --log-level=5 --exclude-detectors="Buildkite"
        continue-on-error: false

Introduction

In our previous article, we explored the issue with the trufflehog:ignore feature and the Buildkite detector in TruffleHog. In this Q&A article, we will answer some of the most frequently asked questions related to this issue.

Q: What is the trufflehog:ignore feature?

A: The trufflehog:ignore feature is a way to exclude specific files or lines from the TruffleHog scan. This can be useful for ignoring false positives or excluding sensitive information.

Q: Why is the Buildkite detector detecting the PLUGIN_TOOL environment variable as a secret?

A: The Buildkite detector is detecting the PLUGIN_TOOL environment variable as a secret because it is a Git commit SHA used to checkout a specific version of a plugin. However, the TruffleHog scan is treating it as a secret due to a misconfiguration.

Q: How can I resolve this issue?

A: To resolve this issue, you need to pass the --exclude-detectors="Buildkite" argument to the TruffleHog scan. This can be achieved by modifying the extra_args field in the workflow configuration.

Q: What is the extra_args field in the workflow configuration?

A: The extra_args field in the workflow configuration is used to pass additional arguments to the TruffleHog scan. In this case, we are using it to exclude the Buildkite detector.

Q: How do I modify the extra_args field in the workflow configuration?

A: To modify the extra_args field in the workflow configuration, you need to update the trufflehog step in your workflow file. Here is an example of how to do it:

name: trufflehog secret scan
on:
  workflow_dispatch:
  pull_request:
    branches: [ main ]

jobs:
  TruffleHog:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
        with:
          fetch-depth: 0
      
      - name: TruffleHog secret scan
        uses: trufflesecurity/trufflehog@main
        with:
          path: ./
          extra_args: --log-level=5 --exclude-detectors="Buildkite"
        continue-on-error: false

Q: What is the continue-on-error field in the workflow configuration?

A: The continue-on-error field in the workflow configuration is used to determine whether the workflow should continue running even if an error occurs. In this case, we are setting it to false to ensure that the workflow fails if the TruffleHog scan encounters an error.

Q: How do I troubleshoot this issue?

A: To troubleshoot this issue, you can try the following:

  • Check the TruffleHog logs for any errors or warnings.
  • Verify that the trufflehog:ignore feature is correctly configured.
  • Ensure that the Buildkite detector is properly configured.
  • Try running the TruffleHog scan with the --log-level=5 argument to enable debug logging.

By following these steps and troubleshooting tips, you should be able to resolve the issue with the trufflehog:ignore feature and the Buildkite detector in TruffleHog.
