testfiles/addaction/output/2jobs.yml

• [High]Use of default runner in a public pipeline
  The pipeline is using the default runner which provides unrestricted internet access. This can result in security vulnerabilities, such as downloading and executing malicious code. Use a self-hosted runner with restricted internet access, or configure a custom Docker image that provides only the necessary dependencies and tools for the pipeline to run.
• [High]Using a version of a third-party action instead of a commit ID
  Third-party actions can contain vulnerabilities or malicious code. Using a specific commit ID ensures that the exact code is being executed and that any changes or vulnerabilities introduced in later versions are not affecting the pipeline. Update the pipeline to use a specific commit ID instead of a version tag to reference third-party actions.
• [High]No validation of the egress-policy parameter
  The egress-policy parameter specifies the access control policy for outbound network connections. If the parameter is not validated, it can be manipulated to grant unrestricted internet access or to bypass security policies. Validate the egress-policy parameter to ensure it contains only the allowed values, such as 'allow', 'audit', or 'deny'.
• [Medium]No version specified for the third-party action
  Using a version tag without a specific version number can lead to unexpected behavior or vulnerabilities if the third-party action is updated. Specifying a version number ensures that the exact code is being executed. Update the pipeline to specify a version number for the third-party action.
• [Medium]No use of the 'pull_request' event for the pipeline triggers
  GitHub Actions can detect pull requests and trigger pipelines accordingly. Not using this event can lead to missed vulnerabilities or security concerns that can be detected during the code review process. Update the pipeline triggers to include the 'pull_request' event.
• [Low]Lack of explicit 'runs-on' parameter
  Without an explicit 'runs-on' parameter, the pipeline might behave differently depending on the runner environment. This can lead to unexpected behavior or vulnerabilities. Update the pipeline steps to include an explicit 'runs-on' parameter.

testfiles/secureworkflow/output/allscenarios.yml

• [High]Avoid using outdated dependencies
  The Git patch includes a dependency step-security/harden-runner@ebacdc22ef6c2cfb85ee5ded8f2e640f4c776dd5 that is not up-to-date. Outdated dependencies can introduce security vulnerabilities into your software. Update the dependency to its latest stable release by checking for updated versions in the official repository and then adding the updated references to the project's dependencies.
• [High]Avoid using hardcoded values
  The step name Harden the runner (Audit all outbound calls) should not be hardcoded as this will prevent its reuse in other contexts. Create a variable to hold the step name and reference it where necessary; this will make it easier to reuse the step elsewhere.
• [High]Follow the principle of least privilege
  By setting the egress-policy as audit, the code allows all outbound network calls without any restrictions. This is a security risk because it violates the principle of least privilege. Define specific policies that restrict outbound network calls to specific hosts and ports. This will limit access to only the required resources.
• [Medium]Reduce the attack surface
  The code does not require authentication or authorization for outbound network calls, thus exposing any sensitive information transmitted over the network to attackers. Implement authentication and authorization checks for outbound network calls. This ensures that only authorized users are allowed to initiate network communications.
• [Medium]Avoid using outdated packages
  The code uses packages that are either outdated or unmaintained, making it susceptible to security vulnerabilities. Update the packages to their latest stable releases or replace the packages with alternatives that are updated and maintained.
• [Low]Follow naming conventions
  The step name Harden the runner (Audit all outbound calls) does not follow the naming conventions, making it harder for developers to understand the purpose of the code. Update the name to comply with the naming conventions that are defined in the project's standards and are easily recognizable to the team.
• [Low]Implement error handling
  The code does not implement error handling, which means that unexpected errors can occur during the runtime of the program. Implement error handling to capture any unexpected errors and handle them appropriately. This will ensure that the program runs correctly and doesn't crash.

testfiles/secureworkflow/output/missingaction.yml

• [High]Avoid using specific Git revision numbers in workflow files
  Using specific Git revision numbers in workflow files can lead to issues such as incorrect or unexpected behavior when the referenced branch or commit no longer exists or has been modified. It is recommended to use branch names or tags instead. Replace the Git revision number in the 'uses' field with a branch name or tag.
• [High]Avoid using outdated or vulnerable actions
  Using outdated or vulnerable actions puts the workflow and the overall system at risk. It is recommended to use the latest versions of the actions or their equivalents, and to regularly check for potential vulnerabilities. Update the action used in the 'uses' field to the latest version available or an equivalent.

testfiles/secureworkflow/output/noperms.yml

• [High]Use the latest version of the step-security/harden-runner action
  The current action version (v2.0.0) may have known security vulnerabilities. Always use the latest version of a security-related package to ensure that you are protected from the latest threats. Update the action to the latest version. For example:
• name: Harden the runner (Audit all outbound calls)
  uses: step-security/[email protected]
  with:
  egress-policy: audit
• [High]Inject secrets as environment variables rather than arguments
  Using command line arguments to pass secrets can expose them to shell history or process listing. Injecting secrets as environment variables minimizes the chance of exposure. Pass the secrets as environment variables instead of command line arguments. For example:
• name: Harden the runner (Audit all outbound calls)
  uses: step-security/harden-runner
  with:
  egress-policy: audit
  env:
  SECRET_KEY: ${{ secrets.SECRET_KEY }}
• [High]Add a checkout step to the job
  The job appears to be missing a checkout step to fetch the source code before running the linting process. Without checkout, the linting process may not have access to the latest code changes. Add a checkout step to fetch the source code. For example:
• name: Checkout
  uses: actions/checkout@v2
• name: Harden the runner (Audit all outbound calls)
  uses: step-security/harden-runner
  with:
  egress-policy: audit
• [Medium]Limit the scope of secrets
  The current use of secrets in the job appears to be global, which could potentially expose secrets to other jobs. Minimize the potential for exposure by setting secrets only on a need-to-know basis, ideally at the job level or lower. Set secrets only where needed, preferably at the job level. For example:
  jobs:
  env:
  MY_SECRET_1: ${{ secrets.MY_SECRET_1 }}
  build:
  env:
  MY_SECRET_2: ${{ secrets.MY_SECRET_2 }}
• [Medium]Restrict the permissions of secrets
  The secrets used in the job may have unnecessarily broad access to resources and APIs. Restrict the permissions granted to the secret to only those required by the job. Check the permissions of secrets used in the job and restrict them to only what is required.
• [Medium]Use specific actions versions
  Using a specific action version ensures that the job is always using the same version of the action. Specify the version of the action to use. For example:
• name: Harden the runner (Audit all outbound calls)
  uses: step-security/[email protected]
  with:
  egress-policy: audit
• [Low]Specify the Ubuntu version for the runner
  When running a job on a self-hosted runner, it is recommended to set the version of the OS to ensure consistency and compatibility. Set the version of Ubuntu for the self-hosted runner. For example:
  runs-on: self-hosted [Ubuntu 20.04]

remediation/workflow/hardenrunner/addaction.go

• [High]Don't use Hardcoded secrets
  The use of hardcoded secrets in the code could compromise data security. Static analysis tools like SonarQube can identify hardcoded secrets and provide recommendations for fixing the potential security vulnerability. Use environment variables to store secrets and don't allow hardcoded secrets in code. The secrets can be loaded from environment variables when the application or script starts.
• [High]Use HTTPS instead of HTTP
  The use of HTTP instead of HTTPS can lead to man-in-the-middle attacks or other similar types of attacks. The National Institute of Standards and Technology (NIST) recommends using secure protocols for transmission of sensitive data. Use HTTPS to encrypt network traffic between the client and server. This can be achieved by obtaining an SSL/TLS certificate from a trusted provider and configuring the server to use it.
• [Medium]Sanitize inputs
  Unsanitized inputs can lead to code injection attacks and other types of security vulnerabilities. Validate and sanitize all inputs to the application or script. Use input validation libraries and sanitize user inputs by removing special characters and enforcing input length limits.
• [Medium]Implement Access Controls
  Access controls are critical to ensure that only authorized users are able to access and modify data or system resources. Implement access controls to restrict access to sensitive data and system resources. Use authentication and authorization mechanisms to enforce access controls.
• [Low]Avoid using weak cryptographical methods
  Weak encryption or hashing algorithms can lead to easy cracking of sensitive data and secrets. Use strong encryption and hashing algorithms such as Advanced Encryption Standard (AES) and Secure Hash Algorithm (SHA) to secure sensitive data and secrets.
• [Low]Disable Directory Listing
  Allowing directory listing may reveal sensitive information to attackers without any authentication. Disable directory listing in the application or server configuration file to prevent unauthorized access to sensitive information.

testfiles/addaction/output/alreadypresent.yml

• [High]Avoid using the latest tag for Docker images
  The 'latest' tag for Docker images should be avoided as it can lead to unexpected changes and vulnerabilities in the image being used. Change the Docker image tag from 'latest' to a specific version number.
• [Medium]Specify the version of the Ubuntu image
  When using a Docker image, it is important to specify the version of the operating system being used to ensure consistency and security. Specify the appropriate version of the Ubuntu operating system in the Docker image tag.
• [Medium]Use a validated base image
  Using a validated base image can help ensure that the image being used is secure and does not contain known vulnerabilities. Use an image that has been validated by a trusted source such as Docker Hub or a company's internal registry.
• [Low]Provide more descriptive names for steps
  Providing descriptive names for each step in a workflow can help make it more readable and maintainable. Rename the step to something more descriptive such as 'Audit outbound calls' instead of 'Harden runner'.

testfiles/addworkflow/expected-scorecards.yml

• [High]Update to latest version of dependency
  The ossf/scorecard-action dependency is outdated. The latest version should be used for security purposes. Update the ossf/scorecard-action dependency to version v2.4.0.
• [Medium]Set persist-credentials to true
  Setting persist-credentials to true ensures that secrets and other secure information entered during the workflow run is not lost and can be reused later if needed. Set persist-credentials to true in the checkout step of the workflow.

testfiles/secureworkflow/output/nopin.yml

• [High]Do not rely solely on third party security tools, perform manual code reviews as well
  The use of a third party tool to harden the runner is not sufficient. It is important to also perform manual code reviews to ensure that the code is secure. According to OWASP ASVS V4.1 (V2.3): "Verify that all code is reviewed by one or more individuals who are knowledgeable in code review techniques for the technology in use, and that all identified issues are addressed before release". Perform manual code reviews in addition to using third party security tools.
• [Medium]Provide a reason for the 'audit' egress policy
  In the code, an egress policy of 'audit' is applied without providing a reason for this policy. According to NIST SP 800-53 (Rev. 4, CM-7): "The organization develops and documents a purpose for the information system". It is important to provide a reason for the egress policy to ensure that it is appropriate for the specific use case. Provide a reason for using the 'audit' egress policy.
• [Low]Use descriptive names for steps in the job
  The name of the step 'Harden the runner (Audit all outbound calls)' should be more descriptive and informative. According to OWASP ASVS V4.1 (V10.9): "Use descriptive function and variable names that unambiguously convey their purpose, and how and where they are used". Use a more descriptive step name such as 'Apply outbound egress audit policy to runner'.

workflow-templates/scorecards.yml

• [High]Update dependency versions regularly to get the latest patches
  The commit updates the dependency version of ossf/scorecard-action. Regularly updating dependencies ensures that any security vulnerabilities or bugs are fixed and that the dependencies are compatible with other packages. Regularly check for updates to dependencies and update them to the latest version. Use dependency management tools like npm or yarn to automate this process.
• [Low]State the exact version of dependency to ensure precise matching
  The uses field in line 44 does not specify the exact version of the ossf/scorecard-action dependency, which could result in unexpected changes in the future. Stating the exact version ensures precise matching of dependencies. Specify a fixed, exact version number for the dependency in the uses field to ensure exact matching, e.g. uses: ossf/[email protected].

testfiles/addaction/output/action-issues.yml

• [High]Set explicit version of the action to use
  The current version being used is 'v2'. If there is a newer version available, then upgrading could provide additional security features, bug fixes and improvements. Update the action to use an explicit version by replacing 'v2' with the desired version in the 'uses' field. Example: 'uses: step-security/harden-runner@v3'
• [Medium]Check compatibility of chosen action version with current OS configuration
  The 'harden-runner' action might not be compatible with the current OS configuration. Check for the latest release notes that the chosen action version is compatible with the OS version. Verify that the dependencies of the action are compatible with the OS configuration.
• [Medium]Ensure necessary and least privileges are given to the action
  The 'harden-runner' action could potentially require additional privileges to achieve the desired outcome. Review the documentation of the action to understand and fine-tune the necessary privileges required for the action. Provide only those permissions and privileges that are necessary for the runner.
• [Low]Add description to action
  There is no description provided to the 'harden-runner' action. Adding a description will help any other engineer or developer to understand the purpose of the action. Add a description to the 'harden-runner' action to explain its purpose, its impact and how it relates to other steps in the workflow. Example: 'This action audits all outbound calls for increased security during pipeline runs.'
