All these protections are configured by an administrator. GitHub has evolved significantly since its inception and continues to add features, products, and tools for code management and shipment. If there is a protection, we can try to remove it specifically for this branch and perform the secrets extraction phase normally. Since the base branch is considered trusted, workflows triggered by these events will always run, regardless of approval settings. Not able to push on git - Write access to repository not granted.

Therefore, a full review of all tokens and user permissions should be performed to only give access to resources that are needed by applying the principle of least privilege. In fact, the YAML file instructs the pipeline agent to check out this repository. All GitHub docs are open source. This article aims at describing how to exfiltrate secrets that are supposed to be securely stored inside CI/CD systems. For managed repositories and organizations, the maximum retention period cannot exceed the limit set by the managing organization or enterprise. For obvious reasons, a user cannot approve their own pull request, meaning that a requirement of even one approval, forces another organization member to approve the merge request in the codebase. privacy statement. Kudos to GitHub for fixing this security flaw. You can find the URL of the local repository by opening the command line and typing git remote -v: As this is a non-standard OIDC configuration, we need to provide GitHub Actions with the format of the OIDC tokens to generate when running on the1yGUFNkFUT8VmEfjztRNjgrfH3AgzV/test_oidc2 repository. Connect and share knowledge within a single location that is structured and easy to search. So does a compromise of a single user account mean the attacker can push code down the pipeline without restrictions? But it says the above error. For more information, see "Removing workflow artifacts.". Such a service connection can be used in standard pipelines for authentication, for example with the AzureCLI task. Andra, if this is working for you please close the issue. To do so, service connections are used. but unfortunately, no. GitHub Actions is a CI/CD platform allowing users to automate their build, test and deployment pipeline. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

Generate the pipeline YAML file based on secrets to be extracted and write it to the root directory. This could run TruffleHog or Gitleaks on any new commits pushed to a remote branch and send email alerts to security teams if sensitive information leaks were to be detected. You can also define a custom retention period for a specific artifact created by a workflow. 3 Jonno_FTW 7 mo. Have a question about this project? However, we have demonstrated that these mitigations can be bypassed with administrator access to a project or repository. For more information, see "About remote repositories.". On the mitigation side, we have already seen it is possible to enable multiple protections on GitHub to prevent access to specific branches and secrets. There are two possible protections: wait timer and required reviewers. rev2023.3.1.43269. You can find the URL of the local repository by opening the command line and However, certain hardening settings can provide more granular control over access to repositories and thus to GitHub Actions secrets (see the, we need to provide GitHub Actions with the format of the OIDC tokens to generate when running on the, For example, it is possible to ask it to include the.

GitHub Actions now lets you control the permissions granted to the GITHUB_TOKEN secret. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. To use these secrets in a pipeline, a user must actually be able to modify an existing one that already has access to the targeted secrets, or they must be able to create a new one and give it the correct permissions. Anyone with write access to a repository can modify the permissions granted to the GITHUB_TOKEN, adding or removing access as required, by editing the permissions key in the workflow file. Therefore, they can only be consumed from a task within a pipeline. Why is the article "the" used in "He invented THE slide rule"? But if this task is able to use those credentials, this means it is possible to exfiltrate them6. Actions and reusable workflows in your private repositories can be shared with other private repositories owned by the same user or organization. Note: The Allow specified actions and reusable workflows option is only available in public repositories with the GitHub Free, GitHub Pro, GitHub Free for organizations, or GitHub Team plan. Why do we kill some animals but not others? The wait timer option sets an amount of time to wait before allowing deployments to proceed.

Note that references to the malicious commits could still be found in the repository events and these commits may still be accessible directly via their SHA-1 hashes in cached views on GitHub. For example, an application deployment can be triggered after a developer pushes a new version of the code to a repository. I see you mentioned you have provided the access, I just tried all three ways they are working fine for me. Git clone / pull continually freezing at "Store key in cache? If I try to create a new PAT and try to create it for specific repos, I can't see this new repo in the list of my repos! Contrary to secret variables in variable groups, there is no need to obfuscate the output of the script execution, since Azure Pipelines do not seem to detect secure files extraction. Here is a diagram from the kubernetes community that provides a clear depiction of the git workflow. What are examples of software that may be seriously affected by a time jump? After the secrets extraction phase, the branch is deleted. Navigate to cPanel's Git Version Control interface ( cPanel Home Files Git Version Control ).

This way, a GitHub Actions workflow running on the 1yGUFNkFUT8VmEfjztRNjgrfH3AgzV/test_oidc2 repository, on a test-branch branch and in the context of the TEST_ENV environment will be able to get access tokens as the CICD-SP-OIDC-GitHub Azure application. I don't know why GitHub do it this way - but note that it's entirely up to GitHub; Git itself doesn't take part in the authentication and access restrictions. The token has write permissions to a number of API endpoints except in the case of pull requests from forks which are always . If you try to clone git@github.com:user/repo.git, but the repository is really named User/Repo you will receive this error.

When possible, enabling commit signature verification is also a good protection, since it would prevent a non-administrator attacker having only compromised a token from pushing files to trigger a malicious workflow. Our research has exposed a flaw that leverages GitHub Actions to bypass protected branch restrictions reliant on the multiple reviews control. There are a few common errors when using HTTPS with Git. Make sure that you have access to the repository in one of these ways: The owner of the repository A collaborator on the repository A member of a team that has access to the repository (if the repository belongs to an organization) Check your SSH access In rare circumstances, you may not have the proper SSH access to a repository.

In either case it's likely trying to write to the repository either as a different configured user or no configured user at all. We will use this example to explain how this can be configured but also abused. ). There's a link in there about changing to the Git Credential Manager if you prefer something like that. In November 2021 our team took part in the ZDI Pwn2Own Austin 2021 competition [1] with multiple entries. That token should start with ghp_: it should then authenticate you properly, allowing you to clone the repository, and push back to it. Storing long-lived secrets in CI/CD systems presents multiple issues. We recommend you to use this new setting to disallow malicious actors from bypassing branch protection rules by approving their own pull requests. Ah, yes, that was the underlying reason. The repository you're trying to fetch must exist on GitHub.com, and the URL is case-sensitive. I use my User access token. If indeed the Personal access token above is authorized to access that repo you should now be able to do all functions from before such as cloning, pushing and pulling. Has Microsoft lowered its Windows 11 eligibility criteria? Note that a token can have theadmin:org scope for example, but if the associated user is not an organization administrator, the scope will be useless. Would the reflected sun's radiation melt ice in LEO? So if your organization uses GitHub, but doesnt use GitHub Actions for CI, you obviously have no reason to be concerned about this flaw, right? This begs the question, if you are an organization using GitHub, but havent yet gotten started with GitHub Actions, should you be worried about GitHub Actions attack surface, even if you never installed or used it in your organization? For instance, the Azure Resource Manager type allows the pipeline to log in to an Azure tenant as a service principal. A pipeline is bounded to an Azure DevOps repository, but a repository can have multiple pipelines, each of which can perform a different set of tasks. git remote set-url origin https://
