remote write access to repository not granted github actions

The token has write permissions to a number of API endpoints except in the case of pull requests from forks which are always read. You can resolve it by setting origin URL with your personal access token. 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. For more information, see "Allowing select actions and reusable workflows to run.". There are two possible protections: wait timer and required reviewers. Is variance swap long volatility of volatility? Indeed, since the protection is removed, a new one is created by GitHub because the protections applying to our branch and the protections applying to the branch name pattern are not the same anymore: However, it is not possible to remove this rule via the REST API. You can configure this behavior for a repository using the procedure below. Push the modification, which triggers the GitHub workflow and runs it. They accepted it, wrote that itll be tracked internally until resolved, and approved to publish a write-up. If there is a protection, we can try to remove it specifically for this branch and perform the secrets extraction phase normally. You can disable GitHub Actions for a repository, or set a policy that configures which actions and reusable workflows can be used in the repository. Although workflows from forks do not have access to sensitive data such as secrets, they can be an annoyance for maintainers if they are modified for abusive purposes. Is there anything specific to do when creating repos inside an organization? This issue has grown ever since Git*Hub has brought token authentication into account. The same problem arises when rotating secrets on a regular basis. Setting the default to contents:read is sufficient for any workflows that simply need to clone and build. However, the traces of these secrets remain present in the commit history as long as it is not rewritten by a forced push. ", Git Not Allowing to push changes to remote Repo, Cannot push branch to git(remote: Write access to repository not granted. Actions generates a new token for each job and expires the token when a job completes. Collection of actionable measures across Prevention, Mitigation, Detection and assessment for coping w Cider Security has been acquired by Palo Alto Networks. First, we need to add federated credentials to an Azure application: We then specify that the credentials will be used in the context of a GitHub Actions workflow: The most important part lies in the configuration of the issuer and the subject identifier, which together define the trust relationship. Only for "classic" token. Storing long-lived secrets in CI/CD systems presents multiple issues. Monitoring deployment logs and run logs for unusual activity can be a good starting point. You can also define a custom retention period for a specific artifact created by a workflow. You can always download the latest version on the Git website. Checking the options that GIThub give when I push on clone repository. This setting allows granting the token with restricted permissions . In the future, support for other CI/CD systems, such as GitLab, Jenkins and Bitbucket, may be added. At least in my case, it helped, since all the answers in this article did not work for me. the following into the command line: If the repository belongs to an organization and you're using an SSH key generated by an OAuth App, OAuth App access may have been restricted by an organization owner. Not the answer you're looking for? You can choose a restricted set of permissions as the default, or apply permissive settings. If GitHub Actions is in use in the organization, you can do one of the following. For more information, see "Removing workflow artifacts.". For instance, if a user is deploying a lot of workflows on many repositories in a short amount of time and from a suspicious location, this might indicate malicious activity. Please use a personal access token instead.". So, what does a typical GitHub organization look like?It generally has: Practically, this means an attacker that hijacks a user account and wants to push code to a protected branch, can simply push their malicious code to a new remote branch, along with a workflow with the following content: Then, the attacker creates a pull request, with the intent to merge their malicious code to a protected branch. The same YAML file is generated but to specify an environment, the environment parameter is added. By clicking Sign up for GitHub, you agree to our terms of service and I have no idea how this setting got set differently on the repos as I haven't touched it. Under Fork pull request workflows from outside collaborators, select your option. A workflow in the GitHub terminology is a configurable and automated process that will run one or more jobs. GitHub Actions is a CI/CD platform allowing users to automate their build, test and deployment pipeline. By default, Nord Stream goes through all the environments but it is possible to specify a selection of them. The practice we are following from Red Hat is that users should fork, not clone repositories, and present their PRs from the fork against the appropriate branch within the main repository (main, develop, whatever). Visit your Git, go to your repository, click on Clone repository, there you'll see the option to generate credentials. Each token can only access specific repositories. Under your repository name, click Settings. A GitHub organization can include any number of members from several to hundreds or even thousands of members, with varying permissions. 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. If you try to clone git@github.com:user/repo.git, but the repository is really named User/Repo you will receive this error. 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. However mine were already set and I still have the error, select a project goto Settings > Actions > General , can find there "Workflow permissions". Then, the file path can be referenced in the pipeline as $(secretFile.secureFilePath). However, in order to integrate, deliver and deploy, these systems need credentials to seamlessly interact with other environments, like cloud ones. For more information, see Adding a new SSH key to your GitHub account. This can be explained by the difficulty to maintain and deploy multiple projects at the same time. These new settings allow you to follow a principle of least privilege in your workflows. In fact, the YAML file instructs the pipeline agent to check out this repository. Try running git config --list and see what's returned. For sensitive branches (such as the default one or any other branch wed want to protect), we can set rules to limit an account with Write permissions to directly push code to it by requiring the user to create a pull request. I have included your comment in the answer for more visibility. You can choose to disable GitHub Actions or limit it to actions and reusable workflows in your organization. First, let's check the protections applying to a repository: Here, there are protections enabled on the DEV and PROD environments. I gave below permissions on the GitHub and it worked. , if a secret is ever committed in cleartext to a repository, the only right option is to consider it compromised, revoke it, and generate a new one. 'git push --dry-run' is mentioned in this post as a way to check write access, when you have cloned. After the secrets extraction phase, the branch is deleted. In all cases, limiting the impact in the event that credentials used to access Azure DevOps or GitHub are compromised is not enough. If I am the owner of the repo, why do I not have write access? There's a link in there about changing to the Git Credential Manager if you prefer something like that. Interesting. For example, an application deployment can be triggered after a developer pushes a new version of the code to a repository. Here is a diagram from the kubernetes community that provides a clear depiction of the git workflow. The microsoft/azure-pipelines-tasks repository has been arbitrarily chosen. privacy statement. Jordan's line about intimate parties in The Great Gatsby? Instead, we will focus on what can be done when secrets are stored using dedicated CI/CD features. It is based on the concept of workflows, which automate the execution of code when an event happens. Why is the article "the" used in "He invented THE slide rule"? fatal: unable to access 'https://github.com/@username/repo.git/': The requested URL returned error: 403 If I am the owner of the repo, why do I not have write access? ). GitHub Classroom now offers a pre-made GitHub starter course (Public Beta), https://support.github.com/contact/feedback?category=education, Sunsetting API Authentication via Query Parameters, and the OAuth Applications API, Read/write for all scopes (current default), May 5, 2021: For 12 hours starting at 14:00 UTC, June 9, 2021: For 24 hours starting at 14:00 UTC, August 11, 2021: For 48 hours starting at 14:00 UTC. It should be noted that the tool could not be heavily tested on large scopes. A workflow in the GitHub terminology is a configurable and automated process that will run one or more jobs. The token has write permissions to a number of API endpoints except in the case of pull requests from forks which are always . Alternatively, you can enable GitHub Actions in your repository but limit the actions and reusable workflows a workflow can run. Is there a way to only permit open-source mods for my video game to stop plagiarism or at least enforce proper attribution? A snake biting its own tail. On a personal account repository, Collaborator permissions are at least required. joseprzgonzalez (joseprzgonzalez) October 29, 2021, 1:24pm 3 rahulsharma: Look for this setting: Clearing this setting will prevent Actions from approving PRs. To restrict access to specific tags or commit SHAs of an action or reusable workflow, use the same syntax used in the workflow to select the action or reusable workflow. - admin of repo but within an organisation, https://docs.github.com/en/authentication/connecting-to-github-with-ssh/checking-for-existing-ssh-keys, The open-source game engine youve been waiting for: Godot (Ep. If you're trying to push to a repository that doesn't exist, you'll get this error. fatal: unable to access, akin to a password (but can easily be revoked/regenerated), https://github.com/settings/tokens?type=beta, The open-source game engine youve been waiting for: Godot (Ep. On an organization repository, anyone can use the available secrets if they have the Write role or better. Use those credentials. A newly discovered security flaw in GitHub allows leveraging GitHub Actions to bypass the required reviews mechanism and push unreviewed code to a protected branch, potentially allowing malicious code to be used by other users or flow down the pipeline to production. 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. Error: Remote HEAD refers to nonexistent ref, unable to checkout, download the latest version on the Git website, About authentication with SAML single sign-on, Authorizing a personal access token for use with SAML single sign-on, Adding a new SSH key to your GitHub account. During our engagement, we used this personal token to get initial access to the GitHub organization of our target. To extract the variable groups secrets, Nord Stream proceeds as follows: If a project administrator account is used, a new repository is created and deleted at the end of the secrets extraction phase. Azure DevOps also offers the possibility to create connections with external and remote services for executing tasks in a job. To update the remote on an existing repository, see "Managing remote repositories". Furthermore, manual methods can be considered, such as deploying a scan pipeline or workflow on each private project or repository. On Windows, I ended up on this well known issue: this works only if you have an ssh key associated with your github account, That doesn't explain why you need write access just to clone a repository, As its currently written, your answer is unclear. Like in Azure DevOps, workflows are described by a YAML file and can be triggered when a specific action is performed, such as a push on a repository branch. Therefore, the secrets exposed need to be revoked and changed in every resource using them, which can be tedious. 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. I see you mentioned you have provided the access, I just tried all three ways they are working fine for me. I try to give the permissions into github web => repo => setting => actions. 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. One such tool is GitHub Actions GitHubs CI service which is used to build, test, and deploy GitHub code by building and running workflows from development to production systems. (select all read-write fields where possible) , do the same for (Account permissions ", You can use the steps below to configure whether actions and reusable workflows in a private repository can be accessed from outside the repository. In February 2020, to strengthen the security of our API, we deprecated API Authentication via Query Parameters and the OAuth Application API to avoid unintentional logging of in-transit access tokens. This is an organization-wide setting, which by default allows Actions to approve pull requests in existing organizations, and disallows it in newly created orgs. For private repositories: you can change this retention period to anywhere between 1 day or 400 days. 3 Jonno_FTW 7 mo. Making statements based on opinion; back them up with references or personal experience. The number of distinct words in a sentence. i am getting this err as soon as i enter git push -u origin main, brilliant man thanks, clearing cache following this doc did the trick :), Hi guys, I have the same problem but in a different context. If you're having trouble cloning a repository, check these common errors. Write permissions are commonly granted to many users, as that is the base permission needed to directly push code to a repo. There are a few solutions to this error, depending on the cause. Generate the pipeline YAML file based on secrets to be extracted and write it to the root directory. For more information, see permissions. 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. This kind of protection can for example restrict who can push to an existing branch or create new branches, which can prevent an attacker from triggering the secrets extraction workflow. Environment protection rules are rules that are applied to a specific environment. For more information about using the * wildcard, see "Workflow syntax for GitHub Actions.". As the PR is created, it cannot be merged since approval is required. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Access is allowed only from private repositories. In the coming months, we'll be removing these endpoints and authentication flow according to the following schedule: Please refer to this blog post on migrating to the replacement endpoints. Under Access, choose one of the access settings: You can configure the retention period for GitHub Actions artifacts and logs in your repository. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. There are a few common errors when using HTTPS with Git. You can disable GitHub Actions for your repository altogether. For public repositories: you can change this retention period to anywhere between 1 day or 90 days. The general idea is to allow authorized pipelines or workflows to get short-lived access tokens directly from a cloud provider, without involving any static secrets. git clone https://@github.com/orgName/repoName asked me for a password, I didn't go on, maybe it's recognized just as a new username so it was asking for a password. The options are listed from least restrictive to most restrictive. Thank you, it finally works. Scopes say nothing about a user's effective permissions and cannot allow them to do more than what they can do. While these credentials are securely stored when managed using dedicated features of the CI/CD systems, it is still possible to extract them in some cases. however for some of my remotes, this opens a password prompt & hangs indefinitely. role or better. ) then you will have all access and such an error should not occur. The issuer field corresponds to the URL of the GitHub OIDC provider. GitHub Docs: Using a token on the command line, @chris-c-thomas yep, edited url. It is possible to list them with Nord Stream: To extract a secure file, the following YAML file can be used: The role of the DownloadSecureFile@1 task is to download the specified secure file to the agent machine. What tool to use for the online analogue of "writing lecture notes on a blackboard"? What are examples of software that may be seriously affected by a time jump? [1] Obviously no one guarantees the approver actually reads the code, but at least now theres who to blame, right? 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. I tried multiple access tokens and they wouldn't work, then I finally decided to set the main "repo" scope and it finally worked. Duress at instant speed in response to Counterspell, Click on your Profile Icon (top-right on github website), Pick an expiration date from the menu or a custom one, From the menu at right select "Access> Read and Write", Input token description e.g. You'll want to follow them carefully so your config is set to use your token for the repos that require it. The service principal ID and key match the ones in the Azure portal. Since the base branch is considered trusted, workflows triggered by these events will always run, regardless of approval settings. In the repository settings you can configure whether the GITHUB_TOKEN should have read-write or read-only access. just ran git config --list, name and email are synced correct. That's why I had asked if when you originally cloned the repository you entered your token like this here? 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Use those credentials. In a service connection (can be used to store multiple kinds of secrets related to external services). Ah, yes, that was the underlying reason. Submit a pull request. Pull requests from public forks are still considered a special case and will receive a read token regardless of these settings. git remote set-url origin https://@github.com/organization_name/repo_name, In order to do the same while using the newer fine-grained token: Sometimes, users realize this is a bad practice and decide to push a commit removing these secrets. That is why a new repository is used, as an administrator can delete it without playing with permissions. there doesn't seem to be a non-interactive way to check if you have write access, even if you do have a clone of the repo. Could very old employee stock options still be accessible and viable? 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. But do not know how i must type it. Acceleration without force in rotational motion? Write access to the repository are not sufficient to bypass them. I am not able to push on git, although I am able to do other operations such as clone. My friend invited me to his repository, and I used his personal token while cloning it. Azure DevOps also offers some similar protections. You should push changes to your own fork of the repo and then open a pull request from your fork to the upstream and have your code reviewed and merged by another contributor. to get the data in the remote repository you need to push the code. To extract the secure files, Nord Stream performs the same actions as for the secrets in variable groups, except for the generation of the YAML pipeline. You can find the URL of the local repository by opening the command line and Its content can finally be exfiltrated to the pipeline execution output. 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. And, for testing, chose an expiration date " No Expiration ", to be sure it remains valid. This secrets extraction process was time-consuming when initially performed manually, so we developed a Python tool called Nord Stream1 to automate this process and help you, as a Red Teamer, obtain sensitive secrets. A pipeline is usually defined by a YAML file and can be automatically triggered when a specific action is performed, like a push to a repository branch, or manually triggered. For instance, a GitHub repository of an organization trusted by an Azure application could request an access token as this Azure identity to access resources or communicate with other services. The default permissions can also be configured in the organization settings. Such a service connection can be used in standard pipelines for authentication, for example with the AzureCLI task.
