remote write access to repository not granted github actions

For information about private repositories, see "About repositories. 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! Has Microsoft lowered its Windows 11 eligibility criteria? Thanks to the persistCredentials options, the credentials are stored in the .git/config file. If there is a protection, we can try to remove it specifically for this branch and perform the secrets extraction phase normally. Sometimes, users realize this is a bad practice and decide to push a commit removing these secrets. GitHub Actions allows developers to store secrets at three different places: These secrets can then be read only from the context of a workflow run. Click Update from Remote to pull changes from the remote repository. You can always download the latest version on the Git website. 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. For more information, see "Cloning a repository.". For example, an application deployment can be triggered after a developer pushes a new version of the code to a repository. but unfortunately, no. [1] Obviously no one guarantees the approver actually reads the code, but at least now theres who to blame, right? This setting allows granting the token with restricted permissions . Or there is on other button/option? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. These permissions have a default setting, set in the organization or repository level. So thanks. For more information about GitHub Actions, see "Learn GitHub Actions.". It would be helpful if you actually said in the comment how you can edit these permissions. This also prevents developers from pushing unreviewed code to sensitive branches. Here is the guide: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/checking-for-existing-ssh-keys, If it is a private repository that is accessed using the classic Personal Access Token(PAT) try resetting the fetch and push url for the remote repo by running: 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. To automate the detection of unprotected secrets in all commits of a repository, tools like TruffleHog3 and Gitleaks4 can come in handy. 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. If you see this error when cloning a repository, it means that the repository does not exist or you do not have permission to access it. Interesting. (gdvalderrama adds in the comments: The max expiration date is 1 year and has to be manually set). Permission for any user with Write access to run a workflow in the repo. Can the Spiritual Weapon spell be used as cover? Every establishment comes out of image. remote: Write access to repository not granted. 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. Try and recreate a PAT(Personal Access Token) with, as scope, the repo ones. However, certain hardening settings can provide more granular control over access to repositories and thus to GitHub Actions secrets (see the Protections and protection bypass section below). Dealing with hard questions during a software developer interview, How to choose voltage value of capacitors. Managing access for a private repository in an organization On GitHub, navigate to the main page of the private repository. You can adjust the retention period, depending on the type of repository: When you customize the retention period, it only applies to new artifacts and log files, and does not retroactively apply to existing objects. thanks. Following this blog post, GitHub recently introduced a new setting to fix this vulnerability. Modifying this setting overrides the configuration set at the organization or enterprise level. 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. Each personal access token has one or multiple scopes such as8: An interesting scope is workflow, because it grants the ability to add and update GitHub Actions workflow files (we will detail the concept of workflow right after). By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. There is also still room for improvement to leave as few traces as possible and delete them when feasible. Available to private repositories only, you can configure these policy settings for organizations or repositories. It supports Azure DevOps and GitHub environments, and should work for most use cases of secret-related features. Under Fork pull request workflows from outside collaborators, select your option. The token has write permissions to a number of API endpoints except in the case of pull requests from forks which are always read. Also, was this the process you took when cloning to use the token? Have a question about this project? Thanks for contributing an answer to Stack Overflow! If you've previously set up SSH keys, you can use the SSH clone URL instead of HTTPS. For example: You can set the default permissions granted to the GITHUB_TOKEN. On a personal account repository, Collaborator permissions are at least required. 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. i'm not even getting to the point where i can enter my user and pass (token). For more information, see permissions. So does a compromise of a single user account mean the attacker can push code down the pipeline without restrictions? Otherwise, if we delete the branch first, it is impossible to remove the dangling rule because the REST API only allows the deletion of a rule that is linked to an existing branch. Secure files can be used to store sensitive data, such as SSH keys, PKCS#12 files or environment files. The subject identifier field is usually what we want to customize. BUT, one strange thing: 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? Learn more about setting the token permissions, For questions, visit the GitHub Actions community, To see whats next for Actions, visit our public roadmap. 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. You can enable GitHub Actions for your repository. How can I recognize one? to get the data in the remote repository you need to push the code. Sign in git remote set-url origin https://oauth2:@github.com/organization_name/repo_name. There are a few solutions to this error, depending on the cause. Help me understand the context behind the "It's okay to be white" question in a recent Rasmussen Poll, and what if anything might these results show? The required reviewers protection specifies who can approve the deployment if the associated environment is accessed. 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. GitHub Docs: Using a token on the command line, @chris-c-thomas yep, edited url. That token should start with ghp_: it should then authenticate you properly, allowing you to clone the repository, and push back to it. You need to change the url = https://github.com/ to SSH url that can find from GitHub repository(on git hub Web portal) cone menu as below picture. Connect and share knowledge within a single location that is structured and easy to search. To access GitHub, you must authenticate with a personal access token instead of your password. During our Red Team exercise, we managed to get access to an account which had read access over multiple Azure key vaults, allowing us to get other interesting secrets which eventually led to the compromise of some parts of our customer's cloud infrastructure. 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. At least in my case, it helped, since all the answers in this article did not work for me. #122 Closed See something that's wrong or unclear? Note that there is no matching branch for the moment. In fact, the YAML file instructs the pipeline agent to check out this repository. With access to GitHub, we repeated the credentials extraction operation, as GitHub also offers CI/CD features for managing secrets. 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. First, let's check the protections applying to a repository: Here, there are protections enabled on the DEV and PROD environments. Each token can only access resources owned by a single user or organization. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Kudos to GitHub for fixing this security flaw. If you're trying to push to a repository that doesn't exist, you'll get this error. The below link shows all three methods. Decode the execution output to display the secrets in cleartext. The exception to this behavior is where an admin user has selected the Send write tokens to workflows from pull requests option in the GitHub Actions settings. On an organization repository, anyone can use the available secrets if they have the. The same YAML file is generated but to specify an environment, the environment parameter is added. Console . Organization admins can now disallow GitHub Actions from approving pull requests. Is that the actual error returned or did you edit it slightly to remove info? Thank you @rahulsharma yes I was using GIT credentials. Going on repository -> setting -> Collaboration and team, I can see I gave below permissions on the GitHub and it worked. 15/09: Reported to GitHub bug bounty program15/09 : First response from GitHub22/09: Triage22/09: Payout23/09: Approval for write-up. Click the Pull or Deploy tab. After that, you can get a list of all the available branches from the command line: Then, you can just switch to your new branch: All GitHub docs are open source. I'm the admin. By default, Nord Stream goes through all the environments but it is possible to specify a selection of them. In expiration: it should say No expiration. @gdvalderrama Thank you for your feedback.

In the end, it allowed us to compromise our customer's infrastructure by obtaining a lot of credentials. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Fine-grained tokens, The max expiration date is 1 year and has to be manually set. I am trying to make a push to the repository that I have created for my UiPath project. I created a fine-grained token for this repo but still, nothing. Is variance swap long volatility of volatility? Hope this helps! See something that's wrong or unclear? For private repositories: you can change this retention period to anywhere between 1 day or 400 days. Thank you, it finally works. For instance, the Azure Resource Manager type allows the pipeline to log in to an Azure tenant as a service principal. Indeed, it is common to find secrets directly in the source code of the applications or in the configuration files. This procedure demonstrates how to add specific actions and reusable workflows to the allow list. I use the Personal Access Token (Classic) in Travis CI to push tags, and I can push tags normally on January 16, 2023 But then came the 403 error now. For now, when the tool creates a new branch, it is not able to know if there is any protection applying to the branch before pushing it to the remote repository. remote: Write access to repository not granted. Lets see. 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. Well it's likely to be along the same lines. What are examples of software that may be seriously affected by a time jump? This code can also go down the CI/CD pipeline, run unreviewed in the CI, or find itself in the companys production environment. 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. This is already supported by GitHub Actions and should be added as an Azure DevOps feature in 2023 Q2 (public preview)9. The corresponding credentials can be exfiltrated with the following YAML pipeline file: In this YAML file, an external GitHub repository is referenced. 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. How to create GitHub repository under an organization from the command-line? Connect and share knowledge within a single location that is structured and easy to search. Furthermore, manual methods can be considered, such as deploying a scan pipeline or workflow on each private project or repository. For more information, see "Creating a personal access token. For more information, see "Disabling or limiting GitHub Actions for your organization" or "Enforcing policies for GitHub Actions in your enterprise.". Try once with SSH and confirm if that works? Under "Actions permissions", select an option. Azure DevOps also offers some similar protections. Change color of a paragraph containing aligned equations. Clean the logs as much as possible (useful for Red Team engagements). Commit means the code is sent to your local instance of repository and not in the remote instance(actual git instance) of repository. These systems help teams and developers by enforcing automation when building, testing and deploying applications. There are a few common errors when using HTTPS with Git. For example, it is possible to ask it to include the repo, context (environment) and ref (branch) claims: Once this kind of OIDC trust relationship is configured, if an attacker knows its existence and can deploy a workflow under the required conditions, they could also generate access tokens that can be used to interact with Azure services through the different APIs. If all else fails, make sure that the repository really exists on GitHub.com! Why do we kill some animals but not others? ), How to push to organisation's repo on github, Remote origin already exists on 'git push' to a new repository, Remove directory from remote repository after adding them to .gitignore, GitHub "fatal: remote origin already exists", Git, fatal: The remote end hung up unexpectedly, gpg failed to sign the data fatal: failed to write commit object [Git 2.10.0], Unable to push remote repository to my repo, Message "Support for password authentication was removed. Personal access tokens are an alternative to using passwords for authentication when using the GitHub API. Thats not the one to be used. This can be restricted to repository secrets only: Here, it is possible to observe the workflow at work: For environment secrets, the same operation can be performed. This issue has grown ever since Git*Hub has brought token authentication into account. Finally, the deployment branch protection restricts which branches can deploy to a specific environment using branch name patterns. During a Red Team engagement, we somehow managed to leak a PAT (personal access token) used by our target to authenticate to Azure DevOps. To update the remote on an existing repository, see "Managing remote repositories". Azure DevOps also offers the possibility to create connections with external and remote services for executing tasks in a job. By clicking Sign up for GitHub, you agree to our terms of service and You can choose to disable GitHub Actions or limit it to actions and reusable workflows in your organization. This security issue was reported to GitHub through their bug bounty program. For example, for the REPO_SECRET secret, it will generate the following YAML file: The double-base64 encoding is again used because GitHub also detects when secrets are about to be displayed in the workflow logs and prevents this by modifying the output with * characters, just like on Azure DevOps. But it says the above error. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. This can be explained by the difficulty to maintain and deploy multiple projects at the same time. For example, the actions/checkout action would not be accessible. By default, when you create a new repository in your personal account, workflows are not allowed to create or approve pull requests. (select all read-write fields where possible) , do the same for (Account permissions However mine were already set and I still have the error, select a project goto Settings > Actions > General , can find there "Workflow permissions". Visit your Git, go to your repository, click on Clone repository, there youll see the option to generate credentials. 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're not using GitHub Actions, disable it for the entire organization or for specific repositories where it's not required. On GitHub, navigate to the main page of the private repository. I've created my PAT and in fact, I can commit and push other Incorrect or out of date credentials will cause authentication to fail. Any user that can push code to the repo (Write permissions or higher), can create a workflow that runs when code is pushed.
