When these secrets are used to connect to cloud services, a better option should be considered: using the OIDC (OpenID Connect) protocol. Have a question about this project? 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. 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: 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Does creating a token worked, as mentioned below?

I am trying to make a push to the repository that I have created for my UiPath project. performs the same actions as for the secrets in variable groups, except for the generation of the YAML pipeline. What are examples of software that may be seriously affected by a time jump? ", If you are accessing an organization that uses SAML SSO and you are using a personal access token (classic), you must also authorize your personal access token to access the organization before you authenticate. Making statements based on opinion; back them up with references or personal experience. The issuer field corresponds to the URL of the GitHub OIDC provider. 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. Secure files can be used to store sensitive data, such as SSH keys, PKCS#12 files or environment files. Variable groups store values and secrets that can be passed to a pipeline. To avoid this limitation, we may add future support using the GraphQL API. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

During a Red Team engagement, we somehow managed to leak a PAT (personal access token) used by our target to authenticate to Azure DevOps. 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. Available to private repositories only, you can configure these policy settings for organizations or repositories. Several tools can be used to monitor this kind of activity. In my case, I've used fine granted PAT, with all permissions, but somehow it doesn't work. 2022 Cider Security Ltd. All rights reserved. Azure DevOps also offers some similar protections.

GitHub Actions now lets you control the permissions granted to the GITHUB_TOKEN secret. Beta 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 information about private repositories, see "About repositories. Click the Pull or Deploy tab. suggestions from those who solved ran into and solved this before? 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.

GitHub offers similar features for developers with pipelines and secrets management, so we repeated this operation to get even more secrets and fully compromise our customer's GitHub environment. It is based on the concept of workflows, which automate the execution of code when an event happens. This is located in Actions -> General. Azure DevOps also offers the possibility to create connections with external and remote services for executing tasks in a job. 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. From there, we exploited our access to extract secrets stored at different places in projects, which allowed us to move laterally into Azure RM (Resource Manager) and GitHub. Click Save to apply the settings. Like secret variables in variable groups, secure files are protected resources. If you rely on using forks of your private repositories, you can configure policies that control how users can run workflows on pull_request events. Go to your local repository folder and find a hidden folder called ".git". A workflow YAML file for the above case would look like as follows: By pushing such a workflow, Nord Stream is able to automatically generate access tokens for Azure.

By default, all first-time contributors require approval to run workflows. A service connection holds credentials for an identity to a remote service. Personal access tokens are an alternative to using passwords for authentication when using the GitHub API. This article aims at describing the inner mechanisms of CI/CD pipeline secrets extraction by going through multiple examples on Azure DevOps and GitHub. 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. In November 2021 our team took part in the ZDI Pwn2Own Austin 2021 competition [1] with multiple entries. Each token can only access specific repositories. 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. GitHub currently supports two types of personal access tokens: fine-grained personal access tokens (in public beta at the time of writing) and personal access tokens (classic).

The microsoft/azure-pipelines-tasks repository has been arbitrarily chosen. For more information, see permissions. You can configure this behavior for a repository using the procedure below.
