CVSS: 9.8EPSS: 0%CPEs: 2EXPL: 0CVE-2021-22869 – Improper access control in GitHub Enterprise Server allows self-hosted runners to execute outside their control group
https://notcve.org/view.php?id=CVE-2021-22869
An improper access control vulnerability in GitHub Enterprise Server allowed a workflow job to execute in a self-hosted runner group it should not have had access to. This affects customers using self-hosted runner groups for access control. A repository with access to one enterprise runner group could access all of the enterprise runner groups within the organization because of improper authentication checks during the request. This could cause code to be run unintentionally by the incorrect runner group. This vulnerability affected GitHub Enterprise Server versions from 3.0.0 to 3.0.15 and 3.1.0 to 3.1.7 and was fixed in 3.0.16 and 3.1.8 releases. • https://docs.github.com/en/enterprise-server%403.0/admin/release-notes#3.0.16 https://docs.github.com/en/enterprise-server%403.1/admin/release-notes#3.1.8 • CWE-287: Improper Authentication CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-22867 – Unsafe configuration options in GitHub Pages leading to path traversal on GitHub Enterprise Server
https://notcve.org/view.php?id=CVE-2021-22867
A path traversal vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration options used by GitHub Pages were not sufficiently restricted and made it possible to read files on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.1.3 and was fixed in 3.1.3, 3.0.11, and 2.22.17. This vulnerability was reported via the GitHub Bug Bounty program. • https://docs.github.com/en/enterprise-server%402.22/admin/release-notes#2.22.17 https://docs.github.com/en/enterprise-server%403.0/admin/release-notes#3.0.11 https://docs.github.com/en/enterprise-server%403.1/admin/release-notes#3.1.3 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2021-22866 – UI misrepresentation of granted permissions in GitHub Enterprise Server leading to unauthorized access to user resources
https://notcve.org/view.php?id=CVE-2021-22866
A UI misrepresentation vulnerability was identified in GitHub Enterprise Server that allowed more permissions to be granted during a GitHub App's user-authorization web flow than was displayed to the user during approval. To exploit this vulnerability, an attacker would need to create a GitHub App on the instance and have a user authorize the application through the web authentication flow. All permissions being granted would properly be shown during the first authorization, but in certain circumstances, if the user revisits the authorization flow after the GitHub App has configured additional user-level permissions, those additional permissions may not be shown, leading to more permissions being granted than the user potentially intended. This vulnerability affected GitHub Enterprise Server 3.0.x prior to 3.0.7 and 2.22.x prior to 2.22.13. It was fixed in versions 3.0.7 and 2.22.13. • https://docs.github.com/en/enterprise-server%402.22/admin/release-notes#2.22.13 https://docs.github.com/en/enterprise-server%403.0/admin/release-notes#3.0.7 • CWE-451: User Interface (UI) Misrepresentation of Critical Information CWE-1021: Improper Restriction of Rendered UI Layers or Frames •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-22865 – Improper access control in GitHub Enterprise Server leading to unauthorized read access to private repository metadata
https://notcve.org/view.php?id=CVE-2021-22865
An improper access control vulnerability was identified in GitHub Enterprise Server that allowed access tokens generated from a GitHub App's web authentication flow to read private repository metadata via the REST API without having been granted the appropriate permissions. To exploit this vulnerability, an attacker would need to create a GitHub App on the instance and have a user authorize the application through the web authentication flow. The private repository metadata returned would be limited to repositories owned by the user the token identifies. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.0.4 and was fixed in versions 3.0.4, 2.22.10, 2.21.18. This vulnerability was reported via the GitHub Bug Bounty program. • https://docs.github.com/en/enterprise-server%402.21/admin/release-notes#2.21.18 https://docs.github.com/en/enterprise-server%402.22/admin/release-notes#2.22.10 https://docs.github.com/en/enterprise-server%403.0/admin/release-notes#3.0.4 • CWE-285: Improper Authorization •

https://notcve.org/view.php?id=CVE-2021-22864
A remote code execution vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration options used by GitHub Pages were not sufficiently restricted and made it possible to override environment variables leading to code execution on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.0.3 and was fixed in 3.0.3, 2.22.9, and 2.21.17.
