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: 4.4EPSS: 0%CPEs: 1EXPL: 1CVE-2021-32638 – CodeQL runner: Command-line options that make GitHub access tokens visible to other processes are now deprecated
https://notcve.org/view.php?id=CVE-2021-32638
Github's CodeQL action is provided to run CodeQL-based code scanning on non-GitHub CI/CD systems and requires a GitHub access token to connect to a GitHub repository. The runner and its documentation previously suggested passing the GitHub token as a command-line parameter to the process instead of reading it from a file, standard input, or an environment variable. This approach made the token visible to other processes on the same machine, for example in the output of the `ps` command. If the CI system publicly exposes the output of `ps`, for example by logging the output, then the GitHub access token can be exposed beyond the scope intended. Users of the CodeQL runner on 3rd-party systems, who are passing a GitHub token via the `--github-auth` flag, are affected. • https://github.com/github/codeql-action/commit/58defc0652e935f6f2ffc70a82828b98d75476fb https://github.com/github/codeql-action/commit/88714e3a60e72ec53caa0e6a203652ee1f3fb1db https://github.com/github/codeql-action/releases/tag/codeql-bundle-20210304 https://github.com/github/codeql-action/security/advisories/GHSA-g36v-2xff-pv5m https://www.netmeister.org/blog/passing-passwords.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-214: Invocation of Process Using Visible Sensitive Information •
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 •
