CVE-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 •
CVE-2021-22864 – Unsafe configuration options in GitHub Pages leading to remote code execution on GitHub Enterprise Server
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. This vulnerability was reported via the GitHub Bug Bounty program. • https://docs.github.com/en/enterprise-server%402.21/admin/release-notes#2.21.17 https://docs.github.com/en/enterprise-server%402.22/admin/release-notes#2.22.9 https://docs.github.com/en/enterprise-server%403.0/admin/release-notes#3.0.3 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
