2.20 Release notes

2.21

Enterprise Server 2.20.24

Download

March 01, 2021

Security fixes

  • HIGH: An improper access control vulnerability was identified in GitHub Enterprise Server that allowed authenticated users of the instance to gain write access to unauthorized repositories via specifically crafted pull requests and REST API requests. An attacker would need to be able to fork the targeted repository, a setting that is disabled by default for organization owned private repositories. Branch protections such as required pull request reviews or status checks would prevent unauthorized commits from being merged without further review or validation. This vulnerability has been assigned CVE-2021-22861. This issue was reported via the GitHub Bug Bounty Program.

  • HIGH: An improper access control vulnerability was identified in the GitHub Enterprise Server GraphQL API that allowed authenticated users of the instance to modify the maintainer collaboration permission of a pull request without proper authorization. By exploiting this vulnerability, an attacker would be able to gain access to head branches of pull requests opened on repositories of which they are a maintainer. Forking is disabled by default for organization owned private repositories and would prevent this vulnerability. Additionally, branch protections such as required pull request reviews or status checks would prevent unauthorized commits from being merged without further review or validation. This vulnerability has been assigned CVE-2021-22863. This issue was reported via the GitHub Bug Bounty Program.

  • HIGH: A remote code execution vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration of the underlying parsers used by GitHub Pages were not sufficiently restricted and made it possible to execute commands 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 has been assigned CVE-2020-10519 and was reported via the GitHub Bug Bounty Program.

  • LOW: A specially crafted request to the SVN bridge could trigger a long wait before failure resulting in Denial of Service (DoS).

  • Packages have been updated to the latest security versions.

Bug fixes

  • An informational message was unintentionally logged as an error during GitHub Enterprise Backup Utilities snapshots, which resulted in unnecessary emails being sent when backups were scheduled by cron jobs that listen for output to stderr.

  • While restoring a large backup, exception logging related to Redis memory exhaustion could cause the restore to fail due to a full disk.

  • When editing a wiki page a user could experience a 500 error when clicking the Save button.

  • An S/MIME signed commit using a certificate with multiple names in the subject alternative name would incorrectly show as "Unverified" in the commit badge.

  • Suspended user was sent emails when added to a team.

  • When uploading a new license file with a different number of seats from the previous license file, the seat difference was not correctly represented in the enterprise account Settings -> License page.

  • The "Prevent repository admins from changing anonymous Git read access" checkbox available in the enterprise account settings could not be successfully enabled or disabled.

  • During a leap year, the user was getting a 404 response when trying to view Contribution activity on a Monday.

August 25, 2020

Security fixes

  • CRITICAL: A remote code execution vulnerability was identified in GitHub Pages that could be exploited when building a GitHub Pages site. User-controlled configuration of the underlying parsers used by GitHub Pages were not sufficiently restricted and made it possible to execute commands 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. The underlying issues contributing to this vulnerability were identified both internally and through the GitHub Security Bug Bounty program. We have issued CVE-2020-10518.

  • MEDIUM: An improper access control vulnerability was identified that allowed authenticated users of the instance to determine the names of unauthorized private repositories given their numerical IDs. This vulnerability did not allow unauthorized access to any repository content besides the name. This vulnerability affected all versions of GitHub Enterprise Server prior to 2.22 and has been assigned CVE-2020-10517. The vulnerability was reported via the GitHub Bug Bounty program.

  • Packages have been updated to the latest security versions.

Enterprise Server 2.20.13

Download

August 10, 2020

Security fixes

  • CRITICAL: A remote code execution vulnerability was identified in GitHub Pages that could allow an attacker to execute commands as part building a GitHub Pages site. This issue was due to an outdated and vulnerable dependency used in the Pages build process. 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. To mitigate this vulnerability, Kramdown has been updated to address CVE-2020-14001.

  • HIGH: An attacker could inject a malicious argument into a Git sub-command when executed on GitHub Enterprise Server. This could allow an attacker to overwrite arbitrary files with partially user-controlled content and potentially execute arbitrary commands on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to access repositories within the GitHub Enterprise Server instance. However, due to other protections in place, we could not identify a way to actively exploit this vulnerability. This vulnerability was reported through the GitHub Security Bug Bounty program.

  • Packages have been updated to the latest security versions.

Bug fixes
