Enterprise Server 3.9 release notes

HIGH: An attacker could cause unbounded resource exhaustion on the instance by sending a large payload to the Git server. To mitigate this issue, GitHub has limited the count of "have" and "want" lines for Git read operations. GitHub has requested CVE ID CVE-2024-5795 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An improper privilege management vulnerability allowed users to migrate private repositories without having appropriate scopes defined on the related personal access token. GitHub has requested CVE ID CVE-2024-5566 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized access in a public repository using a suspended GitHub App via a scoped user access token. This was only exploitable in public repositories while private repositories were not impacted. GitHub has requested CVE ID CVE-2024-5816 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could execute a Cross Site Request Forgery (CSRF) attack to perform write operations on a victim-owned repository in GitHub Enterprise Server by exploiting incorrect request types. A mitigating factor is that the attacker has to be a trusted user and the victim has to visit a tag in the attacker's fork of their own repository. GitHub has requested CVE ID CVE-2024-5815 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could disclose sensitive information from a private repository exploiting organization ruleset features. This attack required an organization member to explicitly change the visibility of a dependent repository from private to public. GitHub has requested CVE ID CVE-2024-6336 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could have unauthorized read access to issue content inside an internal repository via GitHub projects. This attack required attacker access to the corresponding project board. GitHub has requested CVE ID CVE-2024-5817 for this vulnerability, which was reported via the GitHub Bug Bounty program.

LOW: An attacker with read access to a project could use the REST API to view a list of all members in an organization, including members who had made their membership private. This vulnerability was reported via the GitHub Bug Bounty program.

LOW: An attacker could include MathJax syntax in Markdown to bypass GitHubs normal restrictions on CSS properties in Markdown. This vulnerability was reported via the GitHub Bug Bounty program.

Firewall port 9199, which linked to a static maintenance page used when enabling maintenance mode with an IP exception list, was opened unnecessarily.

When an instance hosted on Azure was upgraded with a hotpatch, the upgrade failed with an rsync error.

On an instance with GitHub Actions enabled, remote blob storage could fill up with large amounts of data because cleanup jobs were skipped on old hosts.

The memory limit for a Redis job was too low in some cases, causing the process to run out of memory.

In some cases, commands run in an administrative SSH shell were not written to the audit log.

When an administrator submitted a support data to GitHub Support, spokesd keys were incorrectly sanitized.

When log forwarding was enabled, some specific service logs, including babeld, gitauth, unicorn, and resqued, were duplicated.

During the initial boot of an instance, a data disk attached as /dev/sdb may not have been recognized as an available disk.

In some cases, the HAProxy kill_timeout setting caused service outages during upgrades or large transactions.

The ssh-audit-log.sh script did not effectively log SSH commands, and the ghe-sanitize-log.psed script inadequately sanitized password-related logs

The default MSSQL timeout of 8 seconds sometimes caused issues during administrator activities. The default timeout has been increased to 30 seconds.

For an instance running on Microsoft Azure, the user disk service failed to start because the attached volume could not be found.

Establishing a new GitHub Connect connection could fail with a 500 error.

When using ghe-migrator to migrate a repository, the links for pull requests merge commits were not imported.

In some cases, reading data from repositories with a large number of objects would result in timeout or error.

On an instance that restricts emails to verified domains, secret scanning emails would sometimes be sent to an unverified domain.

In some cases, on the "Files" tab of a pull request, a comment on the first line did not render.

Some organizations were not recognized as part of an instance's enterprise account.

On the "Code scanning" page of a repository, the branch filter did not correctly display all branches.

Users viewing the alerts index page experienced inconsistencies in rendering the closed alert state.

Organizations named "C" were incorrectly routed to the GitHub Enterprise Server contact page instead of their organization page.

Chat integrations required frequent reauthentication, as a result of new app installations overwriting previous ones.

On an instance in a cluster configuration, the ghe-spokesctl ssh command did not select the correct Nomad container when running a command within a git repository.

On an instance with a GitHub Advanced Security license, disabling and re-enabling GitHub Advanced Security for an organization resulted in redundant scans of some repositories.

When a user changes a repository's visibility to public, the user is now warned that previous Actions history and logs will become public as well.

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "管理コンソールへのアクセスのトラブルシューティング."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

When enabling CodeQL via default setup at scale, some checks related to GitHub Actions are omitted, potentially preventing the process from completing.

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see "インスタンスへのアップグレードに関する既知の問題."

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance's performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see "インスタンスへのアップグレードに関する既知の問題."

In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support.

On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance.

On an instance with the HTTP X-Forwarded-For header configured for use behind a load balancer, all client IP addresses in the instance's audit log erroneously appear as 127.0.0.1.

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. After upgrading from GitHub Enterprise Server 3.9, on an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "システム ログについて".

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "TLSの設定."

On an instance with GitHub Actions enabled, after an upgrade from GitHub Enterprise Server 3.8 or earlier, an internal exception could prevent successful completion of some operations, like upgrades or the configuration of new replica nodes for high availability. If this issue occurs, administrators may see the following error in /data/user/common/ghe-config.log.

Error occurred while executing servicing step 'Clone datatier login to secondary replica' for component CopyAvailabilityGroupSqlLogins during CopyAvailabilityGroupSqlLogins: Object reference not set to an instance of an object.

To resolve this issue, upgrade to the latest patch release of GitHub Enterprise Server.

On an instance in a cluster configuration, restoration of a backup using ghe-restore will exit prematurely if Redis has not restarted properly.

The HAProxy version has been updated in this release. You may encounter elevated error rates when HAProxy is upgraded as part of a hotpatch upgrade to a GitHub Enterprise Server instance. These elevated error rates should resolve within 5 minutes of the hotpatch being applied.

Please note, when performing a hotpatch upgrade to GitHub Enterprise Server version 3.9.7 or higher you will encounter this known issue only if you are hotpatching from GitHub Enterprise Server version 3.9.6 or lower .

The reply.[hostname] subdomain is falsely always displaying as having no ssl and dns record, when testing the domain settings via management console without subdomain isolation.

Admin stats REST API endpoints may timeout on appliances with many users or repositories. Retrying the request until data is returned is advised.

If a hotpatch upgrade requires the haproxy-frontend service to be restarted, the restart will hang if there are existing long-lived connections, such as browser web sockets or Git operations. No new connections will be accepted for up to 5 minutes. Any existing unfinished connections at this time will be disconnected.

HIGH: An attacker with the site administrator role could gain arbitrary code execution capability on the GitHub Enterprise Server appliance when configuring audit log streaming. GitHub has requested CVE ID CVE-2024-5746 for this vulnerability, which was reported via the GitHub Bug Bounty program.

These release notes previously indicated that GitHub Enterprise Server 3.9.8 contained fixes for the following issues:

• An improper authentication vulnerability that affected private mode, CVE-2023-6847
• An incorrect authorization vulnerability that affected issue comments, CVE-2023-51380

These fixes were included in GitHub Enterprise Server 3.9.7.

HIGH: An improper authentication vulnerability was identified in GitHub Enterprise Server that allowed a bypass of private mode by using a specially crafted API request. Private mode is the mechanism that enforces authentication for publicly-scoped resources. For more information, see "プライベートモードの有効化."

This vulnerability would allow unauthenticated attackers to gain access to various types of resources set as public on the instance. To exploit this vulnerability, an attacker would need network access to the GitHub Enterprise Server instance configured in private mode. This vulnerability was reported via the GitHub Bug Bounty program and assigned CVE-2023-6847.

HIGH: An attacker with access to a Management Console user account with the editor role could escalate privileges by making requests to the endpoint used for bootstrapping the instance, and then reset the root site administrator password. GitHub has requested CVE ID CVE-2023-46647 for this vulnerability, which was reported via the GitHub Bug Bounty program.

HIGH: A path traversal vulnerability was identified in GitHub Enterprise Server that allowed arbitrary file reading when building a GitHub Pages site. 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 was reported via the GitHub Bug Bounty program and assigned CVE-2023-46645.

MEDIUM: An insertion of sensitive information into log file vulnerability was identified in the log files for a GitHub Enterprise Server backend service that could permit an adversary in the middle attack when combined with other phishing techniques. To exploit this, an attacker would need access to the log files for the GitHub Enterprise Server instance, a backup archive created with GitHub Enterprise Server Backup Utilities, or a service which received streamed logs. GitHub has requested CVE ID CVE-2023-6746 for this vulnerability.

MEDIUM: Due to an insufficient entropy vulnerability, an attacker could brute force a user invitation to the Management Console. To exploit this vulnerability, an attacker would have needed knowledge that a user invitation was pending. This vulnerability was reported via the GitHub Bug Bounty program and assigned CVE-2023-46648.

MEDIUM: An attacker could maintain admin access via a race condition when an organization was converted from a user. GitHub has requested CVE ID CVE-2023-46649 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: Due to an improper access control, an attacker could view private repository names by enumerating check run IDs with the "Get a check run" API endpoint. This vulnerability did not allow unauthorized access to any repository content other than the name. GitHub has requested CVE ID CVE-2023-46646 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An attacker could maintain admin access to a transferred repository in a race condition by making a GraphQL mutation to alter repository permissions during the transfer. GitHub has requested CVE ID CVE-2023-6690 for this vulnerability, which reported via the GitHub Bug Bounty program.

MEDIUM: An insertion of sensitive information into log file in the audit log in GitHub Enterprise Server was identified that that could allow an attacker to gain access to the Management Console. To exploit this, an attacker would need access to the log files for the GitHub Enterprise Server instance, a backup archive created with GitHub Enterprise Server Backup Utilities, or a service which received streamed logs. GitHub has requested CVE ID CVE-2023-6802 for this vulnerability.

MEDIUM: A race condition in GitHub Enterprise Server allowed an outside collaborator to be added while a repository is being transferred. GitHub has requested CVE ID CVE-2023-6803 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: Improper privilege management allowed arbitrary workflows to be committed and run using an improperly scoped PAT. To exploit this, a workflow must have already existed in the target repo. GitHub has requested CVE ID CVE-2023-6804 for this vulnerability, which was reported via the GitHub Bug Bounty program.

MEDIUM: An incorrect authorization vulnerability was identified that allowed issue comments to be updated with an improperly scoped token. This vulnerability did not allow unauthorized access to any repository content as it also required contents.write and issues.read permissions. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2023-51379.

MEDIUM: An incorrect authorization vulnerability was identified that allowed issue comments to be read with an improperly scoped token. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2023-51380.

LOW: Pre-receive hooks have been further hardened against shell command injections.

LOW: To render interactive maps in an instance's web UI using Azure Maps, GitHub Enterprise Server has migrated from use of an unsecure Azure Maps API token to a more secure access token provided by role-based access control (RBAC) in Entra ID. After upgrading to this release, to re-enable interactive maps, an administrator must reconfigure authentication to Azure Maps in the Management Console. For more information, see "対話型マップの構成."

On an instance with Dependabot updates enabled, Dependabot relies on the node installation provided by the actions runner instead of dynamically downloading.

When adding a node to an instance, performance is improved during initial database replication.

An administrator can run the new ghe-check-background-upgrade-jobs command to ensure all upgrade jobs that run in the background have finished. This allows the administrator to know when they can start the next upgrade to their GitHub Enterprise Server instance.

To avoid negative effects on disk utilization, babeld log files have a maximum size of 15 GB.

Instance administrators can manage search indices for GitHub Discussions from the site admin dashboard.

To improve reliability of release uploads in low-bandwidth environments, the time-to-live (TTL) value of the token for uploading release assets has increased from 1 hour to 3 hours.

When using ghe-migrator prepare to import an archive, a missing schema.json file results in an UnsupportedArchive error rather than an UnsupportedSchemaVersion error.

The audit log now tracks all failed password attempts individually. Previously, duplicate failed password attempts in sequence within the same day would be grouped into one failed password attempt, with a count field.

Custom firewall rules are removed during the upgrade process.

The GitHub Packages npm registry no longer returns a time value in metadata responses. This was done to allow for substantial performance improvements. We continue to have all the data necessary to return a time value as part of the metadata response and will resume returning this value in the future once we have solved the existing performance issues.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "管理コンソールへのアクセスのトラブルシューティング."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

• level is now SeverityText.
• log_message, msg, or message is now Body.
• now is now Timestamp.
• Custom field names such as gh.repo.id or graphql.operation.name use semantic names.
• Log statements that the instance would previously write to auth.log, ldap.log, or ldap-sync.log now appear in containerized logs for github-unicorn if the statement originated from a web request, or in logs for github-resqued if the statement originated from a background job. For more information about containerized logs, see "システム ログについて."

For a full list of field mappings, download the OpenTelemetry attribute mapping CSV. This change is part of GitHub's gradual migration to internal semantic conventions for OpenTelemetry, and additional field names will change in upcoming releases.

On a configured instance, the name for the HAProxy service is now haproxy-frontend. Previously, the name was haproxy. Additionally, on an unconfigured instance, there is a new service named haproxy-pre-config. If your instance forwards logs to an external system, update your rules to reflect these changes. For more information, see "ログの転送" article

For an instance or organization with 2FA enabled, when a user sets up 2FA, GitHub Enterprise Server suggests an authenticator app (TOTP) by default.

When a person with administrative SSH access to an instance submits a support bundle using either the ghe-support-bundle or ghe-cluster-support-bundle utility, a period for log collection specified with the -p or --period no longer requires quotes to enclose the date value. For more information, see "コマンド ライン ユーティリティ."

To provide additional context within the web interface on an instance where Dependabot alerts are enabled, links to Dependabot alerts in an issue or pull request comment display an improved label and hovercard with alert details.

On an instance with Dependabot alerts enabled, people with write or maintain access to a repository can view or act on Dependabot alerts by default. Custom roles, the security manager role, organization permissions, and notification settings are not affected.

On an instance with a GitHub Advanced Security license and GitHub Connect enabled for the synchronization of actions from GitHub.com, CodeQL code scanning is up to 16% faster. For more information, see "アプライアンス用コードスキャンの構成."

On an instance with a GitHub Advanced Security license and email configured for notifications, users can receive notifications for secret scanning alerts by watching a repository and choosing "All activity" or "Security alerts". To continue receiving notifications for secret scanning alerts in GitHub Enterprise Server 3.9 and later, users must enable email notifications in the web interface at http(s)://HOSTNAME/settings/notifications under "Watching" by choosing "Email".

On an instance with a GitHub Advanced Security license, secret scanning alerts display whether detected tokens from GitHub are valid.

On an instance with a GitHub Advanced Security license, the enterprise and organization audit logs now display an event when an owner enables or disables a push protection for a custom pattern for a repository, organization, or the enterprise. For more information, see "Organization の Audit log をレビューする" and "エンタープライズの監査ログ イベント."

• Unsaved changes are now labeled with a "Modified" tag, and the "Save security settings" button now displays the total number of changes to save.
• While a security feature is being enabled, the "Security coverage" view shows a status of "Updating..." to inform you of the ongoing process.

For more information, see "セキュリティの概要について."

In the security overview's "Security risk" and "Security coverage" views, when a user selects a team from the "Team" drop-down or filters by team, results appear for repositories where the team has write or administrative access or has been granted access to security alerts. Previously, users could only view results for repositories where the team had administrative access or had been granted access to security alerts.

To provide more context within a project, users can share a deep link to a specific issue in a project to have the issue open in the project's side panel.

Organization owners can create up to five custom repository roles. Previously, the limit was three. For more information, see "カスタムリポジトリロールについて."

When transferring a repository, users can also rename the repository. For more information, see "リポジトリを移譲する."

If a user archives a repository, responses from the GraphQL API that include information about the repository now include an archivedAt value with a timestamp representing the archival date.

Before beginning a backup with GitHub Enterprise Server Backup Utilities 3.9.0 and later, the ghe-host-check utility will now perform a preflight check on the backup host to confirm the software version and disk space requirements. For more information, see the 3.9.0 release in the github/backup-utils repository on GitHub.com.

GitHub Enterprise Server Backup Utilities 3.9.0 allows administrators to view the progress of backup and restoration operations on the backup host using the ghe-backup-progress utility. For more information, see "インスタンスでのバックアップの構成."

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance's performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see "インスタンスへのアップグレードに関する既知の問題."

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see "インスタンスへのアップグレードに関する既知の問題." [Updated: 2023-08-11]

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. After upgrading from GitHub Enterprise Server 3.9, on an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "システム ログについて".

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "TLSの設定." [Updated: 2023-10-26]

The Management Console may get stuck in a loop showing "Checking requirements..." when attempting to download an update. It is safe to proceed the update process manually via the command line.

After restoration of a backup created using GitHub Enterprise Server Backup Utilities 3.7.0, 3.8.0, or 3.9.0, users may not be able to sign into the instance. To fix this issue, plus a bug that was preventing secret scanning encryption keys from being backed up, upgrade your backup host to use GitHub Enterprise Server Backup Utilities 3.9.1 and generate a new full backup using ghe-backup. For more information on using an existing backup, see "インスタンスのバックアップに関する既知の問題." [Updated: 2023-07-31]

After upgrading an existing instance to GitHub Enterprise Server 3.9, the Manage GitHub Enterprise Server API is unavailable. To enable the API, SSH into the instance and run the following commands.

Change to command-line utility for management of replication

• On an instance with multiple nodes, people with administrative SSH access to the instance should use ghe-spokesctl for management of Git replication instead of ghe-spokes. For more information, see "コマンド ライン ユーティリティ."

Dependency graph no longer ingests go.sum files

• Because go.sum files are not lock files and may result in false positive Dependabot alerts, on an instance with the dependency graph enabled, the go.sum files are no longer ingested for users' Go repositories. If Dependabot alerts are enabled, Dependabot will no longer alert users for vulnerabilities in a go.sum file's dependencies. The dependency graph continues to support go.mod files, the recommended format for Go projects. Use Go 1.17 or higher to ensure your go.mod file contains a comprehensive view of all direct and transitive dependencies. For more information, see "依存関係グラフについて."

Only GitHub Actions can publish a GitHub Pages site if source includes symbolic links

• To improve the security of an instance where users deploy sites using GitHub Pages, sites that contain symbolic links will no longer build outside of GitHub Actions. If a user's site is affected and a site administrator has configured email for the instance, the user will receive an email with instructions about how to fix the error. To continue using symbolic links in the site's source, the instance must be configured for GitHub Actions, and the user must write a GitHub Actions workflow to use as a publishing source. For more information, see "GitHub Pages について."
