Teleport 15.3.6

on GitHub

Description

This release contains fixes for several high-severity security issues, as well as numerous other bug fixes and improvements.

Security Fixes

[High] Unrestricted redirect in SSO Authentication

Teleport didn’t sufficiently validate the client redirect URL. This could allow an attacker to trick Teleport users into performing an SSO authentication and redirect to an attacker-controlled URL allowing them to steal the credentials. #41834.

Warning: Teleport will now disallow non-localhost callback URLs for SSO logins unless otherwise configured. Users of the tsh login --callback feature should modify their auth connector configuration as follows:

version: vX
kind: (saml|oidc|github)
metadata:
  name: ...
spec:
  ...
  client_redirect_settings:
    allowed_https_hostnames:
      - '*.app.github.dev'
      - '^\d+-[a-zA-Z0-9]+\.foo.internal$'

The allowed_https_hostnames field is an array containing allowed hostnames, supporting glob matching and, if the string begins and ends with ^ and $ respectively, full regular expression syntax. Custom callback URLs are required to be HTTPS on the standard port (443).

[High] CockroachDB authorization bypass

When connecting to CockroachDB using Database Access, Teleport did not properly consider the username case when running RBAC checks. As such, it was possible to establish a connection using an explicitly denied username when using a different case. #41823.

[High] Long-lived connection persistence issue with expired certificates

Teleport did not terminate some long-running mTLS-authenticated connections past the expiry of client certificates for users with the disconnect_expired_cert option. This could allow such users to perform some API actions after their certificate has expired. #41827.

[High] PagerDuty integration privilege escalation

When creating a role access request, Teleport would include PagerDuty annotations from the entire user’s role set rather than a specific role being requested. For users who run multiple PagerDuty access plugins with auto-approval, this could result in a request for a different role being inadvertently auto-approved than the one which corresponds to the user’s active on-call schedule. #41837.

[High] SAML IdP session privilege escalation

When using Teleport as SAML IdP, authorization wasn’t properly enforced on the SAML IdP session creation. As such, authenticated users could use an internal API to escalate their own privileges by crafting a malicious program. #41846.

We strongly recommend all customers upgrade to the latest releases of Teleport.

Other fixes and improvements

• Fixed access request annotations when annotations contain globs, regular
  expressions, trait expansions, or claims_to_roles is used. #41936.
• Added AWS Management Console as a guided flow using AWS OIDC integration in
  the "Enroll New Resource" view in the web UI. #41864.
• Fixed spurious Windows Desktop sessions screen resize during an MFA ceremony. #41856.
• Fixed session upload completion with large number of simultaneous session
  uploads. #41854.
• Fixed MySQL databases version reporting on new connections. #41819.
• Added read-only permissions for cluster maintenance config. #41790.
• Stripped debug symbols from Windows builds, resulting in smaller tsh and
  tctl binaries. #41787
• Fixed passkey deletion so that a user may now delete their last passkey if
  the have a password and another MFA configured. #41771.
• Changed the default permissions for the Workload Identity Unix socket to 0777
  rather than the default as applied by the umask. This will allow the socket to
  be accessed by workloads running as users other than the user that owns the
  tbot process. #41754
• Added ability for teleport-event-handler to skip certain events type when
  forwarding to an upstream server. #41747.
• Added automatic GCP label importing. #41733.
• Fixed missing variable and script options in Default Agentless Installer
  script. #41723.
• Removed invalid AWS Roles from Web UI picker. #41707.
• Added remote address to audit log events emitted when a Bot or Instance join
  completes, successfully or otherwise. #41700.
• Simplified how Bots are shown on the Users list page. #41697.
• Added improved-performance implementation of ProxyCommand for Machine ID and
  SSH. This will become the default in v16. You can adopt this new mode early by
  setting TBOT_SSH_CONFIG_PROXY_COMMAND_MODE=new. #41694.
• Improved EC2 Auto Discovery by adding the SSM script output and more explicit
  error messages. #41664.
• Added webauthn diagnostics commands to tctl. #41643.
• Upgraded application heartbeat service to support 1000+ dynamic applications. #41626
• Fixed issue where Kubernetes watch requests are written out of order. #41624.
• Fixed a race condition triggered by a reload during Teleport startup. #41592.
• Updated discover wizard Install Script to support Ubuntu 24.04. #41589.
• Fixed systemd unit to always restart Teleport on failure unless explicitly stopped. #41581.
• Updated Teleport package installers to reload Teleport service config after
  upgrades. #41547.
• Fixed file truncation bug in Desktop Directory Sharing. #41540.
• Fixed WebUI SSH connection leak when browser tab closed during SSH connection
  establishment. #41518.
• Fixed AccessList reconciler comparison causing audit events noise. #41517.
• Added tooling to create SCIM integrations in tctl. #41514.
• Fixed Windows Desktop error preventing rendering of the remote session. #41498.
• Fixed issue in the PagerDuty, Opsgenie and ServiceNow access plugins that
  causing duplicate calls on access requests containing duplicate service names.
  Also increases the timeout so slow external API requests are less likely to
  fail. #41488.
• Added basic Unix workload attestation to the tbot SPIFFE workload API. You
  can now restrict the issuance of certain SVIDs to processes running with a
  certain UID, GID or PID. #41450.
• Added "login failed" audit events for invalid passwords on password+webauthn
  local authentication. #41432.
  Fixed Terraform provider issue causing the Provision Token options to default
  to false instead of empty. #41429.
• Added support to automatically download CA for MongoDB Atlas databases. #41338.
• Fixed broken "finish" web page for SSO Users on auto discover. #41335.
• Allow setting Kubernetes Cluster name when using non-default addresses. #41331.
• Added fallback on GetAccessList cache miss call. #41326.
• Fixed DiscoveryService panic when auto-enrolling EKS clusters. #41320.
• Added validation for application URL extracted from the web application launcher request route. #41304.
• Allow defining custom database names and users when selecting wildcard during test connection when enrolling a database through the web UI. #41301.
• Fixed broken link for alternative EC2 installation during EC2 discover flow. #41292
• Updated Go to v1.21.10. #41281.
• Updated user management to explicitly deny password resets and local logins to
  SSO users. #41270.
• Fixed fetching suggested access lists with large IDs in Teleport Connect. #41269.
• Prevents cloud tenants from updating cluster_networking_config fields keep_alive_count_max, keep_alive_interval, tunnel_strategy, or proxy_listener_mode. #41247.
• Added support for creating Okta integrations with tctl #41888.
