Teleport 9.3.4

on GitHub

Description

This release of Teleport contains multiple security, bug fixes and improvements.

Escalation attack in agent forwarding

When setting up agent forwarding on the node, Teleport did not handle unix socket creation in a secure manner.

This could have given a potential attacker an opportunity to get Teleport to change arbitrary file permissions to the attacker’s user.

Websockets CSRF

When handling websocket requests, Teleport did not verify that the provided Bearer token was generated for the correct user.

This could have allowed a malicious low privileged Teleport user to use a social engineering attack to gain higher privileged access on the same Teleport cluster.

Denial of service in access requests

When accepting an access request, Teleport did not enforce the maximum request reason size.

This could allow a malicious actor to mount a DoS attack by creating an access request with a very large request reason.

Auth bypass in moderated sessions

When initializing a moderated session, Teleport did not discard participant’s input prior to the moderator joining.

This could prevent a moderator from being able to interrupt a malicious command executed by a participant.

Actions

We recommend upgrading Auth, Proxy, SSH and Kubernetes agents.

Users should backup the Teleport cluster, then follow the standard Teleport upgrade procedure.
