Release Notes for This Release

36.1.1

2024-10-11

This minor release fixes Carrier browser images(firefox, firefox_lite). Upgrade involves downloading new browser images and tagging them to match the current PrivX Carrier version.

This example shows how to upgrade the Firefox lite container image on PrivX Carrier 36.1:

docker pull public.ecr.aws/sshprivx/privx_browser_firefox_lite:36.1.1
docker tag public.ecr.aws/sshprivx/privx_browser_firefox_lite:36.1.1 public.ecr.aws/sshprivx/privx_browser_firefox_lite:36.1

36.1 is an incremental release with stability fixes.

Bug Fixes

  • [PX-7064] RDP-Bastion connections fail occationally due to /tmp folder permission error.

36.0

2024-09-02

36.0 is a major release with new features.

After this release, we provide security and stability fixes for PrivX 36.x, 35.x, and 34.x. Older versions are not officially supported. We recommend you upgrade as soon as you can if you are running an unsupported version.

Supported upgrade paths to this release are:

  • Upgrade with downtime: 33.x, 34.x, 35.x
  • Zero-downtime upgrade: 35.x

Important Notes for This Release

UEBA-Server upgrade required

If you are using UEBA Server from PrivX version 35 or earlier, you must upgrade the UEBA Server as follows:

  1. Before PrivX upgrade, disable UEBA Server.
  2. After PrivX upgrade, download and run the UEBA-Server install script. Doing this upgrades and restarts UEBA services.

Upgrade not supported with old PostgreSQL versions

You cannot upgrade to PrivX 35 or 36 if your PrivX deployment uses PostgreSQL version 10 or earlier. You must upgrade the PrivX database to PostgreSQL version 11.x or later before upgrading PrivX.

Note that PostgreSQL 11 has already reached EOL and PrivX support for it will be dropped soon, so we recommend upgrading to at least PostgreSQL 12.x or later.

If postinstall.sh fails to correctly determine your PostgreSQL version during upgrade, see this guide for troubleshooting.

API Endpoint GET /role-store/api/v1/roles Breaking Changes

Starting from PrivX version 36 the API endpoint GET /role-store/api/v1/roles will start using a default limit=50 and enforcing a maximum allowed limit=1000.

Due to these changes API clients can no longer rely on fetching all roles with one API call. The API clients are required to make multiple API calls with explicit limit and increasing offset until all roles - as indicated by the API response's count property - have been fetched.

Increased upgrade duration

Upgrading to this version may take somewhat longer, especially in environments with many hosts and principals.

Deprecation Warnings

Names with only spaces will be disallowed in PrivX 37

PrivX 36 and earlier allowed item names consisting of only spaces. Such names will be disallowed in PrivX 37 and later. We recommend you check your environment and rename any such items to names containing actual characters.

Names with only spaces were allowed in:

  • Hosts
  • Network Targets
  • Directories
  • Workflows
  • Cloud Log Collectors
  • External Token Providers
  • Identity Provider Clients
  • Target Domains

From PrivX 37 onward, items named with spaces only will continue to function. However, you will be unable to edit and save such items unless their names are also changed to something valid.

agent-proxy Deprecation Imminent

The agent-proxy functionality shall be removed in PrivX versions 38 and later.

The agent-proxy functionality allowed SSH clients using privx-agent to connect to Extender targets through ssh-proxy. In recent PrivX versions, you can instead use native SSH clients via SSH Bastion, as described here.

CentOS/RHEL 7 support Ended

CentOS 7 and RHEL 7 are no longer supported as PrivX platforms. If you are running PrivX on CentOS 7 or RHEL 7, see Migrate from EOL Operating Systems.

Amazon Linux 2 support Ending

PrivX aims to end installation support for Amazon Linux by June, 2025. See Migrate from EOL Operating Systems to migrate to a supported OS.

PostgreSQL 11.x Support Ending

PostgreSQL 11.x has reached end of life since Nov. 2023 and official support for this version will be ended in a future release.

SHA-1-Certificate End of Support Imminent
Support for certificates signed with SHA-1 shall be dropped in future PrivX releases.

By default PrivX will not trust certificates with SHA-1 signatures unless they are self-signed. Re-enabling trust for such certificates requires setting the GODEBUG=x509sha1=1 environment variable for PrivX microservices and tools.

Practical attacks against SHA-1 have been demonstrated in 2017 and publicly trusted Certificate Authorities have not issued SHA-1 certificates since 2015.

    • Note: This will be disabled in PrivX versions 37 and later. For more information about this issue, see Deprecation Warnings.

Notable API Changes

Secrets Manager API

  • New optional string property domain_name has been added to the target domain object. This property specifies the Windows domain name when using the legacy username format (DOMAIN\USER) instead of the upn format in the host account configuration.
  • New optional property sam_account_name has been added to the managed account object. This property is prerequisite for using the legacy username format with this managed account.
  • New boolean property disable_rdp_cert_auth has been added to the managed account object. This property disables the RDP certificate authentication for this target domain user causing RDP login to fall back to password authentication.

Local User Store API

  • New optional object array property attributes has been added to local user object. PrivX uses these attributes for role mapping and host principal username selection in a similar way AD user attributes are used.

    NOTE: Local user attributes can be modified with the users-manage API permission. As a consequence an admin user with users-manage API permission is able to influence which roles are implicitly mapped for local users. This affects only those roles that have mapping rules targetting to users in the local user directory.
