We are pleased to announce the release of pfSense® software version 2.4.5, now available for new installations and upgrades!
pfSense software version 2.4.5 brings security patches, several new features, support for new Netgate hardware models, and stability fixes for issues present in previous pfSense 2.4.x branch releases.
pfSense 2.4.5-RELEASE updates and installation images are available now!
To see a complete detailed list of changes, see the Release Notes.
2.4.5 adds several new features, including:
- OS Upgrade: Base Operating System upgraded to FreeBSD 11-STABLE after FreeBSD 11.3
- Added sorting and search/filtering to several pages including the Certificate Manager, DHCP Leases, and ARP/NDP Tables.
- Added DNS Resolver (Unbound) Python Integration
- Added IPsec DH and PFS groups 25, 26, 27, and 31
- Changed UFS filesystem defaults to
noatimeon new installations to reduce unnecessary disk writes
autocomplete=new-passwordfor forms containing authentication fields to help prevent browser auto-fill from completing irrelevant fields
- Added new Dynamic DNS providers Linode and Gandi
For a complete list of new features, see the Release Notes.
Security / Errata
pfSense software release version 2.4.5 addresses several security issues:
- Potential cross-site scripting (XSS) vectors in several GUI pages
- A privilege escalation issue where an authenticated user granted access to the picture widget could run arbitrary PHP code or gain access to pages for which they otherwise would not have privileges
- Added a
UFSfilesystems on upgrade to address FreeBSD-SA-19:10.ufs
- Fixed the format of XMLRPC authentication failure messages so they can be acted upon by
Added a custom CSRF Error page with warnings and confirmation prompts before resubmitting potentially harmful data
Addressed FreeBSD Security Advisories & Errata Notices
For complete details about these issues, see the Release Notes.
Notable Bug Fixes
In addition to security fixes, pfSense software version 2.4.5 also includes important bug fixes.
- The default GUI certificate lifetime has been reduced to
825days, to comply with current standards. These standards are being enforced strictly on platforms such as iOS 13 and macOS 10.15. After upgrading to pfSense software version 2.4.5, a new compatible GUI certificate may be generated from the console or SSH with the command
pfSsh.php playback generateguicert
- Several IPsec VTI fixes, including improved handling of IPsec restarts breaking VTI routing
- Fixed several issues with custom view management in Status > Monitoring
- Fixed serial console terminal size handling issues
- Fixed privilege matching issues which may have prevented some users from accessing pages to which they should have had access, such as the User Manager
- Fixed an issue when resolving FQDN entries in aliases where some entries could be missing
For a complete list of corrected bugs, see the Release Notes.
IMPORTANT: Proceed with caution when upgrading pfSense software while COVID-19 travel restrictions are in effect.
During this time of travel limitations, remote upgrades of pfSense software should be carefully considered, and avoided where possible. Travel restrictions may complicate any repair of any issue, including hardware-related issues that render the system unreachable. Should these issues require onsite physical access to remedy, repair of the issue may not be possible while travel restrictions related to COVID-19 are in effect.
Due to the significant nature of the changes in this upgrade, warnings and error messages are likely to occur while the upgrade is in process. In particular, errors from PHP and package updates may be observed on the console and in logs. In nearly all cases these errors are a harmless side effect of the inconsistent state of the system during the upgrade from changes in the operating system, libraries, and PHP versions. Once the upgrade completes, the system will be in a consistent state again. Only errors which persist after the upgrade are significant.
Always take a backup of the firewall configuration prior to any major change to the firewall, such as an upgrade.
Do not update packages before upgrading pfSense! Either remove all packages or do not update packages before running the upgrade.
The upgrade will take several minutes to complete. The exact time varies based on download speed, hardware speed, and other factors such installed packages. Be patient during the upgrade and allow the firewall enough time to complete the entire process. After the update packages finish downloading it could take 10-20 minutes or more until the upgrade process ends. The firewall may reboot several times during the upgrade process. Monitor the upgrade from the firewall console for the most accurate view.
If the update check fails, or the update does not complete, run
pkg install -y pfSense-upgrade to ensure that
pfSense-upgrade is present.
Consult the Upgrade Guide for additional information about performing upgrades to pfSense software.
Upgrading to pfSense 2.4.5-RELEASE
Updating from an earlier pfSense 2.4.x release to 2.4.5-RELEASE is possible via the usual methods:
From the GUI:
- Navigate to System > Update
- Set Branch to Latest stable version (2.4.x)
- Click Confirm to start the upgrade process
From the console or ssh:
- Select option 13 OR select option 8 and run
See Upgrade Troubleshooting for the most up-to-date information on working around upgrade issues.
If the update system does not offer an upgrade to 2.4.5 or the upgrade will not proceed, take the following steps:
- Navigate to System > Updates
- Set Branch to Latest stable version
Refresh the repository configuration and upgrade script by running the following commands from the console or shell:
pkg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade
Planning for the upcoming 2.5.0 release
We are hard at work on the upcoming pfSense 2.5.0 release. Keep an eye on the draft copy of the 2.5.0 Release Notes for information about upcoming changes. 2.5.0 will bring a base OS upgrade to FreeBSD 12.x as well as upgrades to OpenSSL 1.1.1 and PHP 7.3.
The built-in load balancer has been deprecated from pfSense 2.5.0, and all related code has been removed, as it is not compatible with OpenSSL on FreeBSD 12.x. Plan migrations to alternate solutions such as the HAProxy package now.
Please note that pfSense version 2.5.0 WILL NOT require AES-NI. The original plan was to include a RESTCONF API in pfSense version 2.5.0, which for security reasons would have required hardware AES-NI or equivalent support. Plans have since changed, and pfSense 2.5.0 does not contain the planned RESTCONF API, thus the removal of the AES-NI requirement.
pfSense CE software is Open Source
For those who wish to review the source code in full detail, the changes are all publicly available in three repositories on GitHub:
- Main repository - the web GUI, back end configuration code, and build tools.
- FreeBSD source - the source code, with patches of the FreeBSD base.
- FreeBSD ports - the FreeBSD ports used.
Using the automatic update process is typically easier than reinstalling to upgrade. See the Upgrade Guide page for details.
