Barracuda Web Application Firewall Release Notes - Version 11.0.1.006 (Pre-requisite : 10.1.1.006, Release : November 2021)

Before installing a new version of firmware:

1. Make a backup of your configuration using the ADVANCED > Backup page.
2. Read all release notes that apply to versions more recent than the one currently running on your system.

The update process typically takes only a few minutes after the update is applied. Make sure you do not reboot the machine during this time. The progress bar would indicate the status but in some rare cases, the progress bar may not be seen. If this happens, please revisit the URL after five minutes. If the process takes longer, contact Barracuda Networks Technical Support to investigate.

CAUTION:

• The upgrade when coming from 10.1.0.x to 11.0.0, will be a major one and the upgrade process, may take more than 10 minutes in case the configuration is large, specially with many servers configured. Please do not reboot the machine while the upgrade process is in progress
• Downgrading to a previous major version (like from 11.0.0.x to 10.1.0.x) is NOT recommended. Please contact Barracuda Networks Technical Support if you are thinking about attempting a firmware downgrade, and make sure that you have carefully gone through the known issues sections for the earlier firmware versions.

Backups taken AFTER a firmware revert or downgrade (such as from 11.0.0.x to 10.1.0.x), may not be compatible for use after a subsequent firmware upgrade (such as from 10.1.0.x back up to 11.0.0.x), so make sure that you back up your configuration settings BEFORE actually start any firmware change process (either upgrade OR revert). If a feature is available in later versions and the configuration is in place for that feature, a downgrade does retain the configuration. This means that after the downgrade, the configuration pertaining to such a feature might be visible but would not take effect.

After restoring your settings from a backup, you should always REBOOT to make sure that they take effect.

NOTE: Before upgrading a virtual machine, it is highly recommended to take a snapshot of that virtual machine.

Barracuda Web Application Firewall Product Activation

If this is a new system, you must activate your Energize Updates subscription prior to initial use. Your Energize Updates subscription includes access to Technical Support, new firmware releases and ongoing security definitions updates.
To activate your Barracuda Web Application Firewall subscription:

1. Using your Web browser, go to the BASIC > Status page.
2. In the Subscription Status section, check the Energize Updates entry. If Energize Updates is Not Activated, click the activation link to be redirected to the Barracuda Networks Product Activation page. Complete activation of your subscription(s).

If it is connected to the Internet, your Barracuda Web Application Firewall automatically updates its activation status after you reload the browser page when viewing the BASIC > Status page. If it is not connected to the Internet yet, enter the activation code provided after completing the details on the Barracuda Networks Product Activation page. Click Activate. If the code is correct, the Barracuda Web Application Firewall will update its activation status.

If a server is added with a hostname, the Barracuda Web Application Firewall will automatically create server entries for all IP addresses that resolve to the configured host name. Deleting the first server that was added with the hostname, will now delete all the automatically created server entries. [BNWF-25536]

• With the OpenSSL1.1.0, certificates signed with MD5 are no longer supported. Please replace such certificates with SHA1/SHA256 signed certificates before upgrading to 11.0.0.x. If an upgrade is done without replacing these certificates, services using them will go down and rollbacks will occur. [BNWF-31980]
• Attackdef 1.172 is shipped with this firmware. It has changes relevant to the firmware's interoperability with the Barracuda Block Listed IP database. [BNWF-32541]

Version 11.0.0.007

The Barracuda Web Application Firewall version 11.0.0 is a major upgrade version to the 10.1.1 release and has the following important enhancements and fixes:

• Client Side Protection

  Barracuda Networks augments security with complete support for Content Security Policy and Sub Resource Integrity validations.

  • Content Security Policy is used to control the behavior of the client’s browser. A full featured wizard supporting all CSP directives enables administrators to control the resources that can be loaded in the client’s browsers and direct the behavior of the various elements, tags and other aspects of the web pages within the client’s browser. Directives such as frame-ancestors help in protecting against Click Jacking attacks. [BNWF-46278] [BNWF-46278] [BNWF-25949]
  • Sub Resource Integrity is a security feature that enables browsers to verify that resources they fetch are delivered without unexpected manipulation. This protects the applications from supply chain attacks that may be targeted at resources such as JavaScript, images and other content loaded from 3^rd party servers. [BNWF-46278]

  These capabilities can be deployed in Report Only mode or in Block mode. In the report only mode all the violations of the policies are reported to the Barracuda Threat Intelligence Service and can be viewed using the Barracuda Threat Intelligence Service Dashboard.

• Advanced Bot Protection

  Barracuda Advanced Bot Protection capabilities have been protecting many of our customers against many types of automated attacks. Barracuda Networks continues to enhance the capabilities to detect and protect against automated attacks.

  • Credential stuffing attack protection has been enhanced to support applications that communicate credentials via JSON / AJAX requests or HTTP Basic Authentication mechanisms. [BNWF-33998]
  • Brute Force Policy can now be triggered by matching a set of text patterns in the HTTP response body [BNWF-33840]

• Security & Access Control

  In this release, additional protection for APIs and Web Socket have been introduced along with multiple other enhancements.

  • JWT Validation: JSON Web Tokens (JWT) are a common mechanism of representing claims securely especially in the context of APIs. With version 11.0, Barracuda WAF adds support for validating JWT token issued by Authorization Server. This feature is available on Barracuda WAF 660 and above models. [BNWF-46375]
  • Web Socket Security: Traffic on WebSocket can now be inspected for protocol violation and other exploits by WebSocket Security feature on WAF. Admisitrators can configure the WebSocket security profile by navigating to Websites > WebSocket Security. [BNWF-25386]
  • Tarpit: Suspicious clients can be tarpitted (slowed down) for time interval configurable from UI. [BNWF-46274]
  • Single Log Out (SLO) support for SAML: SAML for Access Control has been enhanced to support SLO where logout response for any of the participating applications resident on the WAF will send logout command to all participating SSO applications. [BNWF-33520]

• Traffic Management
  • HTTP/2: With this release, Barracuda WAF adds support for HTTP/2 for WAF-to-server communication in addition to the client-to-WAF communication that has been supported from earlier releases. [BNWF-25380]
  • Direct Server Return: Barracuda WAF service can now be configured behind a Load Balancer service with Direct Server Return. This capability are used in rare scenarios where traffic from the server has to be bypassed due to application considerations. This requires changes on the web server as well. [BNWF-46377]
  • IP Address from TCP Options (additional CDN Support): In many cases where the Barracuda WAF is deployed behind a CDN, the actual IP address of the client is encapsulated in TCP Options field by the CDN infrastructure. Barracuda WAF supports reading of Client IP and Port from TCP Options Address field. [BNWF-46376]

• System Management
  • Auto Configuration Engine: Customers with Barracuda Advanced Bot Protection license can now use the statistical and machine learning enabled configuration recommendation engine. This engine analyzes traffic patterns to recommend configurations that would make the existing deployments more secure. [BNWF-46303]
  • SAML for Role Based Administration: All user identity stores that support SAML, such as Azure AD or Microsoft AD/FS, can be integrated with Barracuda WAF to enable Role Based Administrator for the WAF administration. [BNWF-32912]
  • ABP Dashboard Enhancements: Advanced Analytics dashboard is updated to improve the performance and visualizations. [BNWF-47616]
  • API Enhancements: REST API v3.x now support performing IP reputation look ups. [BNWF-31932]
