Features and fixes include

  • Apache Commons Text library updated to version 1.10.0 to mitigate CVE-2022-42889 (2.7.5)

  • Applied security updates and additional bug fixes. (2.7.4)

  • Windows Authentication - Kerberos is available for end users launching sessions via the Assigned Sessions list. (2.7.3)

  • Automated Sign-On for Host Access is a new feature that allows an end user to receive a one time, time limited passcode to sign on to back-end host systems. The passcode is associated with the end user's host userid and only issued if the host has authorized the connection. Note: This feature requires some changes on the host. (2.7.2)

  • Host Access for the Cloud sessions can be exported and imported using the MSS Admin Console. (2.7.2)

  • Support added for IPv6 in dual stack (IPv6/IPv4) environments (2.7.2)

  • Thymeleaf library upgraded to mitigate a critical CVE. (2.7.2)

  • Users can now double-click to select a word in the Web Client terminal. (2.7.1)

  • Log4j library has been upgraded to version 2.17.1 to mitigate multiple CVEs. (2.7.1)

  • Information on how to run HACloud as a dedicated, non-administrative, user (2.7.1)

Changes in Behavior

  • Host Access for the Cloud is adopting new deployment models, a virtual appliance and Linux RPMs. This change will simplify deployment, security, scaling, high availability and ongoing maintenance. A preview will be provided before the official release.

    To ease into this change, Host Access for the Cloud will continue to support existing installation types. In our major release, Windows customers will have the option of migrating to the appliance or running the appliance along with their Windows-based MSS installations. In subsequent releases, older installation types will no longer be supported. All of our customers can be assured that Host Access for the Cloud will continue to provide all the support necessary to transition to the new virtual appliance.

  • The Java runtimes used in HACloud and MSS have been updated to Java 11. When using the "no JRE" installer, you must now provide a Java 11 JRE. (2.7.3)

  • Based on customer feedback, the Web Client paste settings Wrap to next field on current line and Wrap to next line are now enabled by default in newly created sessions. (2.7.3)

  • The updated MSS Administrative Console supports Chrome, Edge or Firefox. You can no longer access the Admin Console using Internet Explorer 11. (2.7.3)

  • The property name used to enable extensions is now called extensions_enabled, containing an underscore. The previous hyphenated value of extensions-enabled is deprecated and will be removed in an upcoming release. (2.7.2)

  • IP address SAN entries are no longer added to generated self signed certificates. This change was made to avoid problems resulting from dynamic IP addresses. IP addresses can still be explicitly added during install if necessary. (2.7.2)

  • All servers in an MSS cluster must now be running on the same platform, for example either all Windows servers or all Linux servers. (2.7.2)

  • Due to Microsoft continuing to retire Internet Explorer 11, our ability to resolve IE 11 browser specific issues will be limited after June 2022. We will continue to support IE 11 on versions of HACloud that currently support it, based on the Product Support Lifecycle, but will be removing support for IE 11 in HACloud 3 and greater. (2.7.1)

  • To help prevent cross-site request forgery attacks, the default SameSite attribute on the session server cookie has been updated from None to Lax. This change may affect the JavaScript SDK and SAML authentication behind a load balancer. You can edit this attribute if needed. See Setting the SameSite Attribute. (2.7.1)
