Dear Telerik Team,
We have purchased Telerik UI for ASP.NET AJAX UI 2010.1519. Now we are facing vulnerable issues as it is using jQuery 1.4.2.
One of the Telerik doc tells that
When Telerik upgraded jQuery version to 3.3.1, it faces incompatibilities with the MS AJAX framework and its __doPostBack() method. Due to which, Telerik downgraded jQuery version Telerik UI for ASP.NET AJAX R1 2019 - present are using a modified jQuery version 1.12.4 that includes security vulnerability backport fixes.
Is there a fix to overcome this issue other than upgrading the Telerik version to 2019 or greater?
Hi Kanimozhi,
Even if you disable the built-in jQuery and configure the controls to use an external newer version of jQuery, you should be aware that version 2010.1519 is vulnerable to some critical vulnerabilities that cannot be fixed. That is why it is strongly recommended to upgrade to at least 2020.1.114 to protect your server. You can find more information at:
