When selecting an item with Enter key, the rawEvent propagation is not canceled and if a button with submit behavior is on the page, it is clicked.  https://www.screencast.com/t/sGVXL2baFj

Including this script to the page can be a temporary workaround: 
var _onEnterKeyOld = Telerik.Web.UI.RadComboBox.prototype._onEnterKey;
    Telerik.Web.UI.RadComboBox.prototype._onEnterKey = function (e) {
        _onEnterKeyOld.call(this,e);
        e.preventDefault()
    }

Greetings!

Description:

I have found a Cross-Site Scripting issue in the rich text editor, RadEditor. This is not in a body where user provides certain strings, rather it's in the text properties which gets sent along with the user input, such as font-style. The developers were able to follow the filtering mechanisms given in at https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/prevent-cross-site-scripting-(xss), but it provides protection for the inputs given in <textarea>, and for the properties values. Hence XSS is still possible

 

Steps for Reproduction:

 

1. Open up the text editor {{Screenshot 2020-09-23 at 12.08.51 PM.png}}

2. Input a string and change its font style.

3. Click on submit and intercept the request. {{Screenshot 2020-09-23 at 12.14.45 PM.png}}

4. Now we need to modify the request body for parameter of texteditor's ID. You may notice that the font-style is set and sent by using a <span>.

RadEditor1=%253cspan%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e

Change parameter 'RadEditor1's value with the following:

RadEditor1=%253cspan%20onmouseover%253d%2522document.body.innerHTML%253d%2527ioioioioioioioioo%2527%252bdocument.cookie%2522%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e

5. Submit and notice the 200 OK response. Now go to the text editor and notice that the string texttexttext can be seen. {{Screenshot 2020-09-23 at 12.24.18 PM.png}}

6. Put a mouse cursor on the string and notice that it gets changed to ioioioioioioioioo<domainCookies>.

When track changes disabled the backspace is OK:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it successfully appended the line (2) with line (1) (where there was a space available). 
When track changes enabled the backspace does not work as expected:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it removes the end of the character in line (1).

 Hello,

I have noticed the changes in your website, demos and documentation, but not all seems to work well on IE 11.

In the new interface of

 https://docs.telerik.com/devtools/aspnet-ajax/introduction?_ga=2.16776693.2130593711.1599296842-392310183.1565849466

 the left menu dissapear after more clicks (IE11)

However, in ASP.net AJAX demos, the new interface is not looking good on IE 11

For example,  https://demos.telerik.com/aspnet-ajax/orgchart/examples/expandcollapse/defaultcs.aspx

The old interface was looking great, I had no problems at all, any control

I hope I will not have the same problems in my ASP.net application...

Hi Team,

 

I'm using Telerik.Web.UI Version 2020.2.617

I have integrated it and added a reference in my web application, asked me to upgrade the version of Assemblies "System.Web.Extension.dll" and "System.Core.dll" has to be upgraded to version 4.0, I did that too, Now I'm getting an error while I'm running or doing build "The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)", Assembly it is referring to "System.Web.Script.Services", same error is coming for other attributes like "ScriptMethod, ScriptMethodAttribute"

For the Key word "this" it is throwing as below error

It is throwing an error for "System.Linq.Expressions"

 

  

 

Can anyone help me out on this how to resolve these bugs.

 

Regards

P L P Kumar

This issue seems fixed for AzureAD while it is not for WSFederation authentication

It seems the final solution is to manually remove the entries with null/empty key from the submitted form

Simple reproducible is attached to illustrate the problem.

A workaround may be replacing RadButtons that invokes such postbacks with regular buttons and using a form decorator

Alternatively, you can simply disable the handler URL encryption

You can also put the following in the global.asax file to prevent the version from rendering on the page markup
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
			System.Web.HttpContext.Current.Items["_!TelerikVersionStampRendered"] = true;
        }
or you can add the same line in a global Page_Load handler (e.g., in a base page class or in the master page your project uses)

Images that reside in the grid will get resized (scaled down with about 3-5 %) which might cause issues, specially if exporting bar-codes, thus the bar-code scanners won't be able to read them.

Current workaround is to use the Telerik Documents Processing Library  and build the table manually where the images are inserted without changing the size.

Here is an example:

        protected void RadGrid1_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e)
        {
            Telerik.Web.UI.ExportInfrastructure.Table table = e.ExportStructure.Tables[0];

            Workbook workbook = new Workbook();
            workbook.Worksheets.Add();

            Worksheet worksheet = workbook.ActiveWorksheet;


            foreach (var row in table.Rows)
            {
                if (row.Index > 1)
                {
                    worksheet.Rows[row.Index - 1].SetHeight(new RowHeight(55, true));
                }

                foreach (var cell in row.Cells)
                {
                    if (row.Index == 1 || cell.ColIndex != 2)
                    {
                        worksheet.Cells[cell.Index.Y - 1, cell.Index.X - 1].SetValue(cell.Value.ToString());
                    }
                    else
                    {
                        FloatingImage image = new FloatingImage(worksheet, new CellIndex(cell.Index.Y - 1, cell.Index.X - 1), 0, 0);
                        Stream stream = File.Open(Server.MapPath(cell.Value.ToString()), FileMode.Open);
                        using (stream)
                        {
                            image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "jpg");
                        }
                        worksheet.Shapes.Add(image);
                    }
                }
            }

            byte[] data;

            using (MemoryStream ms = new MemoryStream())
            {
                XlsxFormatProvider xlsProvider = new XlsxFormatProvider();
                xlsProvider.Export(workbook, ms);
                data = ms.ToArray();
            }

            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

Twice this week, my Asp.net project would not compile because of a Telerik.Web.UI.dll link error. I run into this problem frequently, Telerik is very flakey. My last bug report was this compile problem with another Telerik file.

The solution to both compile problems is to clear the Properties/licenses.licx file. As least the second time, I knew right where to go without wasting time searching the web. A couple hours wasted on the first one on Monday.  I suppose I can expect to clear it Friday again when the compile fails on Telerik.

The Properties/licenses.licx is re-populating itself causing the compile to fail on this Telerik issue. Why have a licenses.licx if it always breaks the software? Your support says, clear the file - they know it causes endless problems.

There is no fix on my side for the this problem, Telerik must do something about the licenses.licx problem in an update.

I have these Telerik compiler warnings. The entire list is Telerik created, misleading and annoying.

A JavaScript error is thrown when the Print dialog is being disposed.
Error message:
Uncaught TypeError: Cannot read property 'dispose' of undefined

Workaround:
Enable the external dialogs of the Editor/ImageEditor and modify dispose() function of the Print.ascx dialog:

 

Print.ascx

				dispose: function ()

					this._attachHandlers(false);

					this._printBtn.dispose();
					this._cancelBtn.dispose();

					$IE.Print.callBaseMethod(this, "dispose");

Hi, I have trouble with RadScriptManager. I would like combine scripts on page to only one file. But when I enabled it, my site threw javascript error on loading.
Please help me fix it, it would also be better if you can help me understand what happened.

First image is what I set up for RadScriptManager

Secondary image is the error.



I have no idea what's Telerik.Web.UI.Point, I haven't used it anywhere.

Please help me get this error out & fix it.
Thank you.
