A client of ours runs a security scanner daily on a website.  One page on the site has the RadDatePicker control.  When the scanner runs, it brings up t

Inner Exception Type: System.ArgumentException
Inner Exception
Invalid JSON primitive: ;WAITFOR DELAY '00:00:28'-- .
 
Inner Source:
System.Web.Extensions
 
Inner Stack Trace:
at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)
at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)
at Telerik.Web.UI.RadDatePicker.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection)
at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
 

I looked at the scanner form input data and found this:

ContentPlaceHolder1_applicationManager1_sessionsearchresults1_Criteria1_radTo_ClientState: 1';WAITFOR DELAY '00:00:28'--

I know this value is not valid JSON, but I'm unsure how to proceed.  I tried to reproduce this problem on the form itself but have been unable to.  Has anyone experienced this problem?

No answers yet. Maybe you can help?
