****X-XSS-Protection: 1; mode block not working against reflected XSS****

In ASP.NET Application the Microsoft report viewer response/request is vulnerable

like ApplicationName/Reserved.ReportViewerWebControl.axd?ReportSession=ok5gmqqbjz2pn5isiqacf045&ControlID=ea0a9e89e25e44d78f4a5851d4cfdbeb&Culture=1033&UICulture=1033&ReportStack=1&OpType=SessionKeepAlive&TimerMethod=KeepAliveMethodcntPlcHolder_ReportViewer1TouchSession038999%3balert(1)%2f%2f705&CacheSeed=Mon%20Apr%2009%202018%2014%3A06%3A40%20GMT%2B0530%20(IST)

Check 38999%3balert(1)%2f%2f705 string after TouchSession0 which causes reflected XSS attack. now is anyone know solution for this.
