SYMPTOMS

An update is available for Microsoft Commerce Server 2009 to fix the following issue in Commerce Server 2009.

When you use Commerce Server 2009 sample shopping sites (default site or contemporary site), the HTTP handler redirects the http requests to secure pages and redirects the https requests to nonsecure pages. A cross-site scripting (XSS) may occur during the client-side redirection.

For example, consider the following scenario. A client browser sends the following http request to the Commerce server:
http://<host name>/pages/<securepagename>.aspx?';alert(xss);

The client browser is redirected to the following page after the client-side JavaScript warning is run:
https://<host name>/pages/<securepagename>.aspx?

In this scenario, you experience a cross-site scripting (XSS) issue.

Note This issue also occurs in Commerce Server 2009 Extensibility Kit if you use Commerce Server 2009 Extensibility Kit to customize Commerce Server SharePoint Web Parts.

  7. The site displays the new file the next time that the page is loaded from the site. 

    Note If you do not follow the steps that are listed in Scenario2 to update the site, the site displays the old file when you reload it.

  4. Locate the updated source file in the CrossSiteScriptingEncoder.cs folder.
  5. Compile the Web Parts assemblies.
  6. If the custom site also uses the writeReview.aspx from Commerce Server 2009 default site, you have to follow the steps that are listed in Scenario 2 to change the writeReview.aspx files, and you have to reset to site definition by using SharePoint Designer.
