The Foundstone, Inc. advisory which covered this problem detailed the following method of verifying the vulnerability - full text of this advisory is available in the 'Credit' section of this entry:"It is easy to verify this vulnerability for a given system. Prefixing the path to web pages with "/servlet/file/" in the URL causes the file to be displayed without beingparsed or compiled. For example if the URL for a file "login.jsp" is:http://site.running.websphere/login.jspthen accessinghttp://site.running.websphere/servlet/file/login.jspwould cause the unparsed contents of the file to show up in the web browser."
