Certain versions of the IBM webSphere application server ship wITh a vulnerabilITy which allows malicious users to view the source of any document which resides in the web document root directory.
This is possible via a flaw which allows a default servlet (different servlets are used to parse different types of content, JHTML, HTMl, JSP, etc.) This default servlet will display the document/page wIThout parsing/compiling IT hence allowing the code to be viewed by the end user.
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 being
parsed or compiled. For example if the URL for a file "login.jsp" is:
http://sITe.running.websphere/login.jsp
then accessing
http://sITe.running.websphere/servlet/file/login.jsp
would cause the unparsed contents of the file to show up in the web browser."
