Description:    SAP Netweaver have a web interface for accesing filesystem of the portal, users can make "feedbacks" of
                files, input passed to the content of these feedbacks is not properly sanitised before being returned 
to the user. 
                This can be exploited to execute arbitrary HTML and script code in a user's browser session in context 
of an affected site


Solution:       This issue can be solved activating "Secure Editing" in Portal
(System Configuration -> System Configuration -> Knowledge management (in detailed Navigation) -> Utilities -> Editing 
-> HTML Editing)
