"The version of SAP NetWeaver Application Server Java installed on the remote host is affected by an information 
disclosure vulnerability. Due to improper limitation of a pathname to a restricted directory, internal metadata files 
could be accessed via manipulated URLs. An unauthenticated attacker could exploit this vulnerability by inserting 
arbitrary path components in the request, allowing unauthorized access to sensitive application metadata. This results 
in a partial compromise of the confidentiality of the information without affecting the integrity or availability of 
the application server.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
