Solution: 

Until Oracle changes the default behavior for the XSQL servlet to disallow client supplied stylesheets, you can workaround this problem as follows. Add allow-client-style='no' on the document element of every xsql page on your server.
This plug-in tests for this vulnerability using a sample page, airport.xsql, which is supplied with the Oracle XSQL servlet. Sample code should always be removed from production servers.

Risk factor : High";
