  the URL of a malicious XSLT stylesheet when making a request to an XSQL page.");

  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.");
