workarounds: Disable J-Web, or limit access to only trusted hosts which may not be compromised by cross-site attacks. For example, deploy jump hosts with no Internet access that use anti-scripting techniques to mitigate potential threats. Alternately, use a dedicated client and dedicated Web browser that is not used to access other sites.
