            Description


            Fetching the URL

            http://localhost:8080/auctionMonitor/auctionMonitor.jspx

            causes extremely hight CPU consumption, possibly until the maximum stack depth is reached.

            This could be used as a denial of service attack. Other DOS attacks on ICEfaces are possible, but this one is particularly inexpensive for the attacker because a single HTTP request causes significant CPU load.

              It looks like D2DViewHandler will delegate *.jspx pages to Sun RI handler which triggers a forward to the same page, thus going into an infinite loop.

              Stop overridding the JSP compiler for *.jspx pages because Sun RI's ViewHandler relies on the JSP compiler to execute them.

              Commit #16642 for the trunk.
