When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

RedShield customers are protected as the HTTP PUTS verb is blocked by default. Any customers running Apache Tomcat on Windows please contact RedShield support.
