Vulnerability Description

An issue was discovered in SmartClient 12.0. Unauthenticated exploitation of blind XXE can occur in the downloadWSDL feature by sending a POST request to /tools/developerConsoleOperations.jsp with a valid payload in the _transaction parameter. NOTE: the documentation states "These tools are, by default, available to anyone ... so they should only be deployed into a trusted environment. Alternately, the tools can easily be restricted to administrators or end users by protecting the tools path with normal authentication and authorization mechanisms on the web server."
