WebSphere Misconfiguration: Servlets Served By Class Name

Java/JSP

Abstract

La aplicación está configurada para permitir que WebSphere sirva servlets por sus nombres de clase.

Explanation

Permitir que se sirvan servlets por su nombre de clase hace posible que cualquier atacante que conozca el nombre de un servlet lo invoque directamente, incluso cuando no esté asignado en el descriptor de implementación de la aplicación.

Por ejemplo, considere una aplicación que contiene un servlet llamado com.ibm.websphere.samples.MyServlet. Cuando serveServletsByClassnameEnabled en ibm-web-ext.xmi (para WAS V6 y versiones anteriores) o enable-serving-servlets-by-class-name en ibm-web-ext.xml (de WAS V7 en adelante) se establece en true, es posible llamar al servlet mediante la solicitud de:
http://www.example.com/SomeContextPath/servlet/com.ibm.websphere.samples.MyServlet.

Peor aún, dependiendo de la estructura del cargador de clases del servidor, un atacante puede invocar servlets desde otras aplicaciones hospedadas en la misma instancia de WebSphere.
