J2EE Misconfiguration: Direct JSP Access

Java/JSP

Abstract

El acceso directo a Java Server Pages puede provocar una fuga de información del sistema, la divulgación del código fuente e incluso la ejecución de código arbitrario.

Explanation

El acceso directo a Java Server Pages (JSP) en aplicaciones creadas con marcos web, como Struts o Spring, que utilizan acciones o servlets para delegar solicitudes en JSP, puede generar excepciones no controladas y fugas de información del sistema. Los servidores de aplicaciones mal configurados o implementados han sido convencidos para filtrar los detalles del código fuente mediante solicitudes especialmente diseñadas, como http://host/page.jsp%00 o http://host/page.js%2570. Peor aún, si una aplicación permite a los usuarios cargar archivos arbitrarios, los atacantes pueden usar este mecanismo para cargar código malintencionado en forma de una JSP y solicitar que la página cargada haga que este código se ejecute en el servidor.

Ejemplo 1: En el siguiente ejemplo se muestra una restricción de seguridad mal construida que permite explícitamente el acceso directo a las JSP con un '*' en el nombre del rol, lo que indica que todos los usuarios pueden acceder a los recursos web correspondientes.


<security-constraint>
    <web-resource-collection>
        <web-resource-name>JSP Access for Everyone!</web-resource-name>
        <description>Allow any user/role access to JSP</description>
        <url-pattern>*.jsp</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>*</role-name>
    </auth-constraint>
</security-constraint>
