CVE-2014-7849

La implementación Role Based Access Control (RBAC) en JBoss Enterprise Application Platform (EAP) 6.2.0 hasta 6.3.2 no verifica correctamente las condiciones de la autorización, lo que permite a usuarios remotos autenticados añadir, modificar y desdefinir atributos de otra manera restringidos mediante el aprovechamiento del rol de mantenador (Maintainer).

It was discovered that the Role Based Access Control (RBAC) implementation did not sufficiently verify all authorization conditions that are required by the Maintainer role to perform certain administrative actions. An authenticated user with the Maintainer role could use this flaw to add, modify, or undefine a limited set of attributes and their values, which otherwise cannot be written to.

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. It was found that the RESTEasy DocumentProvider did not set the external-parameter-entities and external-general-entities features appropriately, thus allowing external entity expansion. A remote attacker able to send XML requests to a RESTEasy endpoint could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XML eXternal Entity attacks.
