Descriptions

The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M3 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.

El método setGlobalContext en org/apache/naming/factory/ResourceLinkFactory.java en Apache Tomcat 7.x en versiones anteriores a 7.0.68, 8.x en versiones anteriores a 8.0.31 y 9.x en versiones anteriores a 9.0.0.M3 no considera si los que llaman a ResourceLinkFactory.setGlobalContext están autorizados, lo que permite a usuarios remotos autenticados eludir las restricciones de SecurityManager previstas y leer o escribir a datos de aplicación arbitrarios, o provocar una denegación de servicio (interrupción de aplicación), a través de una aplicación web que establece un contexto global manipulado.

A security manager bypass flaw was found in Tomcat that could allow remote, authenticated users to access arbitrary application data, potentially resulting in a denial of service.
