Descriptions

The IIS/ISAPI specific code in the Apache Tomcat JK ISAPI Connector 1.2.0 to 1.2.42 that normalised the requested path before matching it to the URI-worker map did not handle some edge cases correctly. If only a sub-set of the URLs supported by Tomcat were exposed via IIS, then it was possible for a specially constructed request to expose application functionality through the reverse proxy that was not intended for clients accessing Tomcat via the reverse proxy.

El código específico IIS/ISAPI en Apache Tomcat JK ISAPI Connector, de la versión 1.2.0 a la 1.2.42, que normalizaba la ruta solicitada antes de emparejarla al mapa URI-worker no gestionaba algunos casos perimetrales (edge cases) correctamente. Si solo un subconjunto de las URL soportadas por Tomcat estuviese expuesto mediante IIS, una petición especialmente construida podría exponer funcionalidades de la aplicación mediante el proxy inverso que no estaba pensado para que los clientes accediesen a Tomcat a través de él.
