As of JK 1.2.49, the implicit mapping functionality has been removed and all mappings must now be via explicit configuration. Only mod_jk is affected by this issue. The ISAPI redirector is not affected.\n\nThis issue affects Apache Tomcat Connectors (mod_jk only): from 1.2.0 through 1.2.48.\n\nUsers are recommended to upgrade to version 1.2.49, which fixes the issue.\n\nHistory\n2023-09-13 Original advisory\n\n2023-09-28 Updated summary\n\n"

El componente mod_jk de Apache Tomcat Connectors en algunas circunstancias, como cuando una configuración incluía \"JkOptions +ForwardDirectories\" pero la configuración no proporcionaba mounts explícitos para todas las posibles solicitudes de proxy, mod_jk usaría un mapeo implícito y mapearía la solicitud al primer worker definido. Un mapeo implícito de este tipo podría dar como resultado la exposición no deseada del estado del worker y/o eludir las restricciones de seguridad configuradas en httpd. A partir de JK 1.2.49, la funcionalidad de asignación implícita se eliminó y todas las asignaciones ahora deben realizarse mediante una configuración explícita. Sólo mod_jk se ve afectado por este problema. El redirector ISAPI no se ve afectado. Este problema afecta a los conectores Apache Tomcat (solo mod_jk): desde la versión 1.2.0 hasta la 1.2.48. Se recomienda a los usuarios actualizar a la versión 1.2.49, que soluciona el problema. Historia: 2023-09-13. Aviso original: 2023-09-28. Resumen actualizado"
