Descriptions

The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled in Apache Tomcat 9.0.0.M1 to 9.0.4, 8.5.0 to 8.5.27, 8.0.0.RC1 to 8.0.49 and 7.0.0 to 7.0.84 when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.

El patrón de URL "" (la cadena vacía) que mapea exactamente al root de contexto no se gestionó correctamente en Apache Tomcat 9.0.0.M1 a 9.0.4, 8.5.0 a 8.5.27, 8.0.0.RC1 a 8.0.49 y 7.0.0 a 7.0.84 al emplearse como parte de una definición de limitación de seguridad. Esto provocó que el límite se ignorase. Por lo tanto, era posible que usuarios no autorizados obtuviesen acceso a recursos de la aplicación web que tendrían que haber estado protegidos. Solo se han visto afectadas las limitaciones de seguridad con un patrón URL de cadena vacía.
