Summary
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 9.5.25, 10.4.14, 11.1.1 requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This is fixed in versions 9.5.25, 10.4.14, 11.1.1.

En TYPO3 versiones anteriores a la 9.5.25, 10.4.14, 11.1.1 la solicitud de recursos inv\u00e1lidos o inexistentes a trav\u00e9s de HTTP desencadena el manejador de errores de la p\u00e1gina que de nuevo podr\u00eda recuperar el contenido que se muestra como mensaje de error de otra p\u00e1gina. Esto lleva a un escenario en el que la aplicaci\u00f3n se llama a s\u00ed misma de forma recursiva, amplificando el impacto del ataque inicial hasta que se superan los l\u00edmites del servidor web. Esto se ha corregido en las versiones 9.5.25, 10.4.14 y 11.1.1"
