Descriptions

In Apache Struts 2.3.7 through 2.3.33 and 2.5 through 2.5.12, if an application allows entering a URL in a form field and built-in URLValidator is used, it is possible to prepare a special URL which will be used to overload server process when performing validation of the URL. NOTE: this vulnerability exists because of an incomplete fix for S2-047 / CVE-2017-7672.

En Apache Struts desde la versión 2.3.7 hasta la 2.3.33 y desde la 2.5 hasta la 2.5.12, si una aplicación permite la introducción de una URL en un campo de un formulario y se emplea URLValidator (integrado), es posible preparar una URL especial que será usada para sobrecargar el proceso del servidor cuando se lleva a cabo la validación de la URL. NOTA: Esta vulnerabilidad existe debido a una solución incompleta para S2-047 / CVE-2017-7672.
