Descriptions

Insufficient Input Validation in Web Applications operating on Business-DNA Solutions GmbH’s TopEase® Platform Version <= 7.1.27 on an object’s date attribute(s) allows an authenticated remote attacker with Object Modification privileges to insert an unexpected format into date fields, which leads to breaking the object page that the date field is present.

Una comprobación de entrada insuficiente en las aplicaciones web que operan en la plataforma TopEase® de Business-DNA Solutions GmbH, versiones anteriores a 7.1.27 incluyéndola, en los atributos de fecha de un objeto, permite a un atacante remoto autenticado con privilegios de Modificación de Objetos insertar un formato inesperado en los campos date, lo que conlleva a una ruptura de la página del objeto que el campo de fecha está presente
