An issue was discovered in Zimbra Collaboration (ZCS) 9.0 and 10.0. A Cross-Site Scripting (XSS) vulnerability exists in the CalendarInvite feature of the Zimbra webmail classic user interface, because of improper input validation in the handling of the calendar header. An attacker can exploit this via an email message containing a crafted calendar header with an embedded XSS payload. When a victim views this message in the Zimbra webmail classic interface, the payload is executed in the context of the victim's session, potentially leading to execution of arbitrary JavaScript code.

Summary
  • (es) Se descubrió un problema en Zimbra Collaboration (ZCS) 9.0 y 10.0. Existe una vulnerabilidad de cross site scripting (XSS) en la función CalendarInvite de la interfaz de usuario clásica del correo web de Zimbra, debido a una validación de entrada incorrecta en el manejo del encabezado del calendario. Un atacante puede aprovechar esto a través de un mensaje de correo electrónico que contenga un encabezado de calendario manipulado con un payload XSS incorporado. Cuando una víctima ve este mensaje en la interfaz clásica del correo web de Zimbra, el payload se ejecuta en el contexto de la sesión de la víctima, lo que potencialmente conduce a la ejecución de código JavaScript arbitrario.
