      "value": "MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the FieldCc parameter of /Mondo/lang/sys/Forms/AddressBook.aspx. The FieldCc value is not properly sanitized when processed via a GET request and is reflected inside a <script> block in the JavaScript variable var CCFieldProvided. By supplying a crafted payload that terminates the existing LoadCurAddresses() function, inserts attacker-controlled script, and comments out remaining code, a remote attacker can execute arbitrary JavaScript in a victim’s browser when the victim attempts to send an email. Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user."

      "value": "Versiones de MailEnable anteriores a la 10.54 contienen una vulnerabilidad de Cross-site Scripting (XSS) reflejado en el parámetro FieldCc de /Mondo/lang/sys/Forms/AddressBook.aspx. El valor de FieldCc no se depura correctamente cuando se procesa a través de una solicitud GET y se refleja dentro de un bloque [script_tag] en la variable JavaScript var CCFieldProvided. Al proporcionar una carga útil manipulada que termina la función LoadCurAddresses() existente, inserta script controlado por el atacante y comenta el código restante, un atacante remoto puede ejecutar JavaScript arbitrario en el navegador de una víctima cuando esta intenta enviar un correo electrónico. La explotación exitosa puede redirigir a las víctimas a sitios maliciosos, robar cookies no HttpOnly, inyectar HTML o CSS arbitrario y realizar acciones como el usuario autenticado."
