Descriptions

Design document functions which receive a user http request object may expose authorization or session cookie headers of the user who accesses the document.

These design document functions are:
*   list
*   show
*   rewrite
*   update

An attacker can leak the session component using an HTML-like output, insert the session as an external resource (such as an image), or store the credential in a _local document with an "update" function.

For the attack to succeed the attacker has to be able to insert the design documents into the database, then manipulate a user to access a function from that design document.

Workaround: Avoid using design documents from untrusted sources which may attempt to access or manipulate request object's headers

Las funciones de diseño de documentos que reciben un objeto de solicitud http de usuario pueden exponer los encabezados de cookies de sesión o de autorización del usuario que accede al documento. Estas funciones del documento de diseño son: * lista * mostrar * reescribir * actualizar. Un atacante puede filtrar el componente de la sesión utilizando una salida similar a HTML, insertar la sesión como un recurso externo (como una imagen) o almacenar la credencial en un documento local con una función de "actualización". Para que el ataque tenga éxito, el atacante debe poder insertar los documentos de diseño en la base de datos y luego manipular a un usuario para que acceda a una función desde ese documento de diseño. Workaround: evite el uso de documentos de diseño de fuentes no confiables que puedan intentar acceder o manipular los encabezados de los objetos de solicitud.
