Descriptions

The 'crowd-application' plugin module (notably used by the Google Apps plugin) in Atlassian Crowd from version 1.5.0 before version 3.1.2 allowed an attacker to impersonate a Crowd user in REST requests by being able to authenticate to a directory bound to an application using the feature. Given the following situation: the Crowd application is bound to directory 1 and has a user called admin and the Google Apps application is bound to directory 2, which also has a user called admin, it was possible to authenticate REST requests using the credentials of the user coming from directory 2 and impersonate the user from directory 1.

El módulo del plugin "crowd-application" (empleado principalmente por el plugin Google Apps) en Atlassian Crowd, desde la versión 1.5.0 y antes de la versión 3.1.2, permitía que un atacante suplantase a un usuario de Crowd en peticiones REST pudiendo autenticarse en un directorio vinculado a una aplicación que emplee esa característica. En la siguiente situación: la aplicación Crowd está enlazada al directorio 1 y tiene un usuario llamado admin y la aplicación Google Apps está enlazada al directorio 2, que también tiene un usuario llamado admin, era posible autenticar peticiones REST empleando las credenciales del usuario que viene del directorio 2 y suplanta al usuario del directorio 1.
