Descriptions

In GLPI from version 9.1 and before version 9.4.6, any API user with READ right on User itemtype will have access to full list of users when querying apirest.php/User. The response contains: - All api_tokens which can be used to do privileges escalations or read/update/delete data normally non accessible to the current user. - All personal_tokens can display another users planning. Exploiting this vulnerability requires the api to be enabled, a technician account. It can be mitigated by adding an application token. This is fixed in version 9.4.6.

En GLPI desde la versión 9.1 y versiones anteriores a 9.4.6, cualquier usuario de la API con derecho READ en el tipo de elemento User tendrá acceso a la lista completa de usuarios cuando consulte apirest.php/User. La respuesta contiene: - Todos los api_tokens los cuales pueden ser usados para escalar privilegios o leer/actualizar/eliminar datos que normalmente no son accesibles para el usuario actual. - Todos los tokens personales pueden mostrar la planificación de otros usuarios. La explotación de esta vulnerabilidad requiere que la API esté habilitada y una cuenta de técnico. Puede ser mitigada al agregar un token de aplicación. Esto es corregido en la versión 9.4.6.
