Descriptions

Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying edit check permissions on WebDAV copy actions. The WebDAV endpoint was not properly checking the permission on a WebDAV COPY action. This allowed an authenticated attacker with access to a read-only share to put new files in there. It was not possible to modify existing files.

Nextcloud Server en versiones anteriores a 9.0.52 & ownCloud Server en versiones anteriores a 9.0.4 no están verificando correctamente los permisos de comprobación de edición en las acciones de copia de WebDAV. El punto final WebDAV no comprueba correctamente el permiso en una acción WebDAV COPY. Esto permitió a un atacante autenticado con acceso a un recurso compartido de solo lectura para poner allí nuevos archivos. No fue posible modificar los archivos existentes.
