Descriptions

Nextcloud Server before 9.0.55 and 10.0.2 suffers from a creation of folders in read-only folders despite lacking permissions issue. Due to a logical error in the file caching layer an authenticated adversary is able to create empty folders inside a shared folder. Note that this only affects folders and files that the adversary has at least read-only permissions for.

Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 sufre de una creación de carpetas en carpetas de sólo lectura a pesar del problema de permisos que faltan. Debido a un error lógico en la capa de caché de archivos, un adversario autenticado puede crear carpetas vacías dentro de una carpeta compartida. Tenga en cuenta que esto sólo afecta a carpetas y archivos que el adversario tiene al menos permisos de sólo lectura.
