Descriptions

The virtual filesystem in ownCloud Server before 6.0.9, 7.0.x before 7.0.7, and 8.0.x before 8.0.5 does not consider that NULL is a valid getPath return value, which allows remote authenticated users to bypass intended access restrictions and gain access to users files via a sharing link to a file with a deleted parent folder.

El sistema de archivos en ownCloud Server en versiones anteriores a 6.0.9, 7.0.x en versiones anteriores a 7.0.7 y 8.0.x en versiones anteriores a 8.0.5 no considera que NULL es un valor de retorno getPath válido, lo que permite a usuarios remotos autenticados eludir las restricciones destinadas al acceso y ganar acceso a los archivos de usuarios a través de un enlace compartido a un archivo con una carpeta principal eliminada.

Multiple vulnerabilities were discovered in ownCloud, a cloud storage web service for files, music, contacts, calendars and many more. These flaws may lead to the execution of arbitrary code, authorization bypass, information disclosure, cross-site scripting or denial of service.
