Descriptions

OpenStack Object Storage (Swift) before 2.3.0, when allow_version is configured, allows remote authenticated users to delete the latest version of an object by leveraging listing access to the x-versions-location container.

OpenStack Object Storage (Swift) anterior a 2.3.0, cuando allow_version está configurado, permite a usuarios remotos autenticados eliminar la última versión de un objeto mediante el aprovechamiento del acceso listado al contenedor de la localización de versiones x.

A flaw was found in OpenStack Object Storage that could allow an authenticated user to delete the most recent version of a versioned object regardless of ownership. To exploit this flaw, an attacker must know the name of the object and have listing access to the x-versions-location container.
