#
# Serviio PRO 1.8 DLNA Media Streaming Server REST API Arbitrary Password Change
#
#
# 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.
#
# Desc: The version of Serviio installed on the remote Windows/Linux host is affected
# by an unauthenticated password modification vulnerability due to improper access
# control enforcement of the Configuration REST API. A remote attacker can exploit this,
# via a specially crafted request, to change the login password for the mediabrowser protected
# page.
#
# 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
