# 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,

Serviio PRO 1.8 DLNA Media Streaming Server Local Privilege Escalation
|
||||
|
||||
|
||||
Vendor: Petr Nejedly | Six Lines Ltd
|
||||
Product web page: http://www.serviio.org
|
||||
Affected version: 1.8.0.0 PRO
|
||||
|
||||
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 application suffers from an unquoted search path issue impacting the service
|
||||
'Serviio' for Windows deployed as part of Serviio DLNA server solution. This could potentially
|
||||
allow an authorized but non-privileged local user to execute arbitrary code with elevated
|
||||
privileges on the system. A successful attempt would require the local user to be able to
|
||||
insert their code in the system root path undetected by the OS or other security applications
|
||||
where it could potentially be executed during application startup or reboot. If successful, the
|
||||
local user’s code would execute with the elevated privileges of the application.
|
||||
|
||||
Serviio also suffers from improper permissions which can be used by a simple authenticated user
|
||||
that can change the executable file with a binary of choice. The vulnerability exist due to the
|
||||
improper permissions, with the 'F' flag (Full) for 'Users' group, for the Serviio directory and
|
||||
its sub-directories.
|
||||

||||

|

#
|

# Desc: The version of Serviio installed on the remote Windows host is affected by

# an unauthenticated remote code execution vulnerability due to improper access control

# enforcement of the Configuration REST API and unsanitized input when FFMPEGWrapper

# calls cmd.exe to execute system commands. A remote attacker can exploit this with a
