~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
URVE is a system for reserving rooms which also provides a web interface
with event scheduler.
The manufacturer describes the product as follows (see [1] and [2]):
'Booking rooms on touchscreen and easy integration with MS Exchange,
Lotus, Office 365, Google Calendar and other systems.
Great looking schedules right at the door.
Fight conference room theft with our 10" touchscreen wall-mounted
panel.'
'Manage displays, edit playlists and HTML5 content easily.
Our server can be installed on any Windows and works smoothly from
web browser.'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
The password of the user account which is used for the connection of
the MS Office 365 Integration Service is stored as plaintext in
configuration files, as well as in the database.
The following files contain the password in plaintext:
Profiles/urve/files/sql_db.backup
Server/data/pg_wal/000000010000000A000000DD
Server/data/base/16384/18617
Server/data/base/17202/8708746
This causes the password to be displayed as plaintext in the HTML code.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
The path
/urve/roomsreservationimport/roomsreservationimport/update-HTML5?id=<id>
contains the tag with the cleartext password:
<input id="roomsreservationimport_password" [...] value="clearTextPassword">
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Solution:
The password should be stored as cryptographic hash value.
