Subject: Multiple vulnerabilities in IP3 Networks 'NetAccess' NA75 appliance

--------------------
Multiple vulnerabilities have been identified in IP3 Networks
'NetAccess' NA75 appliance. 
--------------------

KPMG recommends that owners of a NetAccess NA75 take steps to ensure the
security of the 
device, and that IP3 Networks is contacted to acquire the new firmware
that includes the 
patches for the issues described. IP3 Networks has requested that
customers contact IP3 
through http://www.ip3.com/supportoverview.htm.

Product:		NA75 and possibly others
Revision:		na-img-4.0.34.bin
Vendor Status: 	notified, verified and patch available from 1 April 2006
Risk:			High
Remote:		Yes
Local:		Yes

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

ISSUE 1: Various SQL injection vulnerabilities in the HTTP user
interface
Due to the absence of user input validation, attackers can embed SQL
commands and queries 
into various HTTP forms. The impact of this is that attackers can login
into the unit by 
specifying username 'admin' and password ' OR "1=1';--. This issue has
been described in
 http://www.securityfocus.com/bid/9858 in 2004, and was reportedly fixed
by IP3 in firmware 
3.1.18b13. However, as can be seen from the above info, we have found
the vulnerability to 
be present in firmware 4.0.34. 

ISSUE 2: Unix command injection vulnerability in command line interface
Due to the absence of user input filtering in the command line
interface, attackers can 
embed Unix commands in certain parameters by passing the commands in the
unix shell 
substitution characters '`'.  

ISSUE 3: No mandatory default password change on first login
The default username and password 'admin'/'admin' do not have to be
changed at first 
login. This greatly increases the chance of the password remaining
'admin' after install. 

ISSUE 4: World readable shadow password file
The shadow password file contains the encrypted passwords for all users
on the system. 
Password crackers can be used on this file to obtain the plaintext
passwords for users.  

ISSUE 5: NetAccess database file world readable and writable
The permission settings on the NetAccess database file allow all unix
users read and 
write access to the file, thereby allowing potentially sensitive
customer information 
to be disclosed.
