Discovery Status:
=================
Published


Exploitation Technique:
=======================
Remote


Severity Level:
===============
Medium


Technical Details & Description:
================================
1.1
A non-persistent Input Validation vulnerability is detected on Barracudas IM-Firewall 620.
Attackers can form malicious client-side requests to hijack customer/admin sessions.
Successful exploitation requires user inter action & can lead to information disclosure, session 
hijacking and access to servers in the intranet.

Vulnerable Module(s):
						[+] SMTP TEST - Email

1.2
A persistent Input Validation vulnerability is detected on Barracudas IM-Firewall 620. Local low privileged user account can
implement/inject malicious persistent script code. When exploited by an authenticated user, the identified vulnerabilities 
can lead to information disclosure, access to intranet available servers, manipulated persistent content.

Vulnerable Module(s):
						[+] Logs/Reports - User Reports

Pictures:
						../imfw660_2.png


Proof of Concept (PoC):
=======================
The vulnerabilities can be exploited by local low privileged user accounts or remote via high user inter action. For demonstration or reproduce ...


1.1 - Client-side:
http://im.xxx.com/cgi-mod/smtp_test.cgi?locale=en_US&host=undefined&port=undefined&domain=undefined&email=>"<INCLUDE SCRIPT-CODE HERE!!!>
&hostname=undefined&default_domain=undefined&user=guest&password=c6aea12bd7f5a5096d7124a845b8897c&et=1259889097


1.2 - Application-side:

Vulnerable Module(s):	
								[+] User Report Module


Manually reproduce ...
1. Login
2. Switch to the vulnerable logs/reports module of the application
3. Switch to the User Reports & include script code 
4. Enjoy the persistent output results


Security Risk:
==============
1.1
The security risk of the non-persistent vulnerability is estimated as low  because of high required user inter action.

1.2
The security risk of the persistent vulnerability is estimated as high(-) because of low required user interaction.
