Medium


Details:
========
Multiple persistent Input Validation vulnerabilities are detected on Barracudas 
Spam & Virus Web Firewall 600. 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): 
                                                                [+] Trace route 
Device - Troubleshooting
                                                                [+] LDAP 
Configuration - LDAP Username

Affected Version(s):
                                                                [+] Barracuda 
Spam & Virus Firewall 600

Affected Firmware(s):
                                                                [+] Firmware 
v4.0.1.009 & older versions

Picture(s):
                                                                ../ldap.png


Proof of Concept:
=================
The persistent vulnerabilities can be exploited by local low privileged user 
accounts with low required user inter action or 
by remote attackers with high required user inter action.

Manually Steps ...
1. Login to the Barracuda Application
2. Open the vulnerable area were the persistent vulnerability is located
3. Include/Insert your own script code or poc and save/execute the content to 
inject
4. View the injected results which were stored on application side. The code is 
getting executed in the  output section

PoC: 
%3E%3E%22%3C%69%66%72%61%6D%65%20%73%72%63%3D%68%74%74%70%3A%2F%2F%77%77%77%2
E%76%75%6C%6E%65%72%61%62%69%6C%69%74%79%2D%6C%61%62%2E%63%6F%6D%20%77%69%64%
74%68%3D%36%30%30%20%68%65%69%67%68%74%3D%36%30%30%3E


Solution:
=========
2011-12-22:     Vendor Fix/Patch


Risk:
=====
The security risk of the persistent vulnerabilities are estimated as medium(+).
