Severity:  
=========  
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

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:

Solution:  
=========  
2011-12-22: Vendor Fix/Patch  
  
  
Risk:  
=====  
The security risk of the persistent vulnerabilities are estimated as medium(+).
