SonicWALL Email Security Input Validation Flaw Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1027925
SecurityTracker URL:  http://securitytracker.com/id/1027925
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Dec 28 2012
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 7.4.1.x
Description:   A vulnerability was reported in SonicWALL Email Security. A remote user can conduct cross-site scripting attacks.

The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the SonicWALL Email Security software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

The 'Bereistellunge testen' module in the 'Host Konfiguration > Einstellungen fur CIFS-Bereitstellung' menu is affected.

The vendor was notified on November 20, 2012.

Benjamin Kunz Mejri from Vulnerability Research Laboratory reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the SonicWALL Email Security software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   The vendor has issued a fix (7.4.2).

Details:
========
A persistent input validation vulnerability is detected in the official Dell SonicWall Email Security (7.4.1.7429) Application.
The vulnerability typus allows an attacker to inject own malicious script code in the vulnerable module on application side (persistent).

The vulnerability is located in the Host Konfiguration >  Einstellungen für CIFS-Bereitstellung > section when processing to request via
the `Bereistellunge testen` module the bound vulnerable [Name des freigegebenen Laufwerks] [Benutzer-ID für Remoteanmeldung] [Kennwort für 
Remoteanmeldung] application parameters. The persistent injected script code will be executed directly out of the `system command failed` 
web application exception-handling.

The vulnerability can be exploited with a low (restricted) privileged application user account and low or medium required user interaction.
Successful exploitation of the vulnerability result in persistent session hijacking, persistent phishing, external redirect, external 
malware loads and persistent vulnerable module context manipulation.

Vulnerable Section(s):
				[+] System > Host Konfiguration >  Einstellungen für CIFS-Bereitstellung

Vulnerable Module(s):
				[+] [Bereitstellung testen] - Exception Handling

Vulnerable Parameter(s):
				[+] [Name des freigegebenen Laufwerks] [Benutzer-ID für Remoteanmeldung] [Kennwort für Remoteanmeldung]


Proof of Concept:
=================
The persistent web vulnerabilities can be exploited by remote attackers with low privileged application user account & low required user inter action.
For demonstration or reproduce ...

</div>


Solution:
=========
To patch/fix the persistent web vulnerabilities parse the exception-handling output parameter listing.
Restrict the input fields (parameters) and disallow special chars and obviously forbidden strings.

2012-12-17:	Vendor Fix/Patch (v7.4.2)

Note: The vulnerability has been addressed by sonicwall in december 2012. 
Sonicwall provids all the customers an upgrade/update to version 7.4.2. 




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