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):

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):

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(-).
