Product & Service 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.

Severity Level:
===============
Medium
Technical Details & Description:
================================
Multiple persistent input validation web vulnerabilities has been discovered in
the official Dell SonicWall EMail Security Appliance v7.4.6 Web-Application.
The vulnerability allows remote attackers or low privileged user accounts to
inject own malicious script codes via POST method request to compromise the
application or user session data/information.
The first vulnerability is located in the `filename` value of the
`settings_advanced.html` file. Remote attackers and low privileged application
user accounts
are able to inject own malicious script codes to the application-side of the
`Advanced Settings - Patch hochladen > Patch-Datei` module. Attackers can
manipulate
the file upload POST method request by tampering the session. Next to tampering
the session the attacker exchange the file name with a malicious script code
as payload. In the next step the website reloads the next firmware upgrade page
(wait.html) with the file details. The execute of the injected script code
via POST method request occurs at the location of the listed file name value.
The security risk of the persistent validation web vulnerability is estimated
as medium with a cvss (common vulnerability scoring system) count of 3.5(-).
The second vulnerability is located in the file name value of the
settings_upload_dlicense.html file. Remote attackers and low privileged
application user accounts
are able to inject own malicious script codes to the application-side of the
Lizenz Verwaltung - Lizenzen Upload module. The request method is POST and the
attack
vector is persistent. The execute occurs in the exception context of the
license update page module. The security risk of the persistent validation web
vulnerability is estimated as medium with a cvss (common vulnerability scoring
system) count of 3.0(+).
Exploitation of both vulnerabilities requires to bypass the regular validation
of the web application appliance. To bypass the filter remote attackers can
inject two
payloads with a split in the middle. The validation encodes the first injected
payload and the second after the split executes the code.
Exploitation of the remote web vulnerabilities requires a privileged user
account without user interaction or a remote user with medium to high user
interaction.
Successful exploitation of the persistent web vulnerabilities results in
session hijacking, persistent external redirects, persistent phishing and
persistent
manipulation of vulnerable connected or affected modules.
Request Method:
[+] POST
Vulnerable Module:
[+] Advanced Settings - Patch hochladen >
Patch-Datei (settings_advanced.html)
[+] Lizenz Verwaltung - Lizenzen Upload >
(settings_upload_dlicense.html)
Vulnerable Parameter(s):
[+] file name
Affected Module(s):
[+] Firmware Update - Waiting Page (wait.html)
[+] License Update Page (exception)
Affected Version(s):
[+] 7.4.6
Affected Appliance Model(s):
[+] Dell SonicWall EMail Security Appliance Web
Application - All Models
Proof of Concept (PoC):
=======================
The two persistent input validation web vulnerabilities can be exploited by
remote attackers with low privileged email security application user account
and
low user interaction or without privileged web-application user account on
client-side via POST inject. For security demonstration or to reproduce the
vulnerability follow the provided information and steps below.

Solution - Fix & Patch:
=======================
Both vulnerabilities can be patched by a secure parse and encode of the file
name value in the 2 affected upload POST method requests.
Filter and encode also in the wait.html and license exception the vulnerable
output values even if the input is still parsed.
SonicWall Solution:
============
We recommend existing users of Dell SonicWALL Email Security upgrade to version
7.4.6 to prevent this cross-site script injection from being executed by
unauthorized users.
Email Security 7.4.6 is available for download from www.mysonicwall.com. Users
should log into mySonicWALL and click on Downloads > Download Center in the
navigation panel
in the left-hand navigation, then select “Email Security” in the Software Type
drop down menu.
Security Risk:
==============
The security risk of the persistent and non persistent post inject web
vulnerabilities are estimated as medium.
