Product & Service Introduction:
===============================
The proven SonicOS architecture is at the core of every Dell™ SonicWALL™
firewall from the SuperMassive™ E10800 to the TZ 100.
SonicOS uses deep packet inspection technology in combination with multi-core
specialized security microprocessors to deliver
application intelligence, control, and real-time visualization, intrusion
prevention, high-speed virtual private networking (VPN)
technology and other robust security features.

Technical Details & Description:
================================
Multiple client-side cross site scripting web vulnerabilities has been
discovered in the official SonicWall SonicOS v6.x and v7.5.0.12.
The security vulnerability allows remote attackers to manipulate client-side
application to browser requests to compromise session information.
The vulnerability is located in the `searchSpoof and searchSpoofIpDet` values
of the `Network > MAC-IP Anti-spoof` module. Remote attackers are able to
inject malicious script codes to client-side application requests. Remote
attackers are able to prepare special crafted weblinks to execute client-side
script code that compromises the sonicos application user/admin session data.
The execution of the script code occurs in the mac-ip anti spoof module.
The attack vector of the vulnerability is located on the client-side of the
online-service and the request method to inject or execute the code is GET.
The security risk of the non-persistent cross site vulnerability is estimated
as medium with a cvss (common vulnerability scoring system) count of 3.0.
Exploitation of the non-persistent cross site scripting web vulnerability
requires no privileged web application user account and low user interaction.
Successful exploitation of the vulnerability results in session hijacking,
non-persistent phishing, non-persistent external redirects, non-persistent load
of malicious script codes or non-persistent web module context manipulation.
Request Method(s):
[+] GET
Vulnerable Module(s):
[+] Network > MAC-IP Anti-spoof
Vulnerable File(s):
[+] macIpSpoofView.html
Vulnerable Parameter(s):
[+] searchSpoof
[+] searchSpoofIpDet
During the client security tests the research team noticed that the official vm
version and the all appliance models are affected by the security issue.
The following versions and models of the sonicwall appliance web-application
are affected by the remote cross site scripting vulnerability.
Affected Model(s):
[+] (CASS) Anti Spam - UTM Integrated Anti-Spam
[+] (CASS) Anti Spam - Enhanced Comprehensive
Anti-spam
[+] (CASS) Anti Spam - Email Security
Affected Version(s):
[+] SonicOS v7.5.0.12
[+] SonicOS v6.x
Proof of Concept (PoC):
=======================
The client-side cross site scripting vulnerability can be exploited by remote
attackers without privileged application user account and
with low or medium user interaction. For security demonstration or to reproduce
the security vulnerability follow the provided information
and steps below to continue.

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure parse and encode of the vulnerable
searchSpoof and searchSpoofIpDet parameters.
Restrict the input of the values and encode the output context of the
macipspoofview.html to prevent client-side or application-side script code
injection attacks.
Security Risk:
==============
The security risk of the cross site scripting web vulnerability in the
macipspoofview.html file is estimated as medium. (CVSS 3.0)
