Product & Service Introduction:
===============================
The proven SonicOS architecture is at the core of every Dellâ„¢ SonicWALLâ„¢ firewall \
from the SuperMassiveâ„¢ 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)
