Product & Service Introduction:
===============================
The FortiAnalyzer family of logging, analyzing, and reporting appliances securely aggregate log data from Fortinet devices and other 
syslog-compatible devices. Using a comprehensive suite of easily-customized reports, users can filter and review records, including 
traffic, event, virus, attack, Web content, and email data, mining the data to determine your security stance and assure regulatory 
compliance. FortiAnalyzer also provides advanced security management functions such as quarantined file archiving, event correlation, 
vulnerability assessments, traffic analysis, and archiving of email, Web access, instant messaging and file transfer content.

Secure data aggregation from multiple FortiGate and FortiMail security appliances provides network-wide visibility.
Over 300 customizable reports help monitor and maintain acceptable use policies, identify attack patterns, and comply with governmental ...
Network capacity and utilization data reporting enables network administrators to plan and manage networks more efficiently.
Fully integrated with FortiManager appliances for a single point of command, control, analysis, and reporting.
FortiGuard subscription services deliver dynamic updates to vulnerability management functionality through intelligence gathered by Fortinet s ...
Advanced features such as event correlation, forensic analysis, and vulnerability assessment provide essential tools for in-depth protection of 
complex networks. Up to 6 TB of log data capacity and choice of RAID levels allow administrators to balance capacity and data assurance to 
match organizational needs.

Vulnerability Disclosure Timeline:
==================================
2011-09-12:	Public or Non-Public Disclosure


Discovery Status:
=================
Published


Affected Product(s):
====================

Exploitation Technique:
=======================
Remote


Severity Level:
===============
Medium


Technical Details & Description:
================================
1.1
An input validation vulnerabilities(persistent) is detected on the FortAnalyzer Appliance Series. Attackers can include persistent 
malicious script codes to manipulate specific customer requests & modules. The vulnerability allows an attacker also to hijack customer 
sessions with persistent script code attacks.

Vulnerable Module(s): (Persistent)
								[+] Filter Value on Log Access IPS Attack Listing - Category Preview (Persistent)


1.2
An input validation vulnerabilities(non-persistent) is detected on the FortAnalyzer Appliance Series. Attackers can execute with 
high user inter action non-persistent script codes on client-side. The vulnerability allows an attacker also to form manipulated cross 
site requests to hijack admin/customer sessions on client-side.

Vulnerable Modules: (Non-Persistent)
								[+] Devices => Edit Device Group (Non-Persistent)

Security Risk:
==============
The security risk of the persistent vulnerability is estimated as medium(+).
The security risk of the non-persistent vulnerability is estimated as low because of high required user inter action.
