Product & Service Introduction:  
===============================  
FortiManager appliances allow you to centrally manage any number of  
Fortinet devices, from several to thousands, including FortiGate®,  
FortiWiFi™,  
FortiCarrier™, FortiMail™ and FortiAnalyzer™ appliances and virtual  
appliances, as well as FortiClient™ endpoint security agents. You can  
further  
simplify control and management of large deployments by grouping devices  
and agents into administrative domains (ADOMs).  
  
The FortiManager family of management appliances provides centralized  
policy-based provisioning, device configuration, and update management for  
FortiGate, FortiWiFi, and FortiMail appliances, and FortiClient  
end-point security agents, plus end-to-end network monitoring and device  
control.  
FortiManager delivers a lower TCO for Fortinet implementations by  
minimizing both initial deployment costs and ongoing operating expenses.  
Control  
administrative access and simplify policy deployment using role-based  
administration to define user privileges for specific management domains  
and  
functions, and aggregating collections of Fortinet appliances and agents  
into independent management domains. In addition, by locally hosting  
security  
content updates for managed devices and agents, FortiManager appliances  
minimize Web filtering rating request response time and maximize network  
protection.

Technical Details & Description:  
================================  
A persistent input validation web vulnerability and filter bypass issue  
has been discovered in the official Fotinet FortiManager and  
FortiAnalyzer appliance product series.  
The application-side web vulnerability allows remote attackers to inject  
own malicious script codes to the application-side of the affected  
modules context.  
  
The vulnerability is located in the `filename` value of the ` Layout  
Header [Header Image]` module. Remote attackers with low privileged  
web-application user accounts  
are able to inject own malicious script codes to the application-side of  
the affected ` Advanced Settings - Advanced Settings - Layout Header`  
module. The request method  
to inject is POST and the issue is located on the application-side of  
the fortimanager/fortianalyzer appliance web-application.  
  
The security risk of the client-side cross site scripting web  
vulnerability is estimated as medium with a cvss (common vulnerability  
scoring system) count of 3.7.  
Exploitation of the application-side web vulnerability requires no  
privileged web-application user account and low or medium user  
interaction. Successful exploitation  
of the vulnerability results in persistent phishing, session hijacking,  
persistent external redirect to malicious sources and application-side  
manipulation of affected  
or connected web module context.

Proof of Concept (PoC):  
=======================  
The persistent input validation web vulnerability can be exploited by  
local low privileged web-application user accounts and low user  
interaction (click).  
For security demonstration or to reproduce the vulnerability follow the  
provided information and steps below to continue.  
  
Manual steps to reproduce the vulnerability ...  
1. Login to the Fortinet FortiManager appliance web-application  
2. Open the following module Reports > Reports > Client Reputation >  
Advanced Settings > Advanced Settings > Layout Header  
3. Scroll to the layout header section  
4. Start a session tamper to intercept the http protocol communication  
5. Choose a random file and perform the upload  
6. Change with the live session tamper the filename value of the logo to  
a script code payload  
7. Wait since the upload has been performed and click next to the upload  
input field  
8. The script code executes were the filename is normally visible next  
to the upload via submit  
9. Successful reproduce of the vulnerability!  
  
Note: There could be other sections that are affected after the inject  
were the logo image is displayed finally!
