Hi All,
Please would you mind telling us exactly which products and version are
concerned by this issue ?
We contact Fortinet and it seems they are not informed about it and there is no
patch available at this time.

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.

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