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 on 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 on 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!
