Common Vulnerability Scoring System:

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.

Abstract Advisory Information:
==============================
The Vulnerability Laboratory Core Research Team discovered a persistent and non-persistent web validation vulnerability in 
the official Fotinet FortiManager appliance product series. The issue affects the web-application of the appliance series and is 
present in the following fortimanager models - 200D,  300D, 1000D, 3900E, 4000E, Virtual Appliances Version and FortiMoM-VM. 
The Fortimanager legacy models 100, 100C, 400A, 400B, 400C, 1000C, 3000C and 4000D are affected as well by the vulnerability.

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


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


Technical Details & Description:
================================
A persistent and non-persistent input validation web vulnerability has been discovered in the official Fotinet FortiManager appliance product series.
The vulnerability allows privileged guest user accounts and restricted user accounts to inject own malicious script codes on the application-side or 
client-side of the fortimanager appliance web-application series.

The vulnerability is located in the `add Tags` input field of the `Firewall Objects - Address - Tags` module. The request method to inject is POST to 
GET and the attack vector is located on the application-side of the appliance web-application. Remote attackers are able to inject own malicious script 
codes to the add tag input field. After processing to add, the code bypasses the regular web filter of the appliance web-application and executes finally 
in the applied tags module above of the basic input. The vulnerability can be exploited by guest appliance user accounts with restricted access. The 
vulnerability first executes with client-side attack vector and becomes persistent with the save procedure by return.

The security risk of the application-side and client-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.8. 
Exploitation of the application-side web vulnerability requires a low privileged guest web-application user account and low 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 and non-persistent cross site scripting web vulnerability can be exploited by remote attackers with low privileged web-application user account and low user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.

Manual steps to reproduce the vulnerability as guest user with restricted access privileges ...
1. Login to the fortimanager appliance web-application as guest user
2. Open the following section that is not restricted to guests mainly (Firewall Objects > Address )
3. Now, switch to the Tags section and click to the non-restricted button [Add Tags]
4. Add in the `Add Tags` and inject to the input field your test payload to approve the validation
Note: (Payload) "><"<img src="x">%20%20>"<iframe src=a>%20<iframe>
5. The script code execution occrs in the applied tags listing.
6. Successful reproduce of the vulnerability!
