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. (Copy of the Vendor Homepage: http://www.avfirewalls.com/FortiManager-Series.asp ) 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. Vulnerability Disclosure Timeline: ================================== 2016-01-25: Researcher Notification & Coordination (Benjamin Kunz Mejri - Evolution Security GmbH) 2016-01-26: Vendor Notification (FortiGuard Security Team) 2016-02-08: Vendor Response/Feedback (FortiGuard Security Team) 2016-05-17: Vendor Fix/Patch #1 (Fortinet Service Developer Team) 2016-07-28: Vendor Fix/Patch #2 (Fortinet Service Developer Team) 2016-08-02: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Fortinet Product: FortiManager - Appliance (Web-Application) 200D, 300D, 1000D, 3900E, 4000E, Virtual Appliances Versio Fortinet Product: FortiManager - Appliance (Web-Application) Legacy - 100, 100C, 400A, 400B, 400C, 1000C, 3000C & 4000 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.

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!
