Fortinet FortiADC contains a cross-site scripting vulnerability

Overview

Fortinet FortiADC 3.2, and possibly earlier versions, contains a cross-site scripting vulnerability. (CWE-79)

Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Fortinet FortiADC 3.2, and possibly earlier versions, contains a cross-site scripting vulnerability. The "locale" parameter in the "/FortiADC/gui_partA/?locale=en" page is vulnerable to a reflected cross-site scripting attack.

Impact

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user's browser session.

Solution

We are currently unaware of a practical solution to this problem.

Restrict access As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the FortiADC interface using stolen credentials from a blocked network location.
