Fortinet FortiOS 5.2.x < 5.2.11 srcintf XSS (FG-IR-17-017)

medium Nessus Plugin ID 99969

Language:

Synopsis

The remote host is affected by a cross-site scripting vulnerability.

Description

The version of Fortinet FortiOS running on the remote FortiGate device is 5.2.x prior to 5.2.11. It is, therefore, affected by a cross-site scripting (XSS) vulnerability when creating firewall policies due to improper validation of input related to srcintf before returning it to users. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

Solution

Upgrade to Fortinet FortiOS version 5.2.11 or later.
