Medium Nessus Plugin ID 104657


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


The version of Fortinet FortiOS running on the remote device is 5.2.x prior to 5.2.12, 5.4.x prior to 5.4.6, or 5.6.x prior to 5.6.1. It is, therefore, affected by a flaw in the web proxy disclaimer response page input validation that allows a reflected cross-site scripting (XSS) attack.


Upgrade to Fortinet FortiOS version 5.2.12 / 5.4.6 / 5.6.1 or later.
