Fortinet FortiOS 5.x < 5.4.8 / 5.6.x < 5.6.3 HTTP Host Header XSS(FG-IR-17-262)

medium Nessus Plugin ID 106583

Language:

Synopsis

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

Description

The version of Fortinet FortiOS running on the remote device is 5.x prior to 5.4.8, or 5.6.x prior to 5.6.3. It is, therefore, affected by a Cross-site Scripting (XSS) vulnerability that would allow an attacker to inject an HTML request through the 'Host' headers of the web proxy disclaimer page.

Note that Nessus has not checked for the workaround.

Solution

Upgrade to Fortinet FortiOS version 5.4.8 / 5.6.3 or later.
