Fortinet Fortigate XSS (FG-IR-22-224)

medium Nessus Plugin ID 174223

Language:

Synopsis

Remote host is affected by a xss vulnerability.

Description

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-22-224 advisory. An improper neutralization of input during web page generation vulnerability in FortiOS may allow a remote, unauthenticated attacker to launch a cross site scripting (XSS) attack via the redir parameter of the URL seen when the Sign in with FortiCloud button is clicked.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Fortigate version 7.0.8 / 7.2.4 or later.
