Fortinet FortiOS 7.0.x <= 7.0.5 / 6.4.x <= 6.4.9 XSS (FG-IR-21-057)

medium Nessus Plugin ID 163252

Synopsis

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

Description

The remote host is running a version of FortiOS that is 7.0.x through 7.0.5 or 6.4.x through 6.4.9. It is, therefore, affected by a cross-site scripting (XSS) vulnerability due to improper neutralization of input during web page generation. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

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

Solution

Update FortiOS to version 7.0.6, 7.2.0, or later.
