medium Nessus Plugin ID 209735

Language:

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of FortiWeb installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-21-156 advisory.

 - A relative path traversal in FortiWeb versions 6.4.1, 6.4.0, and 6.3.0 through 6.3.15 may allow an authenticated attacker to retrieve arbitrary files from the underlying filesystem via specially crafted web requests. (CVE-2021-41026)

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

Solution

Please upgrade to FortiWeb version 6.3.16/6.4.2/7.0.0 or later.
