medium Nessus Plugin ID 214073

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-23-458 advisory.

 - A stack-based buffer overflow in Fortinet FortiWeb versions 7.2.0 through 7.2.7, and 7.4.0 through 7.4.1 may allow a privileged user to execute arbitrary code via specially crafted CLI commands, provided the user is able to evade FortiWeb stack protections. (CVE-2024-21758)

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 FortiWeb version 7.2.8 / 7.4.2 or later.
