## Overview

An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] affecting FortiOS 7.0.0 through 7.0.16 and FortiProxy 7.2.0 through 7.2.12, 7.0.0 through 7.0.19 may allow a remote unauthenticated attacker with prior knowledge of upstream and downstream devices serial numbers to gain super-admin privileges on the downstream device, if the Security Fabric is enabled, via crafted CSF proxy requests.

## Affected

- `fortiproxy >= 7.0.0, < 7.0.20`
- `fortiproxy >= 7.2.0, < 7.2.13`
- `fortios >= 7.0.0, < 7.0.17`

## Remediation

Upgrade past the affected range:

- `fortiproxy 7.2.13`
- `fortios 7.0.17`
