Fortinet software Remote Code Execution and Denial of Service vulnerability

A vulnerability has been discovered that affects FortiOS and FortiProxy’s administrative interface. FortiOS is used on FortiGate, and FortiWifi devices.

This vulnerability (CVE-2023-25610) allows an attacker to run unauthorised commands remotely on some affected systems.

It also allows an attacker to remotely crash affected devices, making them unavailable.

What to look for

How to tell if you're at risk

The vulnerable versions are:

  • FortiOS version 7.2.0 through 7.2.3
  • FortiOS version 7.0.0 through 7.0.9
