Fortinet confirmed that the vulnerability was reported to the company by researchers Charles Fol and Dany Bach from French cybersecurity firm Lexfo. The company also confirmed that the vulnerability has been patched in the latest FortiOS and FortiProxy updates.
However, Fortinet said that it is possible that the vulnerability has already been exploited by attackers in limited cases. The company is working with customers to monitor the situation and is urging customers to upgrade to the latest firmware as soon as possible.
The vulnerability is not believed to be related to the Volt Typhoon campaign, which was detailed by Microsoft in May. The Volt Typhoon campaign is a Chinese state-sponsored operation that has been targeting critical infrastructure organizations in the US territory of Guam. Microsoft said that the hackers exploited internet-exposed Fortinet FortiGuard firewalls for initial access. Fortinet believes that the Volt Typhoon campaign has exploited CVE-2022-40684, a security hole that has been widely exploited for initial access since at least the fall of 2022.
Fortinet customers are advised to upgrade to the latest firmware as soon as possible to protect themselves from this vulnerability. The latest firmware can be found on Fortinet’s website.
In addition to upgrading their firmware, Fortinet customers should also implement other security measures to protect themselves from attack, such as using strong passwords, enabling multi-factor authentication, and keeping their software up to date.
