    Based on this website it sounds like the following IPS signatures are what you're looking for:

     

    FortiGuard IPS

    The following IPS signatures were released on March 3-4, 2021 to detect and stop exploits targeting the four vulnerabilities identified in this exploit. All Fortinet customers with an active subscription and current update are already protected.
