We have a forti firewall affected by vulnerability FG-IR-22-398.
It is a FortiGate 200B with version 5.2.3 build 670.
We have checked the upgrade path but we cannot select version 5.2.3 as Current FortiOS Version.
In the case that we could upgrade it would have to be to 6.0.16 or above, but I don't know if it will be possible because of the problem with the upgrade path that I mentioned above.
What options do we have?
