This is kinda overblown. The exploit requires an "authenticated" user that does not already have an admin privilage. Seems to me like that is a very small population of possible examples.
The stupid Veeam software doesn't even like to launch unless you run it as admin, so I wonder how many people have even built setups for non system-admin users to be able to do things with it.
my veeam is on a vlan that can't even access the internet and isn't connected to the domain, so anyone that can log into Windows on it is gonna have elevated privilages.
