Thanks for sharing.

You are welcome

Note: All new deployments of Veeam Backup & Replication version 11 and 10 installed using the ISO images dated 20220302 or later are not vulnerable.

It’s important to note that if you are using v11 before v11a you need to upgrade to v11a to solve the vulnerability.

Just thought I’d add this in, but no doubt everyone is already doing it. Make sure you have a backup of your Veeam config before you upgrade, just in case.
