Since it is remote execution in UEFI, does that mean if you compromised the system you can now use this to install a backdoor in the firmware so wiping and reinstalling won't help?

I think the detailed description of this vulnerability described it as non-persistent in UEFI, but that you could install something that runs before secure boot that would be persistent. I think that's splitting hairs, though - if you've been compromised by someone that has the skills to pull this exploit off, then they can probably chain something else into it now that they've got basically bare-metal access.
