NPS- MFA loop after Windows Server update

ShadowNif — Mon, 14 Oct 2024 14:55:24 GMT

Hello,

I have patched my Windows server 2019 to the latest MS update. All of a sudden, my MFA stuck in a loop.

I was keep getting the Approval on my Phone for the VPN and each time i approve, it comes again and i cannot login.

On the FW Side it shows

"RADIUS servers not responding"

Is there any known issue for this ? Because after I restore it from snapshot it worked fine.

The issue is related to Blast RADIUS (CVE-2024-3596).
See: https://support.checkpoint.com/results/sk/sk182516
As Remote Access isn't yet fixed for this issue, you'll probably have to apply the solution from: https://support.checkpoint.com/results/sk/sk42184
