The researchers believe it affects all VPN applications when they’re connected to a hostile network and that there are no ways to prevent such attacks except when the user’s VPN runs on Linux or Android.
Once again, Linux with a win!
Any vpn solution that uses a TCP/IP shim in full tunnel mode will ignore option 121 or any other routing options (static routes, etc). Most corporate VPNs like Global Protect/Cisco Any Connect, Appgate, etc will enforce full-tunnel. Any user who is using a VPN for privacy reasons should also use a full tunnel as well especially when connecting to an untrusted networks.
Dang option 121.
I told him 120 options was enough, but he just had to keep adding options.
120 options should be enough for anyone.
119 is too few and 121 is too many.

Why doesn’t my internet look like that stock image tunnel of 1 and 0?
How did nobody discover this sooner if it is a common network option? This seems like it should have been well known to professionals. Who dropped the ball?
So basically don’t be stupid when on a network you don’t control. I mean I would think that would be common sense by now. Just because you’re on a VPN doesn’t mean that the local network doesn’t have some semblance of capabilities.
And maybe I read it wrong, but perhaps don’t use DHCP on a network you don’t control. Wouldn’t that wholly mitigate this?
I get that this is concerning for people who don’t know any better. But I don’t think it’s as devastating as the title makes it sound.
