Right now there is no fix. No version to upgrade to.

The vulnerabilities are usually for the device itself.

So management interface is affected. 

But you can use self-ip also to manage the device. And that go through tmm.

look at the self-ip port-lockdown option. if is set to default it means it allows a bunch of ports, including https.

you might want to choose none and use only management interface for administrative stuff.
