It looks like two different holes, one a back door for unauthorized
console login and one to somehow leak VPN encryption keys.  There are
hints that that latter involved tinkering with certain constants in
the crypto (https://twitter.com/matthew_d_green/status/677871004354371584);
that would squarely point the finger at some government's intelligence
agency.

I don't know who did it, but neither 'bug' nor 'developer debugging
code' sounds plausible here.
