Synful Knock questions...

Tue Sep 15 18:15:48 UTC 2015

I'm sure most have already seen the CVE from Cisco, and I was just reading
through the documentation from FireEye:

l

Question is that it looks to me like they are over-writing the ospf response
for "show ip ospf timers lsa-group"?
And if that's the case I'm guessing the router would need to have ospf
enabled to be able to see the response?
