SSH Public keys regenerate
« on: July 17, 2015, 12:02:10 PM »
I have a couple of ERS5698TFD switches with SW:v6.2.5.027

yes the code is a little bit old and will be updating it soon.

I had an internal Pen test and they highlighted that the switches are accepting a publicly known static SSH private key for authentication, which allows access to the switches, the switches have a close to default setup.

Anyone got any ideas how I can Remove the vulnerable public keys from the switches, or would "ssh dsa-host-key" regenerate the keys?

Any pointers would be good thanks in advance.

The ssh dsa-host-key command should generate a new host key. If there is a bug how the key is generated I would suggest that you need to do an SW update.
