Re: Should the OpenStack API re-use the EC2 credentials?


The issue is that _if_ you're also running the EC2 API over non-SSL (which
is supposed to be safe - other than for replay attacks?), then you send the
api_key in the clear (the api_secret remains secret because it's only
'passed' via the one-way-hashed signature.)  However, api_key is currently
the OpenStack 'secret'/'password' (!).  So although we're not exposing the
EC2 api_secret, using the EC2 API could expose a rather important piece of
information for the OpenStack API.

I don't think it's a critical vulnerability (hence it's in public channels),
but I believe it needs to be fixed.

Irrespective of the vulnerability, I think we should still have one set of
user credentials.
