Doc Text:	It was discovered that Director's NeutronMetadataProxySharedSecret parameter remained specified at the default value of 'unset'. This value is used by OpenStack Networking to sign instance headers; if unchanged, an attacker knowing the shared secret could use this flaw to spoof OpenStack Networking metadata requests.

Description Summer Long 2015-10-16 02:40:41 UTC

Steven Hardy reports: Currently we don't set the NeutronMetadataProxySharedSecret, (which according to the description in the neutron docs exists to prevent spoofing) - thus is remains at it's bad default value of "unset".

I assume this has the potential for security impact given that if it's predictable I guess spoofing metadata requests then becomes possible, but not being a Neutron expert I'm not sure of how serious an issue this may be.
