api/metadata/handler.py in OpenStack Compute (Nova) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instance ID signatures via a brute-force attack that relies on timing differences in responses to instance metadata requests.

Security readout for executives and security teams

This flaw affected older OpenStack Nova metadata handling when Nova proxied metadata requests through Neutron. A timing difference could make secret instance ID signatures easier to guess. For organizations still running these old OpenStack branches, the business risk is unauthorized metadata access paths becoming easier to abuse. Exposure is most likely in legacy OpenStack Compute deployments using affected Nova versions with metadata requests proxied through Neutron. The supplied sources do not identify affected downstream distributions, hosted clouds, or supported package backports. Prioritize this if legacy OpenStack infrastructure remains in service, especially multi-tenant clouds. Modern or fully patched deployments are unlikely to require emergency action based on the provided evidence. Mitigation focus: Upgrade Nova to 2013.2.4, 2014.1.2, Juno-2, or later as applicable.; Check distribution vendor advisories for backported Nova fixes.; Confirm Neutron metadata proxy deployments received the patched Nova package..
