OpenStack Compute (Nova) Exposure of Sensitive Information to an Unauthorized Actor vulnerability
Quick fix
PYSEC-2026-884 — nova: upgrade to the fixed version with the command below.
pip install --upgrade 'nova>=2013.2.4'Details
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.
