Doc Type: If docs needed, set a value
Doc Text:
A certificate-validation error has been found in Octavia's amphora-agent, where an attacker with management-network access could bypass an amphora's client-certificate based authentication. Because the agent's HTTP server (gunicorn) had 'cert_reqs' set to 'True' instead of 'ssl.CERT_REQUIRED', information could be retrieved or configuration updated without a client certificate.

Description Summer Long 2019-10-14 04:28:50 UTC
From NVD via oss-security: 
Amphora Images in OpenStack Octavia >=0.10.0 <2.1.2, >=3.0.0 <3.2.0, >=4.0.0 <4.1.0 allows anyone with access to the management network to bypass client-certificate based authentication and retrieve information or issue configuration commands via simple HTTP requests to the Agent on port https/9443, because the cmd/agent.py gunicorn cert_reqs option is True but is supposed to be ssl.CERT_REQUIRED.
