CVE-2019-17134

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
