Title

Openstack keystone: openstack keystone: authorization bypass via improper ec2 token handling

Summary

A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.

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.
