Authentication Bypass Redhat Suse

Description

An issue was discovered in OpenStack keystonemiddleware 10.5 through 10.7 before 10.7.2, 10.8 and 10.9 before 10.9.1, and 10.10 through 10.12 before 10.12.1. The external_oauth2_token middleware fails to sanitize incoming authentication headers before processing OAuth 2.0 tokens. By sending forged identity headers such as X-Is-Admin-Project, X-Roles, or X-User-Id, an authenticated attacker may escalate privileges or impersonate other users. All deployments using the external_oauth2_token middleware are affected.

Analysis

OpenStack keystonemiddleware 10.5 through 10.9 has an authentication spoofing vulnerability (CVSS 9.9) allowing attackers to bypass Keystone token validation and access any OpenStack service as any user.
