Summary

[none]

Details

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 externaloauth2token 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 externaloauth2token middleware are affected.
