CVE-2020-14380Network attack vector

Account takeover via cross-source username collision

Published Jun 2, 2021 · Updated Aug 4, 2024

Improper authentication in Red Hat Satellite 6.8 allows remote authenticated users to assume existing local accounts through external SSO. The external-authentication account lookup accepts an external identity when its username matches an internal user, binding the session to that local account. Exploitation requires valid Apache SSO, Kerberos, or OpenID Connect credentials, a colliding local username, and automatic user creation enabled, granting the local account's privileges.
