CVE-2023-22650Network attack vector

Unauthorized access via stale external-authentication tokens

Published Oct 16, 2024 · Updated Oct 16, 2024

Improper authentication in SUSE Rancher 2.7.0 through 2.7.13 and 2.8.0 through 2.8.4 lets remote authenticated users retain access. Rancher leaves external-authentication users active and their tokens usable after the configured provider deletes, disables, or revokes their accounts. An external authentication provider must be enabled; built-in user management is unaffected, while stale privileges remain usable in Rancher.
