CVE-2024-0560

Summary

A vulnerability was found in 3Scale, when used with Keycloak 15 (or RHSSO 7.5.0) and superiors. When the auth_type is use_3scale_oidc_issuer_endpoint, the Token Introspection policy discovers the Token Introspection endpoint from the token_introspection_endpoint field, but the field was removed on RH-SSO 7.5. As a result, the policy doesn't inspect tokens, it determines that all tokens are valid.

Affected Software

Weaknesses

• CWE-280: Improper Handling of Insufficient Permissions or Privileges

Workarounds

Use an alternate auth_type: auth_type: client_id+client_secret. Disabling the policy entirely might be a temporary solution if the alternate {{auth_type is not feasible for some reason. The only purpose the token introspection endpoint serves is for sessions that are revoked in RH SSO before the standard TTL expires via the exp claim.
