Cloud Foundry

This disclosure regards a vulnerability related to UAA refresh tokens and external identity providers.Assuming that an external identity provider is linked to the UAA, a refresh token is issued to a client on behalf of a user from that identity provider, the administrator of the UAA deactivates the identity provider from the UAA. It is expected that the UAA would reject a refresh token during a refresh token grant, but it does not (hence the vulnerability). It will continue to issue access tokens to request presenting such refresh tokens, as if the identity provider was still active. As a result, clients with refresh tokens issued through the deactivated identity provider would still have access to Cloud Foundry resources until their refresh token expires (which defaults to 30 days).

In Cloud Foundry Foundation CAPI-release versions after v1.6.0 and prior to v1.38.0 and cf-release versions after v244 and prior to v270, there is an incomplete fix for CVE-2017-8035. If you took steps to remediate CVE-2017-8035 you should also upgrade to fix this CVE. A carefully crafted CAPI request from a Space Developer can allow them to gain access to files on the Cloud Controller VM for that installation, aka an Information Leak / Disclosure.

The Cloud Controller and Router in Cloud Foundry (CAPI-release capi versions prior to v1.32.0, Routing-release versions prior to v0.159.0, CF-release versions prior to v267) do not validate the issuer on JSON Web Tokens (JWTs) from UAA. With certain multi-zone UAA configurations, zone administrators are able to escalate their privileges.
