Vulnerability Name:

CVE-2018-1195 (CCN-140519)

Assigned:2017-12-06
Published:2018-03-05
Updated:2022-08-29
Summary:In Cloud Controller versions prior to 1.46.0, cf-deployment versions prior to 1.3.0, and cf-release versions prior to 283, Cloud Controller accepts refresh tokens for authentication where access tokens are expected. This exposes a vulnerability where a refresh token that would otherwise be insufficient to obtain an access token, either due to lack of client credentials or revocation, would allow authentication.
