CVE-2018-1195
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
