This CVE addresses an incomplete fix for CVE-2016-6638, a credential vulnerability in the Cloud Controller database.
Original text of CVE-2016-6638: Applications can be configured and pushed with a user-provided custom buildpack using a URL pointing to the buildpack. Although it is not recommended, a user can specify a credential in the URL (basic auth or OAuth) to access the buildpack through the CLI. For example, the user could include a GitHub username and password in the URL to access a private repository. Because the URL to access the buildpack is stored unencrypted, an operator with privileged access to the Cloud Controller database could view these credentials.
OSS users are strongly encouraged to follow one of the mitigations below:
