CVE-2016-6658 Incomplete fix for Credential Vulnerability for Custom Buildpacks




Cloud Foundry Foundation

Versions Affected

  • cf-release versions prior to 245


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.
