Severity

Medium

Vendor

Cloud Foundry Foundation

Versions Affected

• cf-release versions prior to 245
• Please note: this CVE was intended to be fixed in cf-release 241 but it was discovered that the fix was incomplete, which was assigned CVE-2016-6658.

Description

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 repo. Because the URL to access the buildpack is stored unencrypted, an operator with privileged access to the Cloud Controller database could view these credentials.

Mitigation

OSS users are strongly encouraged to follow one of the mitigations below:

• Upgrade to the latest version of cf-release [1]
