CVE-2016-6658: Cloudfoundry Cf-Release

Critical severity, CVSS 9.6. EPSS: 0.9% chance of exploitation in the next 30 days.

Applications in cf-release before 245 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.

Affected products

• Cloudfoundry Cf-Release: before 245 (fixed in 245)
• Pivotal Software Cloud Foundry Elastic Runtime: before 1.6.49 (fixed in 1.6.49); from 1.7.0, before 1.7.31 (fixed in 1.7.31); from 1.8.0, before 1.8.11 (fixed in 1.8.11)
