CVE-2016-6658

• Severity: critical (CVSS 9.6 v3.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.9% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2018-03-29 · updated 2026-06-17
• Weakness: CWE-200

Description

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

• Cloud Foundry Cloud Controller cf-release versions prior to v255: before 245 — fixed in 245
• PCF Elastic Runtime: before 1.6.49; from 1.7.0 before 1.7.31; from 1.8.0 before 1.8.11 — fixed in 1.6.49, 1.7.31, 1.8.11

How to fix

Upgrade to a fixed version: Cloud Foundry Cloud Controller cf-release versions prior to v255 245; PCF Elastic Runtime 1.6.49, 1.7.31, 1.8.11. Check the vendor advisory for mitigations.
