CVE-2016-9882 Cloudfoundry CVE debrief

Who should care

Cloud Foundry operators, platform SREs, security teams, and anyone who manages log storage, forwarding, or access controls for Cloud Controller and related system logs. Teams that rely on service brokers for app services should also care, because broker-returned credentials may have been exposed in log pipelines.

Technical summary

The NVD record maps the issue to CWE-532 (Insertion of Sensitive Information into Log File). The vulnerable versions are cf-release versions prior to v250 and CAPI-release versions prior to v1.12.0. The problem is not a code execution flaw; it is a credential exposure risk caused by logging sensitive broker response data. If logs are retained, replicated, or centrally aggregated, the exposure surface includes every authorized or compromised log consumer.

Defensive priority

High. This is a network-reachable, no-authentication confidentiality issue with CVSS 3.1 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Prioritize remediation if Cloud Foundry logs are accessible to broader operational teams, shipped off-host, or retained for long periods.

Recommended defensive actions

• Upgrade cf-release to v250 or later and CAPI-release to v1.12.0 or later, per the vendor guidance.
• Review Cloud Controller and aggregated logs for any credentials or secrets that may have been recorded before remediation.
• Rotate any service broker credentials or other secrets that may have been exposed in logs.
• Restrict access to log files, log aggregation systems, and syslog pipelines to the minimum required personnel and services.
• Apply log redaction or sensitive-field filtering controls where available, and validate that broker responses are no longer logged.
• Shorten log retention where appropriate and ensure backups or archives containing affected logs are handled as sensitive data.

Evidence notes

The supplied NVD record states that Cloud Foundry logs credentials returned from service brokers in Cloud Controller system component logs, and that those logs are written to disk and often sent to a log aggregator via syslog. The same record identifies affected versions as cf-release prior to v250 and CAPI-release prior to v1.12.0, assigns CWE-532, and provides a CVSS v3.1 vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N.
