Security readout for executives and security teams
Plain-English summary
CVE-2019-11279 lets a user with existing high privileges in Cloud Foundry UAA request unauthorized scopes and elevate to any scope. If exploited, UAA and resources it controls could be taken over. The affected product is Cloud Foundry UAA Release OSS before 74.1.0.
Executive priority
Treat as high priority for Cloud Foundry environments because UAA is an identity control point. Affected versions can allow privilege escalation to any scope, creating platform-wide business risk even though the cited evidence does not show active exploitation.
Technical view
The issue is scope validation bypass in CF UAA before 74.1.0. A remote malicious user can submit requested scopes as an array and obtain scopes their client should not receive. CVSS 3.0 is 8.7 with network access, low complexity, high privileges required, no user interaction, and changed scope.
Likely exposure
Exposure is limited to organizations running Cloud Foundry UAA Release OSS versions prior to 74.1.0. Risk is highest where UAA protects important platform or application resources and where high-privilege users or clients exist.
Exploitation context
The source bundle does not identify active exploitation, and KEV is false. The CVSS vector indicates exploitation requires high privileges, so this is not described as an unauthenticated takeover. Impact remains serious because successful scope escalation can control UAA and dependent resources.
Researcher notes
The affected version boundary is clear, but the provided sources do not include deeper exploit telemetry. Note that the record lists CWE-77, while the described behavior is scope manipulation and authorization failure. Avoid assuming affected products beyond Cloud Foundry UAA Release OSS.
Mitigation direction
- Upgrade Cloud Foundry UAA Release OSS to 74.1.0 or later.
- Check the Cloud Foundry advisory for deployment-specific guidance.
- Identify and prioritize internet-reachable or central UAA deployments.
- Review privileged UAA clients and users while remediation is pending.
- Investigate suspicious scope grants or privilege changes.
Validation and detection
- Confirm the deployed CF UAA release version is 74.1.0 or later.
- Inventory all UAA instances, including non-production deployments.
- Review OAuth client scope configurations for unexpected broad access.
- Check logs for unusual scope requests or privilege expansion.
- Verify dependent resources trust only remediated UAA instances.

Improper Neutralization of Special Elements used in a Command ('Command Injection')
Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
