CVE-2019-11278: Privilege Escalation via Blind SCIM Injection in UAA

CF UAA versions prior to 74.1.0, allow external input to be directly queried against. A remote malicious user with 'client.write' and 'groups.update' can craft a SCIM query, which leaks information that allows an escalation of privileges, ultimately allowing the malicious user to gain control of UAA scopes they should not have.

Security readout for executives and security teams

Plain-English summary

CVE-2019-11278 is a high-severity Cloud Foundry UAA flaw. An already-privileged remote user could abuse SCIM query handling to learn sensitive information and escalate control over UAA scopes. This is not a drive-by issue, but it can undermine identity and authorization boundaries.

Executive priority

Treat as priority remediation for Cloud Foundry environments using UAA before 74.1.0. The prerequisite privileges reduce broad internet risk, but identity-scope compromise can create serious business impact if an insider, compromised client, or overprivileged automation account abuses it.

Technical view

CF UAA releases before 74.1.0 allowed external input to be queried directly in SCIM handling. A remote actor with both client.write and groups.update could use blind SCIM injection to disclose information and gain UAA scopes they should not control. CVSS is 8.7 with high confidentiality and integrity impact.

Likely exposure

Exposure is limited to Cloud Foundry UAA Release OSS deployments before 74.1.0. Risk is highest where clients or users hold both client.write and groups.update. Systems not running UAA, upgraded UAA versions, or environments without those grants are less likely exposed.

Exploitation context

The provided sources do not cite active exploitation, and the CVE is not listed as KEV in the bundle. Exploitation requires network access and high existing privileges, but successful abuse can cross authorization boundaries and affect sensitive identity-management scopes.

Researcher notes

Evidence supports a blind SCIM injection leading to information leakage and privilege escalation in CF UAA before 74.1.0. The bundle does not include proof of exploitation in the wild, detailed patch notes, or affected downstream distributions. Avoid assuming impact beyond the named OSS UAA release.

Mitigation direction

  • Upgrade CF UAA Release OSS to 74.1.0 or later.
  • Review vendor advisory for deployment-specific guidance.
  • Restrict client.write and groups.update to tightly controlled principals.
  • Audit recent UAA scope and group changes for unexpected activity.
  • Review privileged clients for unnecessary authorization-management access.

Validation and detection

  • Inventory deployed UAA versions and identify releases before 74.1.0.
  • List principals holding both client.write and groups.update.
  • Check UAA audit logs for unusual scope or group modifications.
  • Confirm upgraded environments report UAA 74.1.0 or later.
  • Verify privileged grants are justified and documented.
