Security readout for executives and security teams
Plain-English summary
Cloud Foundry UAA login pages could be embedded in another site because some endpoints lacked X-FRAME-OPTIONS. An attacker could trick a user into interacting with the real UAA interface inside a deceptive page, risking exposure of sensitive account or login information.
Executive priority
Treat this as a moderate-priority identity-interface issue. It is not listed as known exploited, but it affects login workflows and has high confidentiality impact if users are successfully deceived.
Technical view
CVE-2019-3794 affects Cloud Foundry UAA versions prior to v73.4.0. Various UAA frontend endpoints did not set X-FRAME-OPTIONS, enabling clickjacking. CVSS 3.0 is 6.5 with network access, low complexity, no privileges, required user interaction, and high confidentiality impact.
Likely exposure
Organizations running Cloud Foundry UAA, especially internet-accessible or user-facing UAA login frontend sites, may be exposed if running a release before v73.4.0.
Exploitation context
The sources describe remote clickjacking requiring user interaction. The provided KEV flag is false, and the bundle provides no evidence of active exploitation in the wild.
Researcher notes
The source bundle identifies missing X-FRAME-OPTIONS on various UAA frontend endpoints and maps the issue to CWE-284. Evidence does not name specific endpoints, attack campaigns, or compensating controls beyond upgrading/checking vendor guidance.
Mitigation direction
- Upgrade Cloud Foundry UAA to v73.4.0 or later where applicable.
- Review the Cloud Foundry advisory for supported upgrade guidance.
- Prioritize externally reachable UAA login frontends.
- Ensure affected UAA endpoints return X-FRAME-OPTIONS after remediation.
Validation and detection
- Inventory Cloud Foundry UAA deployments and record release versions.
- Identify any UAA instance running before v73.4.0.
- Inspect UAA frontend responses for the X-FRAME-OPTIONS header.
- Confirm remediation in staging before production rollout.
- Document exposed login endpoints and ownership.
