Security readout for executives and security teams
Plain-English summary
Cloud Foundry UAA before 74.0.0 could let an unauthenticated attacker send a crafted SCIM filter link that runs JavaScript in some older browsers. The victim must interact with the link. Business risk is limited but real for organizations still running older UAA releases.
Executive priority
Treat as a routine but necessary security update. It is not evidenced as actively exploited, but internet-facing identity services deserve timely remediation because successful XSS can undermine trust in authentication workflows.
Technical view
CVE-2019-11274 is a CWE-79 XSS issue in Cloud Foundry UAA SCIM filter handling before v74.0.0. It is remotely reachable without attacker authentication but requires user interaction. CVSS 3.0 is 4.3, with low integrity impact and no stated confidentiality or availability impact.
Likely exposure
Exposure is likely limited to Cloud Foundry environments using UAA Release OSS versions prior to v74.0.0, especially where UAA is reachable by users with older browsers.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed as KEV. Exploitation requires a crafted URL and user interaction; older browsers are specifically called out as execution risk.
Researcher notes
Focus validation on UAA SCIM filter input handling and browser execution behavior. Avoid assuming modern-browser exploitability beyond the source language. The available evidence identifies affected versions and impact class but provides limited operational detail.
Mitigation direction
- Upgrade Cloud Foundry UAA Release OSS to v74.0.0 or later.
- Review the Cloud Foundry advisory for deployment-specific remediation guidance.
- Prioritize externally reachable or broadly used UAA deployments.
- Advise users not to open unexpected UAA links until remediation is complete.
Validation and detection
- Inventory Cloud Foundry UAA versions across all foundations and environments.
- Confirm no deployed UAA version is older than v74.0.0.
- Review UAA access logs for unusual SCIM filter URL activity.
- Perform safe XSS regression testing against SCIM filter handling after upgrade.
