Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The UAA OAuth approval pages in Cloud Foundry v208 to v231, Login-server v1.6 to v1.14, UAA v2.0.0 to v2.7.4.1, UAA v3.0.0 to v3.2.0, UAA-Release v2 to v7 and Pivotal Elastic Runtime 1.6.x versions prior to 1.6.20 are vulnerable to an XSS attack by specifying malicious java script content in either the OAuth scopes (SCIM groups) or SCIM group descriptions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Cross-site scripting (XSS) vulnerability in Cloud Foundry UAA OAuth approval pages allows attackers to inject malicious JavaScript via OAuth scopes (SCIM groups) or SCIM group descriptions. When users view the OAuth approval page, the unsanitized scope/description content is rendered in the browser, enabling session hijacking or credential theft.

MitigationUpgrade UAA, Login-server, and Cloud Foundry to versions beyond the vulnerable ranges (e.g., Pivotal Elastic Runtime 1.6.20+, UAA v3.2.1+). Alternatively, sanitize OAuth scope and SCIM group description inputs to strip executable script content before display.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check UAA version
    Query the UAA API endpoint /uaa/info or check the deployed UAA version in BOSH manifest. For example: curl -k https://uaa.<your-domain>/uaa/info
    Affected if The UAA version is 2.x <= 2.7.4.1, 3.0.0, 3.0.1, 3.1.0, or 3.2.0
  2. Check Login Server version
    Check the deployed Login Server version in BOSH manifest or configuration files under /var/vcap/jobs/login-server/config/
    Affected if Any version of Login Server is deployed (all versions are affected)
  3. Check Cloud Foundry Elastic Runtime version
    Query cf curl /v2/info or check the cf deployment manifest. Run: cf curl /v2/info
    Affected if Elastic Runtime version is 1.6.0 through 1.6.11, or Cloud Foundry is versions 208-219
  4. Verify OAuth approval page rendering
    Create a test OAuth client with a scope containing a script tag like <script>alert(1)</script>, then authorize and inspect the OAuth approval page HTML source to see if the scope is rendered unsanitized
    Affected if The OAuth approval page displays scope values or SCIM group descriptions as raw HTML without encoding or sanitization

You are affected if your environment runs any combination of UAA <= 2.7.4.1, UAA 3.x <= 3.2.0, Login Server, Cloud Foundry 208-219, or Elastic Runtime 1.6.0-1.6.11, AND your OAuth approval page renders SCIM group names or descriptions without HTML encoding.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 2.7.4.1
Interim mitigation

Upgrade UAA, Login-server, and Cloud Foundry to versions beyond the vulnerable ranges (e.g., Pivotal Elastic Runtime 1.6.20+, UAA v3.2.1+). Alternatively, sanitize OAuth scope and SCIM group description inputs to strip executable script content before display.
