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
Ellucian Banner Self-Service before the April T2 release (2025-04-23) contains a stored cross-site scripting vulnerability in the course search functionality that allows authenticated Banner ERP users to inject malicious payloads into faculty and course fields by exploiting missing HTML encoding during DOM insertion. An attacker with Banner ERP write access can store malicious JavaScript in fields such as faculty displayName, emailAddress, subjectDescription, or courseTitle; these values are subsequently served unsanitized by the unauthenticated getFacultyMeetingTimes API endpoint, causing arbitrary script execution in the browser of any user who views the affected course's meeting times.

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

Stored cross-site scripting vulnerability in Ellucian Banner Self-Service where authenticated users with Banner ERP write access can inject malicious JavaScript into faculty fields (displayName, emailAddress) or course fields (subjectDescription, courseTitle). These values are served unsanitized by the unauthenticated getFacultyMeetingTimes API endpoint, causing arbitrary script execution in browsers of users viewing affected course meeting times.

MitigationApply the vendor April T2 release (2025-04-23) patch. Until patch is available, implement output encoding on the getFacultyMeetingTimes API endpoint and add input validation on all faculty/course field creation interfaces.

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 the installed Ellucian Banner Self-Service version
    Locate the version number in the application admin panel, system information page, or installation documentation. Compare it against the April T2 2025 release.
    Affected if The installed version is before the April T2 2025 release and the getFacultyMeetingTimes endpoint is accessible.
  2. Verify getFacultyMeetingTimes API endpoint accessibility
    Attempt to access the getFacultyMeetingTimes API endpoint without authentication using a web browser or HTTP client. Check if the endpoint returns data without requiring login credentials.
    Affected if The endpoint is accessible without authentication and returns faculty/course data.
  3. Inspect API response for unsanitized output
    Call the getFacultyMeetingTimes endpoint and examine the JSON or HTML response for fields displayName, emailAddress, subjectDescription, and courseTitle. Look for any raw user-supplied content that may contain script tags or HTML elements.
    Affected if The response contains unescaped HTML or JavaScript in any of the affected fields.
  4. Confirm write access to affected fields exists
    Log in as an authenticated user with write access to faculty or course management. Attempt to create or modify records containing displayName, emailAddress, subjectDescription, or courseTitle with test script payloads (e.g., <script>alert(1)</script>).
    Affected if The system accepts and stores the payload without sanitization.

You are affected if your Banner Self-Service version predates the April T2 2025 release AND the getFacultyMeetingTimes endpoint is exposed and returns unsanitized user-controlled content in displayName, emailAddress, subjectDescription, or courseTitle fields.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor April T2 release (2025-04-23) patch. Until patch is available, implement output encoding on the getFacultyMeetingTimes API endpoint and add input validation on all faculty/course field creation interfaces.

Recommended fix Moderate confidence

Ellucian Banner Self-Service April T2 release (2025-04-23) or later

  1. Identify current Ellucian Banner Self-Service version by checking the system administration console or Banner ERP version information
  2. Schedule a maintenance window for the upgrade process
  3. Verify backup of current Banner Self-Service database and configuration files
  4. Upgrade Ellucian Banner Self-Service to the April T2 release (2025-04-23) or later using Ellucian's official upgrade procedures
  5. After upgrade, verify the getFacultyMeetingTimes API endpoint now properly sanitizes HTML entities in faculty displayName, emailAddress, subjectDescription, and courseTitle fields
  6. Confirm that course search functionality properly encodes output before DOM insertion
  7. Review Banner ERP user access controls to ensure only authorized personnel have write access to faculty and course fields
