CVE-2006-3914
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 · uneditedCross-site scripting (XSS) vulnerability in Blackboard Academic Suite 6.2.3.23 allows remote authenticated users to inject arbitrary HTML or web script by bypassing client-side validation through disabling JavaScript when submitting an essay response, which has no server-side validation before being viewed via "View Attempt Details" in the Gradebook.
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 confidenceStored XSS vulnerability in Blackboard Academic Suite 6.2.3.23 where authenticated users bypass client-side JavaScript validation by disabling JavaScript to inject arbitrary HTML/web script into essay responses. The malicious payload executes when instructors view submissions via 'View Attempt Details' in the Gradebook due to missing server-side validation before rendering user content.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Blackboard Academic Suite versionAccess the system administrator panel or check the installation directory for version information. Look for a file named about.html, version.txt, or similar in the Blackboard installation folder. Alternatively, navigate to the admin interface and locate the system version display.Affected if The installed version is exactly 6.2.3.23
-
Confirm Gradebook module is accessibleVerify that the Gradebook functionality is available in the installation. As this is a core Blackboard feature, check if the 'View Attempt Details' option exists by navigating to the Gradebook section as an instructor account.Affected if The Gradebook with 'View Attempt Details' feature is present and accessible to authenticated users
-
Verify essay response submission capability existsCheck if the assignment feature allowing essay-type responses is enabled. Log in as an authenticated user and attempt to access or create an assignment that accepts long-form text responses.Affected if Users can submit essay or long-text responses through the assignment/assessment module
-
Confirm server-side validation is missingThis is a code-level check. Inspect the server-side script that handles rendering of submitted essay content in the Gradebook view. Look for the absence of input validation or output encoding functions before the content is rendered in 'View Attempt Details'.Affected if User-submitted content in essay responses is rendered without server-side validation or sanitization when viewing attempt details
The environment is affected only if the installed Blackboard Academic Suite version is exactly 6.2.3.23 and the Gradebook with essay submission functionality is in use.

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 dataImplement server-side input validation and output encoding/sanitization for all user-submitted content before rendering in the Gradebook, regardless of client-side validation status.
