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.
-
Confirm Code Projects Exam Form Submission is installedLocate the application on the web server. Check for directories containing 'exam' or 'form' in the path, or look for files named 'index.php' with exam/form related content.Affected if The Code Projects Exam Form Submission application version 1.0 is found on the server.
-
Verify the installed version is 1.0Check application files (such as README, version.php, or about page) for version information, or review any version metadata in the source code.Affected if The application version is exactly 1.0.
-
Identify access to the Manage Fastrack Subjects featureNavigate to the application admin panel or subject management section. Look for a feature labeled 'Manage Fastrack Subjects' or similar subject management functionality.Affected if The Manage Fastrack Subjects feature exists and is accessible in the application.
-
Inspect stored subject entries for unsanitized contentAccess the Manage Fastrack Subjects feature and view existing subject entries. Examine the Subject Name and Subject Code fields for any HTML, script tags, or JavaScript-like patterns (such as <script>, javascript:, onerror=, onload=).Affected if Subject entries contain raw HTML, script tags, or JavaScript event handlers in the Subject Name or Subject Code fields without encoding.
-
Verify subject data is displayed to usersLog in as a different user (non-admin) and navigate to any page where subject entries are listed or displayed. Check if the Subject Name and Subject Code values are rendered in the browser.Affected if Subject entries are rendered in user-viewable pages without output encoding.
A user is affected if Code Projects Exam Form Submission version 1.0 is running, the Manage Fastrack Subjects feature is accessible, and subject entries with unsanitized script content exist in the database and are displayed to users.

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 context-aware output encoding for all subject data displayed in the application and add server-side input validation to reject or sanitize HTML/script tags. Consider implementing a Content Security Policy (CSP) as a defense-in-depth measure.
