Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in the Assessment Management application. The flaw exists in the admin/add-user.php file where the 'level' parameter is not properly sanitized before being stored in the database. The application uses mysqli_real_escape_string() which escapes SQL special characters but fails to prevent HTML/JavaScript injection. A malicious payload like '><sCrIpT>alert(99)</ScRiPt>' can be stored in the users.level column and later executed when the level is displayed in other pages like admin/add-mark.php.

Detection Guidance

Check for stored XSS in the admin/add-user.php file by inspecting the level parameter input. Look for unsanitized user input in the users.level column of the database. Review admin/add-mark.php and similar files for improper HTML encoding when displaying the level parameter.

Impact Analysis

This vulnerability could allow attackers to inject malicious scripts into the application. When other users access the affected pages, the stored payload executes in their browsers, potentially enabling session hijacking, stealing cookies, or performing phishing attacks. Attackers could impersonate users or gain unauthorized access to sensitive data.

Compliance Impact

This vulnerability could lead to data breaches, exposing personal or sensitive information. Under GDPR, this may result in fines for inadequate security measures. For HIPAA, it could violate patient data protection requirements, leading to penalties. Organizations must address this flaw to maintain compliance.

Mitigation Strategies

Apply input validation and output encoding to the level parameter in admin/add-user.php. Use htmlspecialchars() or similar functions to sanitize stored data. Ensure all files displaying the level parameter (admin/add-mark.php, lecturer/add-mark.php, supervisor/add-mark.php) properly encode HTML output.
