Patch Version: Unknown
Vendor Advisory: http://studentmanage.com
Restart Required: No

🔧 Temporary Workarounds
Implement Input Validation
allAdd server-side validation to sanitize user input in the 'Add A New Course' module.
// Example PHP validation: $course_name = htmlspecialchars($_POST['course_name'], ENT_QUOTES, 'UTF-8');
Enable Content Security Policy (CSP)
allImplement CSP headers to restrict script execution sources.
// Add to web server config: Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Restrict access to the StudentManage application to trusted users only using network segmentation or firewall rules.
- Implement a Web Application Firewall (WAF) with XSS protection rules to block malicious payloads.
🔍 How to Verify
Check if Vulnerable:
Attempt to inject a basic XSS payload like <script>alert('XSS')</script> into the 'Add A New Course' module and check if it executes when viewing the course.Check Version:
Check the application's admin panel or configuration files for version information. Typically found in README files or about pages.Verify Fix Applied:
After applying fixes, test with the same XSS payloads to ensure they are properly sanitized and do not execute.📡 Detection & Monitoring
