Edit cliAction.php to add: $m = htmlspecialchars($m, ENT_QUOTES, 'UTF-8'); before processing.
Web Application Firewall (WAF) Rule
allBlock requests containing suspicious patterns in the 'm' parameter.
Add WAF rule to filter: m parameter containing <script>, javascript:, or other XSS indicators.
🧯 If You Can't Patch
- Implement Content Security Policy (CSP) headers to restrict script execution.
- Disable or restrict access to the task.php endpoint if not required.
🔍 How to Verify
Check if Vulnerable:
Test by accessing task.php?m=<script>alert('XSS')</script> and check if script executes in browser.Check Version:
Check RockOA version in admin panel or configuration files; look for '2.7.0'.Verify Fix Applied:
After applying fixes, test the same payload; script should not execute and input should be sanitized.📡 Detection & Monitoring
