🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and output encoding in /_parse/_all_edits.php or migrating to a supported alternative.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize fname and lname parameters before processing
Edit /_parse/_all_edits.php to add: $fname = htmlspecialchars($_POST['fname'], ENT_QUOTES, 'UTF-8'); $lname = htmlspecialchars($_POST['lname'], ENT_QUOTES, 'UTF-8');
WAF Rule Implementation
allDeploy web application firewall rules to block XSS payloads in fname/lname parameters
Configure WAF to block patterns like: <script>, javascript:, onload=, etc. in POST parameters
🧯 If You Can't Patch
- Implement Content Security Policy (CSP) headers to restrict script execution
- Disable or restrict access to the vulnerable /_parse/_all_edits.php endpoint
🔍 How to Verify
Check if Vulnerable:
Test by submitting payload: <script>alert('XSS')</script> in fname or lname parameters to /_parse/_all_edits.phpCheck Version:
Check application files for version information or review installation documentationVerify Fix Applied:
After implementing fixes, test with same XSS payloads and verify they are properly sanitized or blocked📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /_parse/_all_edits.php with script tags or JavaScript in parameters
