🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown - check vendor advisory

Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/stored-cross-site-scripting-xss-rle-novas-planmanager

Restart Required: No

Instructions:

1. Contact RLE NOVA for patch information 2. Apply vendor-provided security update 3. Verify input validation and output encoding are properly implemented

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side validation to reject or sanitize HTML/JavaScript in comment and brand parameters

Content Security Policy

all

Deploy strict CSP headers to prevent execution of inline scripts

Content-Security-Policy: default-src 'self'; script-src 'self'

🧯 If You Can't Patch

  • Implement WAF rules to block XSS payloads in comment and brand parameters
  • Disable or restrict access to vulnerable functionality until patch can be applied

🔍 How to Verify

Check if Vulnerable:

Test by submitting <script>alert('XSS')</script> to comment/brand parameters and checking if it executes when page reloads

Check Version:

Check application version in admin interface or contact vendor

Verify Fix Applied:

Attempt same XSS payload and verify it's either blocked, sanitized, or doesn't execute

📡 Detection & Monitoring

Log Indicators:

  • Unusually long comment/brand parameter values
  • HTML/JavaScript patterns in user input fields
  • Multiple failed validation attempts

Network Indicators:

  • POST requests to /index.php with script tags in parameters
  • Unexpected JavaScript loading from application pages

SIEM Query:

source="web_server" AND (uri_path="/index.php") AND (param_name="comment" OR param_name="brand") AND (param_value CONTAINS "<script>" OR param_value CONTAINS "javascript:")
