🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Unknown

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version if available or implementing workarounds.

Input Sanitization

all

Add input validation and output encoding to the password parameter in login.php

Edit login.php and add: htmlspecialchars($_POST['password'], ENT_QUOTES, 'UTF-8');

Content Security Policy

all

Implement CSP headers to prevent script execution from untrusted sources

Add to .htaccess: Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
Or add to PHP: header("Content-Security-Policy: default-src 'self'; script-src 'self'");

🧯 If You Can't Patch

  • Implement web application firewall (WAF) with XSS protection rules
  • Disable the login page and use alternative authentication methods if possible

🔍 How to Verify

Check if Vulnerable:

Test by entering <script>alert('XSS')</script> in password field and checking if script executes

Check Version:

Check software version in admin panel or readme files

Verify Fix Applied:

Test with same payload; script should not execute and special characters should be properly encoded
