CVE-2025-64302
📋 TL;DR
This CVE describes a cross-site scripting (XSS) vulnerability in dashboard components where insufficient input sanitization allows attackers to inject malicious scripts. Attackers can trigger device errors leading to information disclosure or data manipulation. Organizations using affected Advantech industrial control systems are at risk.
💻 Affected Systems
- Advantech industrial control systems with dashboard functionality

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of dashboard functionality leading to data theft, unauthorized data manipulation, and potential lateral movement within industrial control networks.
Likely Case
Information disclosure through error messages revealing system details, session hijacking via stolen cookies, or limited data manipulation within dashboard interfaces.
If Mitigated
Minimal impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity but may require some user interaction or authentication depending on implementation
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Advantech advisory for specific patched versions
Vendor Advisory: https://www.advantech.com/emt/contact
Restart Required: Yes
Instructions:
1. Contact Advantech support for patch availability 2. Apply vendor-provided patches 3. Restart affected systems 4. Verify fix implementation
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy' header with appropriate directives to web server configuration
Input Validation Filter
allImplement server-side input validation for dashboard parameters
Implement input sanitization functions for all user-controlled dashboard fields
🧯 If You Can't Patch
- Network segmentation: Isolate affected systems from untrusted networks
- Web Application Firewall: Deploy WAF with XSS protection rules
🔍 How to Verify
Check if Vulnerable:
Test dashboard inputs with XSS payloads like <script>alert('test')</script> and observe if scripts executeCheck Version:
Check system version through dashboard interface or vendor-specific CLI commandsVerify Fix Applied:
Retest with XSS payloads after patching; scripts should not execute and inputs should be properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual error messages containing script tags
- Multiple failed dashboard access attempts with special characters
Network Indicators:
- HTTP requests containing script tags in URL parameters or POST data
- Unusual traffic patterns to dashboard endpoints
SIEM Query:
source="web_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=") AND uri="*/dashboard*"
