📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover, sensitive data theft, or unauthorized system control through tricked user interactions
Likely Case
Unauthorized actions performed in user context, such as changing settings or initiating transactions
If Mitigated
Limited impact with proper frame-busting headers and user awareness training
🎯 Exploit Status
Clickjacking attacks are well-documented and easy to implement with basic HTML skills
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://sick.com/psirt
Restart Required: No
Instructions:
1. Consult SICK PSIRT for specific patch information
2. Apply security headers to web application
3. Test implementation thoroughly
🔧 Temporary Workarounds
Implement X-Frame-Options Header
allPrevents page from being embedded in frames
Add to web server config: X-Frame-Options: DENY
Or: X-Frame-Options: SAMEORIGIN
Implement Content-Security-Policy
allModern alternative with frame-ancestors directive
Add to web server config: Content-Security-Policy: frame-ancestors 'none'
Or: Content-Security-Policy: frame-ancestors 'self'
🧯 If You Can't Patch
- Implement web application firewall rules to add security headers
- Use frame-busting JavaScript (less reliable than headers)
🔍 How to Verify
Check if Vulnerable:
Use browser developer tools to check HTTP response headers for X-Frame-Options or Content-Security-Policy with frame-ancestorsCheck Version:
Check web application version through admin interface or vendor documentationVerify Fix Applied:
Test with clickjacking test tools like OWASP's Clickjacking Tester or manually create test pages📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from same IP
- Unexpected user actions in logs
Network Indicators:
- Requests from unexpected referrers
- Suspicious iframe usage patterns
SIEM Query:
