CVE-2025-49192
📋 TL;DR
This clickjacking vulnerability allows attackers to embed the vulnerable web application in an invisible frame and trick users into clicking malicious elements. All users of affected SICK industrial control systems are potentially at risk when accessing the web interface.
💻 Affected Systems
- SICK industrial control systems with web interfaces
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could trick users into performing privileged actions, modifying system configurations, or disclosing sensitive industrial control system data.
Likely Case
Attackers create phishing pages that trick users into clicking malicious buttons that appear legitimate, potentially leading to unauthorized actions.
If Mitigated
With proper frame-busting headers, the risk is minimal as browsers will prevent the site from being embedded in frames.
🎯 Exploit Status
Clickjacking attacks are well-understood and easy to implement; no authentication required as it targets the user's browser session
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SICK advisory SCA-2025-0007 for specific patched versions
Vendor Advisory: https://www.sick.com/.well-known/csaf/white/2025/sca-2025-0007.json
Restart Required: Yes
Instructions:
1. Check SICK advisory SCA-2025-0007 for affected products. 2. Apply vendor-provided firmware updates. 3. Restart affected devices. 4. Verify X-Frame-Options headers are properly set.
🔧 Temporary Workarounds
Configure X-Frame-Options Header
allPrevent the web application from being embedded in frames
Add 'X-Frame-Options: DENY' or 'X-Frame-Options: SAMEORIGIN' to HTTP responses
Implement Content Security Policy
allUse CSP frame-ancestors directive to control framing
Add 'Content-Security-Policy: frame-ancestors 'none'' to HTTP responses
🧯 If You Can't Patch
- Implement web application firewall rules to add X-Frame-Options headers
- Use browser extensions that prevent clickjacking for critical users
🔍 How to Verify
Check if Vulnerable:
Test if the web application can be embedded in an iframe by creating a simple HTML page with the target URL in an iframeCheck Version:
Check device firmware version through web interface or consult SICK documentationVerify Fix Applied:
Check HTTP response headers for X-Frame-Options: DENY/SAMEORIGIN or Content-Security-Policy with frame-ancestors directive📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from unexpected iframe referrers
- Unusual configuration changes from user sessions
Network Indicators:
- Web traffic showing site loaded within frames from external domains
SIEM Query:
http.response.headers X-Frame-Options NOT EXISTS OR http.response.headers X-Frame-Options != DENY AND http.response.headers X-Frame-Options != SAMEORIGIN🔗 References
