CVE-2025-49185
📋 TL;DR
This cross-site scripting (XSS) vulnerability allows attackers who can create dashboard widgets to inject malicious JavaScript into Transform Functions. When the widget receives data from its data source, the injected code executes in users' browsers. This affects web applications using vulnerable dashboard widget systems.
💻 Affected Systems
- SICK web applications with dashboard widget functionality
📦 What is this software?
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, redirect users to malicious sites, perform actions on behalf of authenticated users, or deploy ransomware payloads through the web interface.
Likely Case
Session hijacking, credential theft, or defacement of dashboard interfaces by authenticated malicious users.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires authenticated access with widget creation privileges; injection is straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory SCA-2025-0007 for specific fixed versions
Vendor Advisory: https://www.sick.com/.well-known/csaf/white/2025/sca-2025-0007.json
Restart Required: Yes
Instructions:
1. Review SICK advisory SCA-2025-0007. 2. Identify affected products and versions. 3. Apply vendor-provided patches. 4. Restart affected services. 5. Verify fix implementation.
🔧 Temporary Workarounds
Restrict Widget Creation Permissions
allLimit dashboard widget creation to trusted administrators only
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Content-Security-Policy: script-src 'self'
🧯 If You Can't Patch
- Implement strict input validation and output encoding for all widget transform functions
- Monitor and audit all widget creation and modification activities
🔍 How to Verify
Check if Vulnerable:
Test if JavaScript can be injected into widget transform functions and executes when data is receivedCheck Version:
Check web application version against vendor's patched version listVerify Fix Applied:
Verify patches are applied and test that script injection no longer executes📡 Detection & Monitoring
Log Indicators:
- Unusual widget creation/modification events
- JavaScript payloads in transform function parameters
Network Indicators:
- Unexpected external script loads from dashboard pages
SIEM Query:
