CVE-2025-49183
📋 TL;DR
This vulnerability exposes REST API communications to interception by using unencrypted HTTP instead of HTTPS. Attackers can eavesdrop on traffic between users and the web server, potentially capturing sensitive data and media files. Organizations using affected SICK products with REST API enabled are impacted.
💻 Affected Systems
- SICK industrial devices with REST API 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
Complete compromise of all API communications including credentials, configuration data, and sensitive media files, leading to data theft, system manipulation, or lateral movement within the network.
Likely Case
Interception of unencrypted API traffic revealing operational data, configuration details, and potentially authentication credentials for adjacent systems.
If Mitigated
Limited exposure with only non-sensitive data accessible if proper network segmentation and monitoring are implemented.
🎯 Exploit Status
Exploitation requires network access to intercept traffic; no authentication needed as it's a protocol-level vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Consult 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. Review SICK advisory SCA-2025-0007. 2. Identify affected devices. 3. Apply vendor-provided firmware updates. 4. Restart devices. 5. Verify HTTPS is enforced.
🔧 Temporary Workarounds
Enable HTTPS Enforcement
allConfigure web server to redirect all HTTP traffic to HTTPS and disable HTTP entirely
Device-specific configuration required; consult SICK documentation
Network Segmentation
linuxIsolate affected devices in separate VLANs with strict access controls
# Example firewall rule to restrict access
# iptables -A INPUT -p tcp --dport 80 -j DROP
🧯 If You Can't Patch
- Implement network-level TLS termination using reverse proxy or load balancer
- Deploy network monitoring and IDS/IPS to detect interception attempts
🔍 How to Verify
Check if Vulnerable:
Use curl or browser to access REST API endpoints via HTTP; if accessible without HTTPS redirect, vulnerableCheck Version:
Device-specific; typically via web interface or SNMP query to device firmware versionVerify Fix Applied:
Test API endpoints - HTTP requests should redirect to HTTPS or be blocked; verify TLS certificates are valid📡 Detection & Monitoring
Log Indicators:
- HTTP traffic to REST API endpoints
- Failed HTTPS connection attempts
- Unusual outbound data transfers
Network Indicators:
- Cleartext HTTP traffic on port 80 to device IPs
- ARP spoofing or MITM attack patterns
SIEM Query:
source_port:80 AND dest_ip:[device_ips] AND protocol:HTTP AND NOT user_agent:"health_check"🔗 References
