CVE-2025-0593
📋 TL;DR
This vulnerability allows remote attackers with low privileges to execute arbitrary shell commands on affected SICK devices by exploiting improper neutralization of special elements used in a command. Organizations using vulnerable SICK industrial devices are affected.
💻 Affected Systems
- SICK industrial devices (specific models detailed in vendor advisory)
⚠️ 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 system compromise allowing attackers to execute arbitrary commands, potentially leading to device takeover, data exfiltration, or disruption of industrial operations.
Likely Case
Attackers gain shell access to execute limited commands, potentially enabling lateral movement, data theft, or service disruption.
If Mitigated
With proper network segmentation and access controls, impact is limited to isolated systems with minimal business disruption.
🎯 Exploit Status
Requires low-privileged access to exploit. No public exploit code available at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to SICK advisory SCA-2025-0002 for specific patched versions
Vendor Advisory: https://www.sick.com/.well-known/csaf/white/2025/sca-2025-0002.json
Restart Required: No
Instructions:
1. Review SICK advisory SCA-2025-0002. 2. Identify affected devices. 3. Apply firmware updates provided by SICK. 4. Verify update completion.
🔧 Temporary Workarounds
Network Segmentation
allIsolate affected devices from untrusted networks and implement strict firewall rules
Access Control Restrictions
allLimit user privileges and implement principle of least privilege for device access
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable devices
- Deploy intrusion detection systems to monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vulnerable versions listed in SICK advisory SCA-2025-0002Check Version:
Device-specific command (consult SICK documentation for exact command)Verify Fix Applied:
Verify firmware version matches patched versions in vendor advisory and test functionality📡 Detection & Monitoring
Log Indicators:
- Unusual shell command execution
- Unauthorized access attempts
- Abnormal process creation
Network Indicators:
- Suspicious network traffic to device management interfaces
- Unexpected outbound connections
